its obviously not child labor or economy based because those have nothing to do with the environment so its the other three.
Answer:
-degrades vegetation
-increases soil erosion
-creates competition for water
Explanation:
There are many environmental impacts caused by mining, economic and industrial activity that consists in the research, exploration, extraction and processing of ores present in underground deposits. The same is true of mining for materials used in smart devices. This human activity destroys nature and creates very damaging ecological imbalances that diminishes the quality of life not only for humans but for all living beings.
Mining causes pollution of water resources by decreasing the amount of drinking water and increasing competition for water in some places. In addition, it causes soil degradation through erosion and causes loss of diversity by degrading vegetation and animal life.

Chloroplasts are specialized units in plant and algal cells responsible for photosynthesis, containing chlorophyll a for light capture.
Chloroplasts are organelles found in plant and algal cells with the distinctive role of conducting photosynthesis. They contain the green pigment chlorophyll a, which is essential for capturing light energy. The structure of chloroplasts, including their membranes and thylakoids, enhances the efficiency of photosynthesis. Thylakoids are stacked in grana to increase the surface area for light absorption. Membranes house components necessary for the electron transport chain and provide a compartmentalized environment for the chemical reactions of photosynthesis. During photosynthesis, chlorophyll a absorbs light energy and emits an electron, starting the process of an electron transport chain. Electron carriers, such as the molecules NADP+ and ATP, are then used to transport energy around the cell, particularly in the synthesis of organic molecules in the Calvin cycle. The electron transport chain is essential for converting light energy into chemical energy, stored in ATP and NADPH, used to produce sugars from carbon dioxide.

Jen makes a Venn diagram to compare active transport and passive transport
Answer:
Explanation: Active transport uses energy (ATP) for the moving the molecules in and out of the cellular membranes and therefore remain active, while in passive transport the molecules do not use energy for their movements and so the name is given as passive.
Active transport requires the expenditure of energy in the form of ATP to move substances against a concentration gradient, while passive transport does not require any energy and permits substances to move naturally from an area of higher concentration to one of lower concentration.
Explanation:The fundamental difference between active transport and passive transport involves the need for energy. Active transport requires energy in the form of ATP to move molecules against a concentration gradient - often through a membrane protein structure that functions as a pump. A known example is the sodium-potassium pump that uses energy to transport sodium out of and potassium into cells, both against their concentration gradient.
On the other hand, passive transport, does not require energy. Substances move from an area of higher concentration to lower concentration without the use of ATP or any form of energy. Passive diffusion and facilitated diffusion are two examples of passive transport.
In active transport, substances usually move from an area of low concentration to an area of high concentration, which is often termed as moving 'uphill'. The cell needs to expend energy in the form of ATP for this process. Passive transport happens naturally and does not require energy, as substances move from an area of high concentration to an area of lower concentration, going 'downhill'.

True Or False: All of an organism's cells has the exact same DNA Explain how you know this is true:
Answer: True.
Explanation:
All the organism cells read the same genetic blueprint. So they all have the exact same DNA.
True. All of an organism's cells have the exact same DNA.
What is DNA?The DNA in an organism is present within the nucleus of every cell and contains the genetic information necessary for the development, functioning, and reproduction of that organism. During the process of cell division, the DNA is replicated, and each daughter cell receives an identical copy of the parent cell's DNA.
This means that all cells in an organism, whether they are skin cells, muscle cells, or nerve cells, contain the same genetic information encoded in the DNA. However, not all genes in the DNA are actively expressed in every cell. Different cells express specific sets of genes that are relevant to their particular functions and characteristics. This process of gene regulation allows cells to differentiate and specialize into various cell types while still sharing the same DNA.
Exceptions to this general rule occur in certain cases such as somatic mutations, which can introduce changes in specific cells' DNA during an organism's lifetime. Additionally, some organisms, such as certain types of plants, may exhibit genomic mosaicism, where different cells contain distinct variations of the DNA due to somatic mutations or epigenetic modifications. However, on a fundamental level, the DNA sequence within an organism's cells is the same.

