During meiosis, each pair of alleles on the homologous chromosomes sorts independently from all other pairs of alleles. This statement corresponds to the law of independent assortment.
What does the law of independent assortment say?
Mendel's Second Law, also known as the Law of Independent Segregation, states that the factors (alleles) for two or more traits are independently distributed during gamete formation and combine at random.
So in this case, each pair of alleles on the homologous chromosomes sorts independently from all other pairs of alleles represents Mendel's second law.

Which of the following is a characteristic of a population that is in Hardy- Weinberg equilibrium? A. The gene pool gets smaller in each generation. B. The alleles mutate in every generation. C. There are equal amounts of immigration and emigration. D. The frequency of each phenotype does not change.
The gene pool gets smaller in each generation, which is the characteristic of a population that is in Hardy- Weinberg equilibrium. The correct option is A.
What is a gene pool?The gene pool encompasses all of a species' genetic diversity. The gene pool's size can change. When organisms have mutations that are passed down to the next generation, the gene pool expands.
When all of the organisms carrying a particular allele die before having offspring, the gene pool shrinks.
Thus, the correct option is A.

How is the law of conservation of mass applied to ecology?
In ecology, the law of conservation of mass is applied by the principle of taking energy from the lower trophic levels and passing it to the higher trophic level by any means.
What is the law of conservation of mass?The law of conservation of mass states that the actual mass in an ecosystem is neither created nor destroyed. Overall remains constant in a system.
In ecology, it illustrates that when an organism is ingested by other organisms, its mass is conserved. Some of the organisms may also be dependent on the waste products like urine and feces to make proteins and other compounds.
Therefore, the energy or mass is neither lost in any form. It simply is taken by other organisms through any means.
