D. It provides buoyancy to a fish.
This air pocket is known as the swim bladder, and also called air bladder. This is a buoyancy organ possessed by most bony fish. The air bladder is located in the body cavity and is derived from an out pocketing of the digestive tube.

Answer:Genetic drift is the process where there are random fluctuations in the gene frequencies within a population. Which of these populations would most likely experience genetic drift?
Explanation:Genetic variation describes naturally occurring genetic differences among individuals of the same species. This variation permits flexibility and survival of a population in the face of changing environmental circumstances. Consequently, genetic variation is often considered an advantage, as it is a form of preparation for the unexpected. But how does genetic variation increase or decrease? And what effect do fluctuations in genetic variation have on populations over time?hen a population interbreeds, nonrandom mating can sometimes occur because one organism chooses to mate with another based on certain traits. In this case, individuals in the population make specific behavioral choices, and these choices shape the genetic combinations that appear in successive generations. When this happens, the mating patterns of that population are no longer random.
Nonrandom mating can occur in two forms, with different consequences. One form of nonrandom mating is inbreeding, which occurs when individuals with similar genotypes are more likely to mate with each other rather than with individuals with different genotypes. The second form of nonrandom mating is called outbreeding, wherein there is an increased probability that individuals with a particular genotype will mate with individuals of another particular genotype. Whereas inbreeding can lead to a reduction in genetic variation, outbreeding can lead to an increase.
Answer:
The given characteristics can be shown by Enzymes.
Explanation:
- Enzymes are substances, mostly proteins, that helps in increasing the speed or rate of a biochemical reaction (conversion of substrate to product) by reducing the activation energy barrier of the reaction.
- The enzymes which are made up of proteins have an specific location or region inside them which is called the Active Site.
- The biochemical reaction occurs at this active site.
- The specific substrate molecule(s) comes and associated with the active site of the enzyme, mostly by means of non-covalent interactions.
- By means of amino acid side chains (which have a definite pKa) the exact environment (oxidising or reducing) required for the chemical reaction to occur is maintained by the enzyme at its active site.
- After associating with its substrate(s) the enzyme undergoes certain conformational changes in order to position the substrate(s) in the correct orientation such the biochemical reaction can occur.
- After the products are formed, the enzyme further undergoes some conformational changes to release them.
- Enzymes are similar to transport proteins because:
- When the concentration of substrates is far more than that of the available enzymes molecules, then the enzymes would get saturated with substrates, like the transport proteins.
- The enzymes are highly specific for their substrates like the transport proteins.
- The enzymes undergo conformational changes during the biochemical reaction like the transport proteins.
- Both the rate of enzymatic reaction and membrane transport is regulated by the cell.
