The first statement, “We never get to see the far side of the moon” is true among all the statements given.
Explanation:
We only see one side of the moon from Earth, which is commonly referred to as the “near” side of the moon. We are able to see this side through our naked eyes due to the sunlight reflecting of the surface of the moon.
However, this is not to say that the far side of the moon does not receive sunlight at all. It does receive, but it’s just that the far side of the moon never faces the Earth and hence we never see it.
Having said that, the other statements are false. The near side itself goes through weeks of darkness, where it is not lit up by the Sun. The moon has its own axis upon which it rotates. And the moon orbits the Earth and one full rotation takes about 28 days.
Final answer:
The true statement is that we never see the far side of the moon from Earth because the Moon is in synchronous orbit. The near side is always facing Earth due to the Moon's rotational period matching its orbital period. The other statements are false.
Explanation:
Out of the options provided, the true statement is 1. We never get to see the far side of the moon. The Moon is in synchronous orbit around Earth, which means it rotates on its axis in the exact amount of time it takes to orbit Earth. This causes the near side of the Moon to always face the Earth while the far side always faces away. We can see different amounts of the near side illuminated by the sun over the course of a month, which are the phases of the Moon.
The other statements are false:
2. The side of the moon we see is not always illuminated since we observe a range of phases from new moon to full moon.3. The moon does rotate, which keeps the same side facing Earth due to its synchronous rotation.4. The moon indeed orbits the Earth approximately every 28 days.Which is a way that society controls science?

Answer:
The correct option is A) People pass laws to restrict some research.
Explanation:
When it comes to the field of science, the society tends to be more concerned about the ethics which need to be properly followed so that science does not turn out to be a devastating field. For example, the ethics brought about by society has restricted scientists to try human cloning on the whole. Although, cloning or parts such as tissues and organs can be done but cloning of the entire human individual is considered unethical and is restricted. This is because science always remains beneficial and not devastating for humans.
Imagine that you are the advocate for a specific health topic and that you want to create a public service announcement to raise awareness in your community. What health topic would you choose and what medium would you use to convey your message?
Answer:
"The health topic I would chose would probably be tobacco use. I would most likely have one of those pointers and a big poster with everything needed written down on it."
Explanation:
Most of the death occurs due to the smoking rather than alcohol, car crash, AIDS, murder and drugs. Because smoking leads to the heart disease which ultimately causes stroke, chronic lung problems and various other disorders. This may also include the emphysema and bronchitis. The people who use to do smoking cannot taste the food like they previously used to. It also curbs the appetite. Acting as appetite suppressant.

Which of the following would be an adaptation that would help eukaryotic cells increase the surface area to volume ratio and increase the efficiency of the cell?
A) all of these are correct B) long thin cells such as nerve cells.
C) internal compartments that move proteins throughout the cell
D) infoldings of the plasma membrane such as microvilli
All of them are correct.
Option A.
Explanation:The eukaryotic cells in a multicellular organism are specialized to perform certain functions. These cells do adapt to perform their functions easily and efficiently.
In cells like neurons, the plasma membrane are required to transfer the electrical impulse from dendron to axon. But the volume of cell is immaterial for this function. So the cells become long and thin, to perform its soul function.
The villi in small intestine are supplied with cells that has to absorb nutrients from food. This makes the cell have foldings of cell membrane called microvilli to increase the surface area. This is necessary for efficient absorption of nutrients.
All the choices listed, including long thin cells, internal compartments, and specifically infoldings of the plasma membrane like microvilli can help eukaryotic cells increase their surface area to volume ratio, thus increasing cell efficiency.
Explanation:All the choices mentioned can attribute to an increase in the surface area to volume ratio in eukaryotic cells, therefore increasing the efficiency of the cell. However, the main contributor might be D) infoldings of the plasma membrane such as microvilli.
Microvilli are small protrusions on the cell surface that increase the surface area available for absorption, thus increasing the efficiency of the cell. Additionally, having long thin cells like nerve cells or having internal compartments also can increase surface area to allow more interactions to take place within the cell.
Therefore, while A) all of these are correct, D) stands out as a major adaptation that directly influences the surface area to volume ratio.

