Which three elements make up most of the human body?

The two structures that play crucial roles in energy production for a plant cell are the mitochondrion and chloroplast.

Mitochondria are the powerhouses of the cell, conducting cellular respiration to convert nutrients into adenosine triphosphate (ATP), the cell's primary energy currency.

On the other hand, chloroplasts are responsible for photosynthesis, a process where they capture light energy, convert it into chemical energy, and synthesize glucose.

The nucleus contains genetic information but is not directly involved in energy production.

Cytoplasm is a gel-like substance that houses cellular components, but energy production occurs primarily in the mitochondrion and chloroplast.

Answer:

atmospheric pressure

Explanation:

hope this helps sweetheart

The correct answer is option A. Barometers are instruments used specifically to measure atmospheric pressure.

So, barometers are uniquely designed to measure atmospheric pressure, which helps in weather forecasting and understanding weather patterns. They are sensitive to these pressure changes and are essential tools in meteorology and weather forecasting.

Why other options are not correct:

Option B is incorrect because temperature is measured using thermometers, which are designed to detect and quantify thermal energy or heat. Thermometers use various principles such as expansion of liquids, gases, or digital sensors to determine temperature.

Option C is incorrect because humidity refers to the amount of moisture or water vapor present in the air. It is measured using instruments called hygrometers or psychrometers, which analyze the moisture content in the atmosphere.

Option D is incorrect because wind speed is measured using instruments called anemometers. Anemometers detect and quantify the speed of wind currents, which is crucial for meteorological purposes and environmental monitoring.

Explanation:

Three.

Photosynthesis produces glucose and O2 from inorganic CO2, light energy and water.  This occurs in distinct steps: 1) light fixation,  2) electron transport and NADPH production 3)  ATP generation, then 4) carbon fixation and carbohydrate production.

6CO2 + 6H20 + (energy) → C6H12O6 + 6O2

Further Explanation:

Photosynthesis is a chemical process, essential to plant and other primary producers producing energy. As oxygen is emitted, energy in the form of glucose molecules is created from light, water, and carbon dioxide. It happens in several complicated stages, photosynthesis is a speed-limited process, depending on several factors including concentration of carbon dioxide, ambient temperature and light intensity; energy is extracted from photons, i.e. light particles, and water is used as a reduction agent. It occurs in the thykaloids, where pigment molecules live like chlorophyll.

Photosynthesis occurs in several complex steps and is a reaction of a small duration, depending on several fa factors including carbon dioxide concentration, ambient temperature and light intensity; the energy is retrieved from photons, I.e. particles of light, and water is used as a reducing agent. Water supplies the chlorophyll in plant cell with replacement electrons for the ones removed from photosystem II.

Answer:

It's five

Explanation:

I just took the test

Vertical farming is the best technique for teaching the benefit of sustainable farming in an urban New York City elementary school due to its space efficiency and the hands-on learning experiences it can provide to students. So the correct option is the fifth option.

The best technique to employ in teaching elementary school students in New York City the benefit of sustainable farming could be vertical farming. This method is well-suited to urban environments where space is limited. Vertical farming involves stacking layers of plants on top of each other and growing them indoors, often using hydroponic or aeroponic systems. This type of farming conserves space and resources, reduces transportation costs and emissions by growing food close to where it will be consumed, and can provide fresh local produce year-round.

While options like urban greenhouses, precision agriculture, and aqua farming are also methods of sustainable farming, vertical farming is often more practical and visible for an urban school setting. It also serves as an excellent educational tool to demonstrate sustainable practices and innovative agricultural technology to students.

Moreover, this technique doesn't require large tracts of land and can be implemented on a small scale within the school itself, offering students hands-on learning experiences.

Answer:

oxygen in the solution will naturally diffuse into the cell.

Explanation:

Cells require oxygen for cellular respiration to occur. When a cell is places in a solution having oxygen dissolved in it, The concentration of the oxygen outside the cell will be more as compared to the concentration of oxygen inside the cell. As a result, the cell will take up oxygen by the process of diffusion. Diffusion is the movement of particles from a higher concentration to a lower concentration along a concentration gradient.

Answer:

Climate and soil composition

Explanation:

Scientists classify soil based on criteria such as soil profile, climate, soil composition, bedrock, and soil horizon, each contributing to defining soil's properties and capabilities.

Scientists consider several criteria when they classify soil. These criteria include soil profile, climate, soil composition, bedrock, and soil horizon. The soil profile is composed of distinct layers known as horizons, such as the O, A, B, and C horizons, each with specific characteristics that play different roles in nutrient cycling, water retention, and support for plant life. The climate influences soil formation by affecting weathering patterns, biological activity, and moisture content.

Soil composition is shaped by the type of parent material and influences the soil's physical and chemical traits. Lastly, the soil horizon refers to the individual layers within the soil, like topsoil (A horizon) and subsoil (B horizon), each distinguished by its properties and composition. The underlying bedrock can become the parent material for soil formation affecting the soil through its mineral content and by providing a base for the development of the soil's upper layers.

Answer:

It allowed scientists to clearly communicate with each other about different organisms.

