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:
d) The frequencies of the alleles for dark wing color in the moth population
changed.
Answer:
DNA: ACT TTC GAT
mRNA: UGA AAG CUA
tRNA: ACU UUC GAU
AA: stop-lysine-leucine
Explanation:
mRNA is the complementary sequence of the DNA strand and tRNA is a complementary sequence of mRNA sequence. mRNA is a sequence of bases that is formed by encoding the DNA sequence in the complementary pattern during transcription.
tRNA is complementary of the mRNA code to produce the amino acid which is decided by the codon ( a three- base sequence of mRNA) what amino acid be present in what sequence.
Thus,
DNA: ACT TTC GAT
mRNA: UGA AAG CUA
tRNA: ACU UUC GAU
AA: stop-lysine-leucine (however, after the stop codon amino acid chain terminated in any protein)
Amino Group, Carboxyl Group, and the R group
Well oxygen has 6 electrons in its outer shell and mg has 2. Oxygen need two to complete it's outer shell and mg needs to lose 2 to gain a complete out we shell.