What are the three groups of animals in
Aristotle's classification system?
Land, Water and Air are the three sub-groups of animals in Aristotle's classification system. He also classified on basis of red blood cells and without red blood cells.
Explanation:Aristotle is very popular in ancient Greece and he is very popular in the field of biology and mathematics. He divided the living organisms into two classes called the Plants and the Animals. He divided the animals into two classes – one which contains red blood cells and the other which didn’t contain any red blood cells.
He also noticed that most of the organisms which contained red blood cells are vertebrates i.e they contained a body vertebral column in their back. So they were called as vertebrates and the others were called as invertebrates.
A woman at 36 weeks’ gestation is admitted to the hospital to receive a tocolytic medication in an attempt to stop labor. In addition, betamethasone (Celestone) is prescribed to enhance fetal lung maturity. The prescription reads: administer betamethasone 12 my IM daily for 3 days. The betamethasone comes in a vial labeled 6mg/mL. How many millimeters should the nurse administer each day?
Answer:
The answer is 2 milliliters or 2 mL.
Explanation:
Betamethasone is considered a steroid medication. It is used to treat varieties of condition such as skin rashes, arthritis and in the case above, fetal lung maturity. When it comes to fetal lung maturity, Betamethasone is usually administered to women who are in the gestation period of 34 weeks to 36 weeks, depending on the condition. It is administered through the muscles also known as "IM" or "intramuscular" and the usual dosage is 12 mg. In the case above, it is asking for the mililiters of administration considering that the order was 12 mg IM daily for three days. Since the Betamethasone comes in a 6mg/mL vial, you have to compute how much Betamethasone is to be given.
If there's 6 mg of Betamethasone per 1 mL, then this means that there's 12 mg of the medication in 2 mL.
So, the answer is 2 mL.

what are the two modes through which the hypothalamus causes the release of hormones by pituitary gland?
Answer:
Explanation:
There are two sets of nerve cells in the hypothalamus that produce hormones. One set sends the hormones they produce down through the pituitary stalk to the posterior lobe of the pituitary gland where these hormones are released directly into the bloodstream. These hormones are anti-diuretic hormone and oxytocin.
The hypothalamus influences the pituitary gland's hormone release through hormonal and neural stimuli, involving releasing/inhibiting hormones for the anterior pituitary and direct secretion of hormones like oxytocin and vasopressin for the posterior pituitary.
The two modes through which the hypothalamus causes the release of hormones by the pituitary gland are hormonal stimuli and neural stimuli. The hormonal stimuli involve the hypothalamus producing hormones that stimulate the anterior portion of the pituitary gland to release other hormones regulating different endocrine glands. On the other hand, the neural stimuli method involves the neurons of the hypothalamus synthesizing hormones like oxytocin and vasopressin (or Anti-diuretic Hormone (ADH)), which are sent directly to the posterior portion of the pituitary gland and secreted into the bloodstream.
In the first mode, the hypothalamus secretes releasing hormones and inhibiting hormones that travel through capillaries to the anterior lobe of the pituitary gland, stimulating it to either release or stop releasing various pituitary hormones. For example, thyroid-stimulating hormone, released by the anterior pituitary, then stimulates the thyroid gland to produce hormones T3 and T4. The second mode is characterized by direct hormonal influence, where hormones like oxytocin and vasopressin produced by hypothalamic neurons travel via the infundibulum directly to the posterior part of the pituitary gland.

