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 best answer from the list of options is option D (They are colorless and feed on other, smaller cells)
Explanation:
Euglenas have cells that contain chloroplasts, which means they can make their food like plants through photosynthesis, and when it is dark where they can't get sunlight they can also make food by engulfing their prey through the plasma membrane and absorb them. Euglenas are heterotrophic since they call also feed on smaller cells. Their whip-like tail when viewed under the microscope, is colorless. However, the chloroplasts make them appear green and they can also come in red color.
The daughter cells are produced with only half the chromosomes of the parent cell. The correct option among all the options given in the question is option "D". So the main goal of meiosis is actually creating four daughter cells that are by no means similar to the parent cells.
When these daughter cells that
are created combine together and undergo the process of fertilization, then a
zygote is formed and the development of cells starts. The process of meiosis
can be asexual as well as sexual.
