Answer:
With respect to genetic information, it is true that a gene is a section of DNA and is found on a chromosome in the cell's nucleus.
Explanation:
DNA contains all the genetic information that determines the morphological and functional characteristics of living beings.
The structure of DNA contains specific sequences of 4 nitrogenous bases, whose extension constitutes the coded genetic information. A chromosome is formed by a DNA molecule, and the<u> </u><u>genes</u><u> contained in the chromosome locus are sequences of nucleotides coming from fragments of that same DNA</u>.
All the genetic information —DNA, chromosomes and genes— is located in the cell nucleus.

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.