what does selectively permeable mean?
Answer:
Selectively permeable means a membrane allows the passage of some molecules or ions and inhibits the passage of others.
Explanation:
Hope that helps :)
Answer:
Selective permeable means- to allow some molecules to pass and inhibit other molecules.
Explanation: The capacity to filter molecules to transport in or out of the cell is selective permeability.
Selective permeable membrane facilitates passage of specific molecules on the basis of some specific criteria. This kind of transport is ACTIVE TRANSPORT and requires energy.
Example is lipid bilayer of the cell membrane. It has both semipermeable abd selective permeable quality. The semipermeable layer allows passage of uncharged solutes. Lipid soluble molecules as fat soluble vitamins and some hormones can pass through the hydrophilic layer. Water can pass through the semipermeable membrane by osmosis and carbon dioxide and oxygen can pass through diffusion from this semipermeable membrane.
But for polar molecule, small ions, it is not easy to pass through this lipid bilayer. They passed through the transmembrane channels. Other large molecules pass through active transport. In active transport energy is required in the form of ATP.
A human adult has approximately 37 trillion (3.7 x 1013) cells in their body. Each cell has roughly 6.5 picograms (6.5 x 10-12 grams) of DNA.
How much DNA (in grams) is in an adult human’s body? (Show your work)
240.5 gram DNA is in an adult human’s body.
Explanation:
DNA is the genetic material in human body. It is given that each human cell has approximately 6.5 picograms of DNA. It is also given that there are 37 trillion cells in the body.
We have to calculate the amount of DNA in human body.
Number of cells=37 trillion = [tex]3.7 \times 10^1^3[/tex]
Amount of DNA per cell= 6.5 picogram = [tex]6.5 \times 10^-^1^2g[/tex]
Total amount of DNA in body= [tex]3.7 \times 10^1^3 \times 6.5 \times 10^-^1^2[/tex]
=240.5 g
Final answer:
To find the total amount of DNA in an adult human body, multiply 37 trillion cells by 6.5 picograms per cell and convert to grams. The result is approximately 240.5 grams of DNA.
Explanation:
To calculate the total amount of DNA in an adult human body, we will multiply the number of cells by the amount of DNA per cell. According to the question, an adult has approximately 37 trillion cells, and each cell has roughly 6.5 picograms of DNA. To find the total DNA in grams, we proceed as follows:
Total DNA (in grams) = number of cells ×amount of DNA per cell
Total DNA (in grams) = 37 trillion cells × 6.5 picograms/cell
We then convert the number of cells to a numerical value and picograms to grams:
Total DNA (in grams) = (3.7 × 10¹³ cells) × (6.5 ×10⁻¹² grams/cell)
Now, we multiply these two values:
Total DNA (in grams) = 3.7× 6.5 ×10¹³ × 10⁻¹²
Total DNA (in grams) = 24.05 10¹
Total DNA (in grams) = 240.5 grams
Therefore, the correct answer is that an adult human body contains approximately 240.5 grams of DNA.
Name 2 limiting factors as depth increases in the benthic zone
Answer:
As depth increases in the benthic zone, there is a high pressure and limited light.
Explanation:
Benthic zone begins at the shoreline and extends downwards with the continental shelf. The benthic zone covers 70% of all earth. It can host ecosystems such as a coral reef and kelp forest. In some parts of the benthic zone, at a deeper water zone, there is high pressure, low temperature and low sunlight.
Pressure: As depth increases in the benthic zone, pressure also increases. High pressure in the zone makes a homogeneous environment and lack of oxygen develop anaerobic zone formation.
Light: In deep waters (between 200 and 1000 m), light is unable to penetrate to the lower level. Insufficient light leads toward a low photosynthesis rate which is the reason that food source comes from dead and decaying organisms drifting down from upper layers. This condition also leads to the formation of anaerobic conditions.
Two factors that limit life in the benthic zone as depth increases are the availability of light for photosynthesis and the increase in pressure.
Explanation:Two limiting factors associated with increased depth in the benthic zone include light availability and pressure. First, light availability decreases as depth increases, affecting the ability of organisms to carry out photosynthesis. This results in fewer plant species and a distinct shift in the types of organisms found in these deeper areas.
Secondly, the pressure increases significantly in the benthic zone as depth increases, which can affect the physiology of many organisms. It makes the survival hard for them.

lifecycle of plasmodium in human host
Life cycle of plasmodium in human host consists of 7-10 days survival, causing infection and eradication after getting treatment.
Explanation:Plasmodium is the malaria parasite that causes malaria in humans. The parasite requires two hosts so the life cycle of the parasite includes vertebrates and insect hosts. The life cycle begins from a blood-feeding insect and then into a human host.
When a blood-feeding insect, say a female Anopheles mosquito, makes contact with a human body, it injects parasites in the form of 'sporozoites' into the body. This makes human the second host. The sporozoites then travel through the blood stream and enter lever where they first begin to multiply asexually. This continues for 7 to 10 days without any evidence of symptoms. Then they begin to multiply in red blood cells and continue until the cell bursts. 'Merozoites' are released after each cell break that continue the cycle of multiplication and infect the other red blood cells. Humans spike fever when parasites break free and enter bloodstream, showing the symptoms of Malaria.

