Answer:
b. successfully interbreed
Explanation:
At first, these two kinds of warblers are described as two different species because of their ranges. However, if they are described now as a single species, that means that they can mate between them. A species, in general terms, is defined as a reproductive unit of organisms, so if a group of organism can produce fertile progeny, it is called "species".
Living in the same area, or having an identical appearance are not criteria to call a group of individuals "species". So, options a and c are wrong.
Option "d. are merging to form a single species" implies than before, the two types of warbles were different species, and now they formed a new single species. This is not what the rubric says. In this example, the two warbles always have been a single species, but before they were wrongly categorized, probably because it wasn't known that they were able to interbreed.
<h2>Answer:</h2><h3>Coarctation of the aorta.</h3><h2>Explanation:</h2>
This is a medical condition in which the aorta, the largest blood vessel that leaves the heart, contracts. This blood vessel is tasked with carrying oxygenated blood from the heart to the rest of the body. Also known as Aortic narrowing, this medical condition can be identified by symptoms like tachypnea, diminished femoral pulses, and poor lower body perfusion.
There are five basic Hardy-Weinberg assumptions: no mutation, random mating, no gene flow, infinite population size, and no selection. If the assumptions are not met for a gene, the population may evolve for that gene (the gene's allele frequencies may change).
Answer:
phenotypes
a. genotypes
A person's genotype refers to their genetic blueprint and it is fixed at conception. While A person's phenotype refers to the physical expression of their genetic code which can be altered by biological and environmental factors
