Answer:
b. the activity of lipoprotein lipase.
Explanation:
Lipoprotein lipase (LPL) is considered or known to be a rate-limiting enzyme that hydrolyzes circulating triglyceride-rich lipoprotein such as very low density lipoproteins and chylomicrons.
It is known that the Lipoprotein lipase is activated by glucagon and adrenaline. And this why the activity of LPL increases in muscle tissue and decreases in adipose tissue, during fasting while , its activity decreases in muscles tissue and increases in adipose tissue.
It is known that, it plays an important role in breaking down fat in the form of triglycerides, which are carried from various organs to the blood by molecules called lipoproteins.
In conclusion, women fat cells in the breasts, hips, and thighs produce abundant LPL, storing fat in those body sites , while in men, fat cells in the abdomen produce abundant LPL.

In biology, mutualism is how two different organisms survive upon the activity
of the other. Each benefits from the mutual relationship. In the case of bees
pollinating flowers, both the bees and the flowers need something and benefit
from the interaction with the other. </span>
The correct answer is: introns
Processing of mRNA is process that occurs only in eukaryotic cells. After the transcription, newly formed mRNA molecule is called and it must be processed into a messenger RNA (mRNA). Processing includes:
• Addition of a 5' cap to the beginning of the RNA
• Polyadenilation- addition of a poly-A tail (tail of A nucleotides) to the end of the RNA
• Splicing- removal of introns and linking the exons
After these steps mRNA is mature and used for the further steps (e.g. translation).
Sometimes some genes are alternatively spliced.
