I believe animals that possess homologous structures probably evolved from the same ancestor. Homologous structures are similar because of common ancestry. A homologous structure is an example of an organ or bone that appears in different animals, underlining anatomical commonalities demonstrating descent from a common ancestor.
Answer:
Option C
Explanation:
For chagarff's rule, it clearly states that DNA from any cell of any organisms be it prokaryotes or eukaryotes should have the basic 1 (purine): 1 (pyrimidine) ratio. Particularly, amount of adenine should be equal to thymine, and guanine equal to cytosine. This is in particular reference to organisms that have double stranded DNA.
The correct answer is (a.) Its spindle-shaped cells allow it to do smooth muscles. The structure of the cardiac muscles which is spindle-shaped is very important for the heart to withstand the stretching of the muscles during the contractions. Also for its smooth surface which is very important to prevent any possible blood clot during circulation.
1st conclusion: Organisms inherit two copies of each gene, one from each parent.
2nd conclusion: Organisms donate only one copy of each gene in their gametes.
Thus the two copies of each gene segregate or separate during gamete.
Hope this helpedXD
