Answer:
A. These homologous structures indicate that these four organisms all share a common ancestor.
Explanation:
Homologous structures mean the organs will have similar structure, but not necessarily function (human arm vs whale's flipper). While analogous structures are similar in function but not structure (wings of an airplane vs wings of a bird). Since the question states that they are similar in skeletal structure, we know they must be homologous structures, thereby eliminating B and C. D is not a choice because the question does not provide anything about the order of evolution. Therefore the answer is A. These homologous structures indicate that these four organisms all share a common ancestor.

Explanation:
The statement that is true about homologous chromosomes of a pair is that homologous pair have the same genes at the same location (loci), but will possibly have different alleles.
<h3>What are homologous chromosomes?</h3>
Homologous chromosomes are set of chromosomes that possess similar but non-identical genes.
Homologous chromosomes are from each parent of an organism i.e. male and female parent.
The homologous chromosomes is responsible for the diploid state of an organism, however, it becomes separated during the anaphase 1 stage of meiosis.
Therefore, the satement that is true about homologous chromosomes of a pair is that homologous pair have the same genes at the same location (loci), but will possibly have different alleles.

Answer:
The Galapagos cormorant has vestigial wings that don't help it to fly or swim, though the birds still dry them off in the sun after they get wet, just as if they would if they still could use them to fly. This species diverged into a flightless bird about 2 million years ago.
