B. Allele frequencies change randomly each generation

Answer 2

Answer:

B

Explanation:

Genetic drift is the alteration of different genotypes in a small population which can cause individuals and organisms getting wiped out, not being able to reproduce, and disappearance. Allele frequencies change randomly each generation in a gene pool (collection of different genes present in a particular population: species in this gene pool have a choice to leave the gene pool or die out).

Ca(OH)2 is added to a large beaker of water. How is the solution different from the original water? The solution turns blue litmus to red. The solution turns phenolphthalein pink. The solution has more hydrogen ions. The solution has fewer hydroxide ions.

Answers

When Ca(OH)₂ is added to a beaker of water the solution would turn phenolphthalein pink. thus option B is correct.  

What is phenolpthalein?

Phenolphthalein is a common indicator and is only pink when in basic solutions.  

By adding calcium hydroxide, you are turning the solution into a basic solution since the concentration of OH⁻ ions is going up and therefore any phenolphthalein in solution would turn pink.

what is meiosis?

Meiosis, also called reduction division, division of a germ cell involving two fissions of the nucleus and giving rise to four gametes, or germ cells.

The process of meiosis is characteristic of organisms that reproduce through fusion. Such species have in the nucleus of each cell a diploid (double) set of chromosomes, consisting of two haploid sets (one inherited from each parent). These haploid sets are homologous—i.e., they contain the same kinds of genes, but not necessarily in the same form.
