Whales have pelvic (hip) bones, which are evolutionary remains from when their forefathers walked on land about 40 million years ago. Common belief has long assumed that such bones are merely vestigial, slowly withering away like human tailbones. Thus option C is correct.
<h3>What is the new research from USC and the Natural History Museum of Los Angeles County (NHM) has to say ?</h3>
New research from USC and the Natural History Museum of Los Angeles County (NHM) contradicts this belief, discovering that not only do those pelvic bones have a role, but their size and perhaps shape are impacted by sexual selection processes.
Therefore, small, shrunken hip bones of whale are no longer beneficial for survival and are considered vestigial. So, the best option is C among the other options available. Thus option C is correct.

Answer:
The percentage of other bases are: Thymine = 35%, guanine = 15% and cytosine = 15%.
Explanation:
There are four bases in DNA molecules, the bases are adenine, thymine, guanine and cytosine. The quantity of adenine and thymine are always equal, so also, the quantity of guanine and cytosine are always equal. Based on the information given in the question, Adenine = 35%, this implies that thymine too is 35%. The two bases added together give 70% , leaving only 30% for guanine and cytosine. Cytosine and guanine will share this equally and so each one of them will have 15%.
Answer:
antigens
Explanation:
Specific immune responses are triggered by antigens. Antigens are usually found on the surface of pathogens and are unique to that particular pathogen. The immune system responds to antigens by producing cells that directly attack the pathogen, or by producing special proteins called antibodies.