(04.03 MC) Which of the following is not evidence for the law of conservation of mass during cellular respiration?
The total number of atoms when glucose and oxygen react stays the same when carbon dioxide and water are produced.
C6H12O6 + 6 O2 → 6 CO2 + 6 H2O + energy
The products from cellular respiration are created from the same elements (carbon, oxygen, and hydrogen) that make up the reactants.
Cellular respiration creates an energy molecule when glucose is broken down.
Cellular respiration creates an energy molecule when glucose is broken down doesn't prove the conservation of mass.
Option D.
Explanation:Law of conservation of mass states that mass can neither be created nor be destroyed. And this law holds good for all sorts of chemical reactions except the nuclear reactions.
In case of cellular respiration, one molecule of glucose reacts with 6 molecules of oxygen to produce 6 molecules of carbon dioxide and 6 molecules of water and energy. Now this energy that is produced isn't produced in expense of mass, but in expense of chemical bonds that are present in glucose molecules.
Also if we calculate the number of atoms on each side of the reaction, the number of atoms remain same as well as number of atoms of individual elements also remain same and equal.
Answer:
Cellular respiration creates an energy molecule when glucose is broken down doesn't prove the conservation of mass.

Suppose a cell is placed in a large container of water with a very low solute
concentration.
If a cell is placed in a large container of water with a very low solute concentration water will enter inside the cell and becomes turgid because osmosis will take place.
Explanation:
The solution with low solute concentration is called a hypotonic solution. If a cell is placed in hypotonic solution the water molecules would move inside the cell by the process of osmosis making the cell swell and turgid. The selectively permeable membrane of the cell membrane facilitates osmosis.

Why do you think the word musculoskeletal exists?
and skeletal system have?
Muscles and human skeleton are very much connected with each other.
Explanation:Muscles form one of the 5 systems of our body. They consists of both the skeletal muscles as well as the smooth muscles of our body. While the smooth muscles are the part of the organs, the skeletal muscles are attached with bones either directly attached, or they are attached with the bones by means of tendons. These muscles are formed of cells called sarcomeres and they are the structures which make the bones move. Bones ars like the rods and muscles are like hydraulics. So they are collectively called as musculoskeletal system.
Skeletal system is referred to as the collection of each and every bones of our body which is roughly 206 bones, and their organization in body helping us to stand and move.
2. The ability of an organism to survive and reproduce in its environment is called "fitness." But, it
one version (called the allele) of a trait (like fur color) enables an organism to survive and reproduce
better than other organisms in that same environment, we say that it has a "selective advantage".
Explain how fur color can provide a selective advantage.
Answer:
Traits, like fur colour, can be selectively advantageous for organisms belonging to a certain species.
Fur colours often allow organisms to better hide from their predators
For example, consider a brown fur coloured squirrel and a white fur coloured squirrel. The brown coloured squirrel will be better adapted to hide from its predators as its colour can camouflage with the colour of the woods. The white colour squirrel will not have such a selective advantage and will have more chances to be eaten up by its predator.
Most of the grasshoppers of a particular population are brightly colored.
These bright colors war potential predators that the grasshoppers are
poisonous. One year, several green grasshoppers are produced that blend in
with the surrounding grass and brush.
How might this coloring present an advantage to these grasshoppers?
Explanation:
By NATURAL SELECTION, the green grasshopper in the population will increase with succeeding generations – also meaning the allelic frequency for green color with increase. This is because the grasshoppers blend / camouflage well with their green environment hence are less exposed to their predators that the brightly colored grasshoppers. These grasshoppers are therefore more likely to reach maturity and pass down their genes by reproduction.

the geosphere is the most directly influenced by an external source of energy TRUE OR FALSE
It is FALSE that the geosphere is the most directly influenced by an external source of energy. Rather the geosphere is the most directly influenced by an INTERNAL source of energy.
Explanation:
Due to the enormous pressure of the overlying rock layers, in the core of the earth, their enormous heat energy generated and trapped. This energy is also added up by the radioactivity of radioactive elements deep in the earth. This internal energy source powers the geosphere. This is evident because of the tectonic plate movement that is driven by the convection current of the mantle layer below. This same energy is responsible for other phenomena like volcanic mountains, earthquakes, and even the earth’s magnetic shield.