Explanation:

Carl Linnaeus was a Swedish Botanist who is known for devising the system of classification for organisms and bringing forward the system of binomial nomenclature. Binomial nomenclature can be described as a method by which a scientific name is assigned to every organism based on their genus and species name.

This method is beneficial for scientists so that they can communicate with each other about different organisms. As scientists belonging to different regions had different common names for an organism, binomial nomenclature made possible for scientists to communicate bu using specific scientific names.

Explanation: Example, breeding a shih tzu and a poodle concludes to a new breed which is a p tzu. Sounds funny, but true. Evolving the dogs world even further.

Final answer:

A breeder might produce a new dog breed with long ears and a snub nose through artificial selection, repeatedly breeding dogs with these traits. This process mirrors natural selection and provides evidence of evolution, as it shows how selective pressures can lead to the development of new traits within a population.

Explanation:

A breeder aiming to produce a new breed of dog with long ears and a snub nose would use a process known as artificial selection. This involves selecting dogs that exhibit long ears and a short snout and breeding them together. Over multiple generations, by consistently choosing and mating individuals with desired traits, these characteristics would become more pronounced within the breed due to the inheritance of these traits. This type of selective breeding is what led to the variety of dog breeds we see today, from the tiny Chihuahua to the large Great Dane, all derived from a common ancestor related to wolves.

The production of a new breed through selective breeding is evidence of evolution because it demonstrates how selective pressures, whether natural or artificial, can lead to the development of new traits within a population. What starts as slight variations within a gene pool can be magnified over time into significant differences, mirroring the process of evolution in nature, albeit at a much faster and directed pace due to human intervention.

The famous Silver Fox Experiment conducted by Dmitri Belyaev and Ludmilla Tutt showed that selecting for behavioral traits such as docility in wild foxes not only resulted in tamer foxes but also produced physical changes such as shorter snouts and different coat patterns. This experiment provided strong evidence for how selection can lead to changes in morphology as well as behavior, further supporting the concept of evolution through selected traits.

Explanation:

A drop in blood pH of 0.2-0.3 can cause seizures, comas, and even death. Similarly, a small change in the pH of seawater can have harmful effects on marine life, impacting chemical communication, reproduction, and growth. The building of skeletons in marine creatures is particularly sensitive to acidity

An effect which the increase in the ocean acidity most likely have on marine organisms is the higher acidity could make it harder for many organisms to build their shells and skeletons. Thus, the correct option is A.

As the ocean acidification increases, the amount of available carbonate ions (CO₃²⁻) bonds with excess hydrogen, thus resulting in fewer carbonate ions being available for calcifying organisms to build and maintain their shells, skeletons, and other calcium carbonate structures in the marine organisms.

Ocean acidification is also called as osteoporosis of the sea. Ocean acidification can create the conditions which results into eating away the minerals which are used up by oysters, clams, lobsters, shrimp, coral reefs, and other marine life to build their shells and skeletons for survival.

Therefore, the correct option is A.

Answer:    

The period focused on self-actualization and one's ability to accept what is going on in one's life. The earliest Renaissance literature appeared in Italy in the 14th century; Petrarch, Machiavelli, and Ariosto are notable examples of Italian Renaissance writers.

Explanation:

Final answer:

Renaissance writers created works that reflected the human experience, often incorporating classical themes and promoting harmony and beauty. They explored love, religious faith, and humanistic themes, and the rise of genres such as the Gothic tale marked literary innovation. The writings of Dante, Petrarch, and their contemporaries were key in shaping this transformative period.

Explanation:

Renaissance Writers and Their Subjects

Renaissance writers were deeply influenced by the catastrophes of the 14th century such as the Hundred Years' War, the Black Death, and widespread famines, which paradoxically helped set the stage for the later flourishing of the arts known as the Renaissance. This period is characterized by a revival of interest in the classical knowledge of Greece and Rome, humanist values, and artistic innovation. Dante Alighieri, Petrarch, and Giovanni Boccaccio were among the early figures whose works laid the groundwork for Renaissance thought and literature.

Dante and Petrarch, operating during times of economic recession and social instability, focused on the human experience, integrating elements of classical antiquity with contemporary concerns. Petrarch, particularly, advocated for the use of clear, classical Latin and imitating the style of ancient Roman writers. In the midst of recovery from plague and war, there emerged a wealthier population with a demand for luxury goods, including literature and arts, which stimulated the creation of a new merchant class and patronage for writers and artists. As a result, authors during this time wrote on a range of topics, including human relationships, religious faith, and philosophical inquiry into the nature of love and beauty. Their works often stressed harmony and beauty, two pillars of Renaissance aesthetics.

Emerging out of this context were the Gothic and mystery tales with Edgar Allan Poe and Mary Shelley being notable contributors to this genre. Mannerism later emerged as a reaction against the earlier Renaissance styles, rejecting harmony and ideal proportions for more exaggerated and emotionally expressive forms. The renewed interest in classical Greek philosophy and literature aided Renaissance writers in exploring humanistic themes, with the church providing significant patronage for many works.
