Diffusion is not active and instead a form of passive transport. So the correct option is option C.

Because diffusion is a non-electrical process, small particles move faster than larger ones. For example, molecules such as oxygen, CO2, and glucose move through cells.

Active transport involves moving molecules from a low-concentration region to a high-concentration region. In contrast to diffusion, active transport involves moving molecules against a concentration gradient.

The term “active” refers to the fact that transport is energy-dependent. Active transport is energy-intensive, whereas diffusion is energy-free.

The two types of vascular tissues in celery are the xylem and phloem.

The two types of vascular tissues in celery are the xylem and phloem. The xylem is responsible for transporting water and minerals from the roots to the leaves, while the phloem is responsible for transporting sugars and other organic compounds from the leaves to the rest of the plant.

In a cross-section of celery under the microscope, the xylem and phloem can be seen as long, cylindrical structures located in the center of the stem. The xylem appears as a series of small, interconnected tubes with thick walls, while the phloem appears as larger, thin-walled tubes.

In addition to the vascular tissues, the ground tissue in celery can also be observed in a cross-section under the microscope. The ground tissue makes up the majority of the plant and is responsible for functions such as photosynthesis, storage, and support. In celery, the ground tissue appears as a thin layer surrounding the vascular tissues and is made up of cells with thin cell walls and large central vacuoles.

Overall, the cross-section of celery under the microscope reveals the two types of vascular tissues, xylem and phloem, as well as the ground tissue which surrounds them.

If both organisms are pigmented, they must both be carrying at least one dominant P allele.

When they produce a non-pigmented offspring, that means that each parent passed on a recessive p allele to their offspring, resulting in the offspring having two recessive p alleles. Therefore, both pigmented parents are heterozygous for the P allele (Pp).
When the Pp parents mate again, there is a 25% chance that their offspring will inherit two dominant P alleles (PP), a 50% chance that they will inherit one dominant P allele and one recessive p allele (Pp), and a 25% chance that they will inherit two recessive p alleles (pp). Therefore, there is a 75% chance that their next offspring will be pigmented (either PP or Pp), and a 25% chance that they will be non-pigmented (pp).

The layer of soil closest to the surface is the topsoil. Topsoil is the uppermost layer of soil that is rich in organic matter and nutrients, making it the most fertile layer of soil. option b is correct.

It typically ranges from 2 to 8 inches in depth and is formed by the accumulation of decomposed plant material and other organic matter over time. Topsoil is crucial for plant growth as it provides the necessary nutrients and water for plants to thrive.

Beneath the topsoil is the subsoil layer, which is typically made up of larger particles and is less fertile than the topsoil. The parent rock, which is the rock layer from which the soil originated, is located beneath the subsoil layer and can be hundreds or thousands of feet below the surface. The parent rock influences the properties of the soil layers above it, such as their texture, mineral content, and drainage capabilities.

If the primary producer absorbed 845 calories from the sun, 84.5 calories can be able to store if they ate the consecutive organism.

The place an organism holds in a food web determines its trophic level. A food chain is a series of living things that consume other living things and may eventually consume themselves.

An organism's trophic level is determined by how far along the food chain it is.

Energy is lost as metabolic heat when animals from one trophic level are ingested by species from the next level, hence energy diminishes as it goes up the food chain.

10% of energy, according to Lindeman's 10% law, is the maximum amount that can be transferred.

As per this law, 10 % of 845 calories will be transferred to consecutive organism, i.e., 84.5 calories.

Thus, 84.5 calories each trophic level be able to store.

The cell's concentration of amino acids is least altered.

These tRNAs transport amino acids to the ribosome during translation where they combine with their complimentary codons. The formed amino acids are then linked together as the ribosome advances along the mRNA molecule in a ratchet-like process, assisted by its resident rRNAs.

To build the desired protein, the amino acids must be brought and placed in the proper positions by tRNA. Proteins and rRNA make up the ribosomes. Each ribosome is composed of two subunits. They "clamp" the mRNA in place so that the coding can be read and translated.

Answer: A

Explanation:

Valinomycin acts as an **uncoupler** rather than an inhibitor of oxidative phosphorylation.

Oxidative phosphorylation is the process by which ATP is generated in mitochondria through the coupling of electron transport and proton pumping across the inner mitochondrial membrane.

This proton gradient is then utilized by ATP synthase to produce ATP.

Valinomycin is an ionophore that facilitates the transport of potassium ions (K+) across the inner mitochondrial membrane.

By allowing the free movement of K+ ions, valinomycin disrupts the proton gradient that is essential for ATP synthesis. As a result, several effects are observed:

1. The yield of ATP decreases because the uncoupling disrupts the coupling of electron transport and ATP synthesis.

2. The rate of O2 consumption increases as the electron transport chain continues to function but without ATP synthesis occurring.

3. Heat is released as the energy that would have been used for ATP synthesis is dissipated.

4. The pH gradient across the inner mitochondrial membrane increases because the movement of protons (H+) is decoupled from ATP synthesis.

Overall, valinomycin disrupts the coupling of electron transport and ATP synthesis, leading to decreased ATP production, increased O2 consumption, heat release, and an increased pH gradient, which are characteristic effects of an uncoupler of oxidative phosphorylation.

An example of a part of the hydrosphere that is far away from me is the Arctic Ocean. The Arctic Ocean is located in the polar region and is covered by a layer of ice for most of the year.

Water in the Arctic Ocean can travel through the water cycle by a process called evaporation. As the sun shines on the Arctic Ocean, it can cause some of the water on the surface to evaporate, turning it into water vapor. This water vapor can then travel through the atmosphere and condense into clouds as it cools down. As the clouds move over different regions, they can release precipitation, which can fall as rain or snow depending on the temperature.

If the water that originated from the Arctic Ocean falls as snow, it could accumulate and eventually form glaciers or ice caps in higher elevations. As the temperature warms, the snow and ice can melt, turning into liquid water. This water can then flow downhill and eventually reach rivers, lakes, and oceans, where it can evaporate again and continue the water cycle.

If the water that originated from the Arctic Ocean falls as rain, it could end up in a puddle where I live if it lands on the ground and doesn't flow into a body of water. As the temperature warms, the puddle can evaporate and turn into water vapor, which can then become part of the atmosphere and continue the water cycle.

Overall, water in the hydrosphere can travel through different states (solid, liquid, gas) as it moves through the water cycle and can end up in different regions, including where I live, through precipitation and other natural processes.