A.is attractive only
B.acts within nucleus
C.attracts and repels
D.has an infinite range
The area marked X D. has an infinite range Therefore , D. has an infinite range is correct .
In the realm of fundamental forces, both gravitational and electromagnetic forces are of paramount importance.
Gravitational force is the universal force of attraction that exists between any two objects with mass.
According to Newton's law of universal gravitation, every mass in the universe attracts every other mass with a force directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
On the other hand, electromagnetic force encompasses both attraction and repulsion, making it a force with a broader range of effects.
While both forces follow inverse square laws (force diminishes with the square of the distance), the crucial distinction lies in the range. Gravitational force is the weakest fundamental force but has an infinite range.
It acts between all objects with mass regardless of how far apart they are.
Electromagnetic force is immensely stronger but operates over a finite range due to the shielding effect of oppositely charged particles neutralizing their effects at larger distances.
Hence, for the area marked X, the appropriate label is D. has an infinite range.

4. Summarize how a single change at the cellular level can impact the
entire body
A single cellular change can have systemic effects due to the interdependent nature of cellular functions and bodily systems, influencing everything from cell specialization to overall bodily health.
Explanation:A single change at the cellular level can have significant impacts on the entire body due to the intricate network of interactions among cells, tissues, and organs. For example, changes in gene expression due to external stimuli can lead to specialization of cells, which is essential for the proper functioning of tissues and organs. Hormones, which are signaling molecules produced in one part of the body, can affect distant regions, illustrating how a change in one cell type can have widespread effects. Moreover, alterations in feedback mechanisms can have deleterious outcomes, affecting homeostasis and potentially leading to disease states. Even the size and shape of cells play a role in how effectively a cell can intake nutrients and eliminate waste, which is critical to overall bodily health, as seen in conditions like obesity.

8. A student thinks that populations higher in a food chain are larger because they
deplete the populations of organisms lower in the food chain. Using evidence
from this lesson, explain why this student's thinking is incorrect.
In the food chain every time it attains the higher trophic level only ten per-cent of total energy is transferred. The higher trophic level populations in a food chain are larger because the biomass needs to be maintained as there are fewer organisms the biomass is distributed to maintain the equilibrium in the ecosystem.
Explanation:
The less energy passed on to the higher level would cause less population in the higher trophic level and biomass gets distributed so the organisms keep increasing in the size at the higher trophic level.
How is a compound similar to a homogeneous mixture ? How is it different
Similarity between a compound and homogeneous mixture:
The constituent of both homogeneous mixture and compound cannot be distinguished easily.
Difference between a compound and mixture:
The constituents of a mixture are not evenly distributed but the constituents of a compound are chemically bonded in fixed ratio.
The constituents of the homogeneous mixture retain their individual properties but the constituents of a compound do not retain their individual property.
Explanation:
Compounds are pure substances which have definite set of physical and chemical properties.The constituents of a compound are chemically combined and cannot be separated by simple physical methods.The constituents of compound lose their individual properties.For example , Hydrogen and Oxygen combine to form water. But the properties of water are totally different from both the constituent. Here, hydrogen and oxygen are gases which combined covalently to produce a substance which is liquid which definite physical and chemical properties.A mixture has constituents that are not chemically combined. Each individual constituent retains its individual property in a mixture.For example , in a sugar solution the sugar does not lose its sweetness and water is liquid state. The solution thus tastes sweet. Secondly, both the constituents can be separated easily by evaporation or crystallization.Compounds and homogeneous mixtures both have uniform compositions, but compounds have chemical bonding that creates new properties, whereas homogeneous mixtures retain the properties of their individual components and the ratio of components can vary.
Explanation:A compound is similar to a homogeneous mixture in that both have a uniform composition throughout. Homogeneous mixtures, such as a sugar solution in water, have the same ratio of components throughout, much like compounds have a consistent ratio of elements. However, the components in a homogeneous mixture retain their own properties and can be physically separated, whereas in a compound, the elements chemically combine to form a substance with new properties. For example, sodium chloride (table salt) is a compound formed from the elements sodium and chlorine and has different properties from either element alone.
Furthermore, a compound is defined by a fixed composition with elements combined in a specific ratio, whereas the composition of a homogeneous mixture can vary, like different concentrations of sugar in water. If the mixture of tea and sugar has too much sugar that it cannot all dissolve, the mixture would transition from homogeneous to heterogeneous, with the sugar visible at the bottom of the cup.
A species is a group of organisms capable of mating and producing offspring, and speciation is the process of forming a new species.
One way a new species may form is by geographic isolation. This occurs when members of a population are physically separated, for example, by a river, or a desert.
After the separation the two populations, responding to different conditions, will adapt differently, and so their evolutionary paths will

