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.

Phenotype - short , Tall
Genotype - tt (short) , TT or Tt (tall)
<u>Explanation:</u>
In Mendelian Genetics, <em>Dominant traits</em> are represented by capital letters and <em>Recessive traits</em> are represented by small letters.
So if height is the character considered, then the traits would be short and tall.
Tall is the dominant phenotype and short is the recessive phenotype.
The alleles of the gene for height are T and t.
The genotype for Tall trait is TT or Tt.
The genotype for short trait is tt.
Therefore, the symbol representation of phenotype (Tall) is TT or Tt and for phenotype (short) is tt.
MRNA is read 5->3
Start codons can vary depending on the cell/organism type although more generally for mRNA it is always: AUG which is always Methionine
Stop codons for mRNA are:
<span>UAG ("amber") , UAA ("ochre"), <span>UGA ("opal")

<span>5'-uaucc.aug.gca.cuu.uaa.ac-3'

Answer:
The main role of DNA in the cell is it's a Long term storage of information
Explanation:
The main role is to read the genetic code, cells make a copy of a stretch of DNA in the nucleic acid RNA
The medial pre Frontal Cortex neurons synapting with the intercalated cells of Amygdala contains <u>GABA</u> as the neurotransmitter.
Option a
<u>Explanation:</u>
The Amygdala has two types of nerve cells getting attached with it primarily. They are the fibres from the mPFC or medial pre Frontal Cortex and the vIPAG or ventrolateral periaqueductal grey. These neurons do have different functions on the whole body.
The fibres from the mPFC do have emotional function on the human body whereas the fibres of vIPAG do have an effect on the muscle tone
. And it's seen that both the nerve fibres that are getting attached with the intercalated cells of Amygdala do secrete GABA and are inhibitory GAB Anergic in nature.
