Answer:
B. Bile would be released from the gallbladder to emulsify the fat in the duodenum
Explanation:
Bile juice is secreted by the liver but is stored in the gallbladder. It is released from the gallbladder into the duodenum of the small intestine when the fat-rich food is ingested.
Bile juice serves to breakdown the large globules of fats into smaller droplets to facilitate its chemical digestion by lipase enzyme. This process is called emulsification. Hence, the intake of fat-rich food makes gallbladder to release bile juice in the small intestine to carry out the emulsification of fats.
Answer/Explanation:
Telomeres are structures found at the end of the chromosomes. They are protective structures made of repetitive sequences. They protect chromosomes from damage or fusing with other chromosomes. As the cell divides and divides, telomeres shorten. When they reach a critical point, the cell stops dividing, and might even undergo apoptosis (die).
Telomerase is an enzyme that adds nucleotides to telomeres to prevent their shortening. If all our cells expressed telomerase, the telomeres would never reach the critical short length to stop cell division. Therefore, our cells would keep dividing forever!