A certain population of bluebirds eats spiders as a major food source. Which of the following ecosystem changes would impact this population of bluebirds the most?
Answer:
The correct option is an increase in the spider and insect population.
Explanation:
As bluebirds feed on spiders and their major source of food, hence an increase in the population or decrease in the population of the spiders will heavily affect the population of the bluebirds.
If the population of insects and spiders increases, there will be enough food source available for the bluebirds due to which their population will grow in size. On the other hand, if the population of spiders decreases, then there will be competition for food and the bluebirds population will also start to decrease.
The bluebird population would be most impacted by an increase in the spider and insect population, as it directly increases their food supply. Therefore the correct answer is C) an increase in the spider and insect population.
The correct answer is C) an increase in the spider and insect population. A rise in the spider and insect population provides more food resources for the bluebirds, directly benefiting their population. A decrease in daylight hours might affect them but not as drastically, while changes in rabbit and fish populations are irrelevant. These changes highlight how food availability can directly affect species populations.
A) a decrease in the number of daylight hours could affect the bluebirds' hunting behavior and reproduction patterns but not as significantly as their immediate food supply.B) a decrease in the rabbit population is largely irrelevant to bluebirds since rabbits are not a food source for them.D) an increase in the fish population is also irrelevant as bluebirds do not typically prey on fish.Environmental changes like these can impact species populations directly or indirectly through factors such as food resource availability and predator densities, as noted in ecological studies.

O
A. Single strands of DNA
O
B. Two copies of a DNA molecule
C. Complementary strands of mRNA
OD. Proteins
Answer:
the right answer is option D. proteins.
Explanation:
The molecule that results from translation is protein -- or more precisely, translation produces short sequences of amino acids called peptides that get stitched together and become proteins. During translation, little protein factories called ribosomes read the messenger RNA sequences.
I hope this is the answer. I'm not sure. but I think, it is.
The final product of translation is proteins. During translation, the information encoded in messenger RNA (mRNA) is used to synthesize a specific protein.
Ribosomes, along with transfer RNA (tRNA) molecules carrying amino acids, read the mRNA sequence in groups of three nucleotides called codons.
Each codon corresponds to a specific amino acid, and as the ribosome moves along the mRNA, it links the amino acids together to form a polypeptide chain.
Once the polypeptide chain is complete, it undergoes further processing and folding to become a functional protein. Therefore, the correct option is D. Proteins.

Cells transport molecules into the cell in many different ways. One method is through endocytosis, shown in the model. In endocytosis, the cell brings specific molecules it needs, finding fluid, into the cell. Why does the structure of the plasma membrane make this type of transport necessary for fluids?
Yes structure of membrane is necessary to transport these fluids.
Explanation:The method of transport of fluids into the cells by using the plasma membrane is called pinocytosis or endocytosis. In this method, first the cell finds a fluid that is suitable to be taken inside the cell for further necessities like nutrition, immunity etc. Then the cell produce some pseudopodia which covers up the fluid. Then a depression in cell membrane is seen engulfing the fluid and the margins of that depressed part approximates, resulting in punching off the portion of cell membrane into the cell, forming a secondary lysozome. This is seen in figure.
Without the help of the plasma membrane, the engulfing of the fluid by the cell is impossible, so plasma membrane structure is important for endocytosis.
Answer:
While the heads of the phospholipid structure attract water, the tails are hydrophobic. The model shows how the hydrophilic section folds around the fluid molecules to bring them into the cell so they don’t need to pass through the hydrophobic tails.
