These is characteristic of the photic zone of a freshwater biome are the presence of algae as Algae are found in all types of water, including salt water, fresh water, and brackish water (a mixture of salt and fresh water). Algae that live in water are divided into two types: algae and phytoplankton.

Algae are large plants made up of many cells, while phytoplankton are small single-celled plants. Photosynthetic algae called phytoplankton live in the photozone. Zooplankton - small free-floating animals - feed on phytoplankton.

This is the first step in many aquatic food webs. Below the light zone is a dark non-light zone where photosynthesis is not possible. Freshwater benthic algae are found in the photozones of streams and rivers, lakes, and wetlands.

All cytoskeletal elements have specific functions and structural characteristics that make them susceptible to different types of damage or disruption. However, the microtubules are considered the most susceptible cytoskeletal element. Microtubules are flexible, hollow tubes made up of a protein called tubulin. They are responsible for maintaining cell shape, cell division, and organelle movement. Because of their dynamic nature, microtubules are more susceptible to damage caused by environmental factors such as temperature changes, pH changes, and exposure to chemicals. Additionally, microtubules are also more susceptible to disruption caused by certain drugs and toxins that target tubulin, such as the chemotherapy drug taxol.

The expressed allele when no dominant allele is present in Recessive allele.

In general, Recessive alleles are expressed in certain condition when their is no dominant allele  present. But when we talk about  s.e.xually reproducing organisms, each of then will contain two alleles for every gene (one from each parent). This pair of alleles is also known as genotype that is responsible for determining the organism's phenotype.

Hence , Recessive alleles can only be expressed when both parents have recessive alleles for the given trait . on the other hand Dominant alleles are always expressed, regardless of what the other allele is present. If a person carries one dominant allele and one recessive for any trait, it is termed as a carrier.

Answer: A. when the water current slows down.

Explanation:

When a water current slows down, the force of the water is not strong enough to continue carrying the sediment, so it drops the sediment and deposit it. The slower the flow, the larger the particles that can be carried and eventually deposited. This is why river deltas, for example, are formed where a river enters a body of water and the flow slows down, allowing sediment to build up and create landforms.

All of the following are true of antibodies EXCEPT that they destroy virus-infected cells because antibodies are bind to pathogens and antigens.

Antibodies remove foreign chemicals from the body by attaching to particular antigens. The variable section of the antibody binds to the pathogen when it gets into the body as a pathogen, such as a hazardous bacteria or virus, and ultimately causes a number of activities, such as the pathogen's elimination.

Viruses and intracellular bacteria attach to particular molecules on the surface of the target cell in order to enter the cell. This can be avoided as the pathogen is said to be neutralised by antibodies that bind to it. Antibodies' ability to neutralise bacterial toxins is crucial for preventing their entry into cells.

An organism can acquire new features as a result of gene changes that change transcriptional activity or protein function. If a characteristic is present, a genetic variation is more likely to be handed down .

Almost every cell in an individual's body harbors these hereditary mutations during the course of their lifespan. Hereditary mutations include conditions including cystic fibrosis, sickle cell anemia, and hemophilia. Additional mutations might develop on their own over a person's lifespan. They are referred to as sporadic, spontaneous, or new mutations.

Genetic variations that are advantageous to an individual's survival are passed on through reproduction under natural selection.

When the rate of respiration in a plant is greater than the rate of photosynthesis, the plant will release more volume of carbon dioxide (CO2) into the environment than usual.

This is because respiration is the process by which plants convert stored energy, such as sugars, into usable energy for growth and survival. During this process, CO2 is released as a byproduct. Overall, when the rate of respiration in a plant is greater than the rate of photosynthesis, the plant will release more CO2 than it is able to take in through photosynthesis, leading to a net loss of CO2 for the plant. This may not be favorable for the plant's growth and survival in the long term.

Photosynthesis, on the other hand, is the process by which plants convert light energy into chemical energy, using CO2 and water to produce oxygen and glucose. When the rate of respiration is greater than photosynthesis, the plant is using up more energy than it is able to produce, leading to a net loss of CO2. This can occur under conditions such as low light intensity, high temperatures, or water stress.

When a tall plant (TT) in pea is crossed with another tall plant (TT), the probability of obtaining a dwarf plant is 0%.

Both parents are tall plant (TT) which are homozygous dominant for the trait of plant height. This means that they both have two copies of the allele that codes for tall plant height (T). Since the allele for tall plant height is dominant, it masks the presence of any allele for short plant height (t). In this cross, both parents only have the allele for tall plant height, so all of their offspring will also have the allele for tall plant height.

This can be represented in a Punnett square shown in the attached picture. As you can see in the Punnett square, all the offspring will be TT, and will be homozygous dominant for the trait of plant height and will exhibit the dominant trait (tall plant height).

Therefore, all the offspring will be tall and none of them will be dwarf.
