What contributes to waste management by recycling metabolic products and converting toxic substances into less toxic ones
kompoz [17]

The kidneys contribute to waste management by recycling metabolic products and converting toxic substances into less toxic ones.

Kidneys are an important organ of animals as they provide a channel for the disposal of body waste and simultaneously regulate the balance in the level of salt and water in the body.

Kidneys work as microfilters that are capable of eliminating dissolved and suspended forms of ammonia, uric acid, urea, creatine, creatinine, amino acids, excess salts, and water along with proper disposal of organic waste which altogether constitutes the metabolic waste of the body. These substances before being finally excreted from the boy undergo a last round of reabsorption.

In the Hardy-Weinberg equation shown below, p is the frequency of the dominat allele, and q is the recessive allele
Lemur [1.5K]

Answer:

Option D- frequency of the heterozygous qenotype

Explanation:

In the Hardy-Weinberg equilibrium , 2pq stands for the genotype frequency of heterozygotes (Aa) in a population at the state of equilibrium. dominant homozygotes (AA) is represented by the p-square and q- square represents the recessive homozygotes (aa) frequency. p represents the allele frequency of A Allele and q stands for the allele frequency of the allele a. Summation of the terms gives an equal to 1(100%). The sum of all of these terms is always equal to due to the fact that the 3 frequencies in the equation are the available or possible allele combinations.

Hardy-Weinberg is relevant for it helps us in comparison of a population's actual genetic structure as time goes on along with the genetic structure we are to get if really population was in Hardy-Weinberg equilibrium state that is population was not evolving.