the Plasma membrane forms a what between the inside and outside of the cell?
Plasma membrane forms a stable barrier.
Explanation:Cell membrane is a thin flexible membrane, it is present in every living cell.It is also known as plasma membrane or cytoplasmic membrane. This membrane is selectively permeable to organic molecules and ions. It is made up of proteins and lipidsThis membrane forms a stable barrier between two aqueous compartments i.e. to separate the inside of cells from the outside. Cell membrane separates the cytoplasm of the cell from the surroundings.Result: Plasma membrane act as a barrier to protect the cell content from the surroundings.
Final answer:
The plasma membrane acts as a selective barrier between a cell's cytoplasm and the external environment, strictly controlling what substances can enter or leave the cell, thereby maintaining homeostasis.
Explanation:
The plasma membrane, often referred to as the cell membrane, plays a critical role in cellular function. It forms a selective barrier between the internal cytoplasm and the external environment of the cell. As such, the plasma membrane enables the cell to maintain a stable internal environment, also known as homeostasis, by controlling what enters and exits the cell. This selective barrier features selective permeability, meaning it only allows certain substances to pass through while blocking others, maintaining the delicate balance necessary for the cell's survival.
Composed mainly of a bilayer of phospholipids along with proteins, cholesterol, and carbohydrates, the plasma membrane's structure is essential for its function. The hydrophilic (water-attracting) heads of phospholipids face outward and inward toward the water-rich environments, while the hydrophobic (water-repelling) tails face each other, forming the membrane's interior. This arrangement creates a semi-permeable membrane, with protein channels and transporters that assist in the selective movement of molecules.
if the genetic code used four bases as a code instead of three how many code units could be encoded? and why?
If the genetic code used four bases as a code instead of three then 256 units could be encoded.
Explanation:
There are 4 DNA bases that can make up the hereditary code. On the off chance that the codon for every amino corrosive was comprised of just 2 bases, just 16 unique codons would be conceivable.
Given:
1 Bases = [tex]4[/tex] DNA bases
2 Bases = [tex]4^2 = 16[/tex] DNA bases
3 Bases = [tex]4^3 = 64[/tex] DNA bases
4 Bases = [tex]4^4 = 256[/tex] DNA bases
Unmistakably this isn't sufficient. Be that as it may if every ha a codon made up of 3 bases (similar to the case) there are 64 potential blends which are all that could possibly be needed.
So for 4 bases, just 256 unique codons would be conceivable.

Why is it commonly believed that carbon dioxide is responsible for global warming? Select 2 options. Carbon dioxide levels in the Earth’s atmosphere have been steadily decreasing. Carbon dioxide levels in the Earth’s atmosphere have been steadily increasing. Carbon has a longer average lifetime in the atmosphere. Carbon has a shorter average lifetime in the atmosphere. Other greenhouse gases amplify the effect of carbon dioxide.
Answer:
Option B and D are correct as the Carbon dioxide levels in the Earth’s atmosphere have been steadily increasing and other greenhouse gases amplify the effect of carbon dioxide.
Explanation:
As we all are aware that increasing rate of carbon dioxide is responsible for global warming. Scientists note that the average temperature on Earth is increasing over time. They believe that a contributing factor is the greenhouse effect.
This effect is caused by the formation of greenhouse gases, such as methane, water vapor, and carbon dioxide. Increasing the amount of greenhouse gases in the atmosphere is considered to be the cause of global warming and climate change. Water vapor, carbon dioxide, methane, nitrous oxide and ozone are main green house gases.
Carbon dioxide is steadily increasing in the atmosphere over hundreds of years and it has a longer life span than most of the gases.
Option B and C
Explanation:Carbon dioxide is the most prominent greenhouse gas of atmosphere. It is very much responsible for increasing the temperature of Earth's surface by capturing the long wave infrared lights emitted by Earth's surface.
Due to industrial revolution, various natural calamities and huge increase in population over the last few centuries, amount of carbon dioxide is increasing in atmosphere significantly. And the half life of carbon dioxide in atmosphere is around 200 years which is much more than other significant greenhouse gases. This leads to the significant contribution of carbon dioxide to greenhouse effect.

How does static electricity result in cloud-to-ground lightning
Answer:
When the positive and negative charges grow large enough, a giant spark - lightning - occurs between the two charges within the cloud. This is like a static electricity sparks you see, but much bigger. Most lightning happens inside a cloud, but sometimes it happens between the cloud and the ground.
Explanation:
Final answer:
Static electricity results in cloud-to-ground lightning by creating a large electric field between the cloud, acting as one plate of a capacitor, and the ground. The discharge process involves a downward step-leader followed by an upward return stroke which we observe as lightning.
Explanation:
Static electricity leads to cloud-to-ground lightning due to the charge separation within the cloud and between the cloud and the ground. During an electrical storm, the cloud and the ground can be likened to a parallel-plate capacitor. The bottom of the cloud accumulates negative charges through frictional electricity caused by collisions of ice particles in the upper atmosphere. These negative charges repel negative charges on the Earth's surface, inducing a net positive charge below the thunderstorm. When the electric field's magnitude between the cloud and ground exceeds the critical value (Ec), the air gets ionized, and lightning can occur.
The lightning discharge process begins with a stream of electrons, known as a step-leader, descending towards the ground in a branching, ionized channel. When this step-leader nears the ground, a positively charged return stroke moves upwards to meet it. This creates a conducting path that allows for a massive transfer of electrons from cloud to ground and results in the bright flash and thunder that characterizes a lightning strike. The process can repeat numerous times along the same path in a single lightning strike, making lightning appear to flicker.
