Answer:
Peristalsis is the term for the involuntary muscular contractions that propel solid and semisolid materials through the alimentary canal.
Explanation:
Peristalsis is a wave-like muscle contraction due to the involuntary movements of the longitudinal and circular muscles in the alimentary canal (digestive tract). It also occurs in other hollow tubes of the body such as the urinary tract. In the digestive tract, it begins at the upper portion of the esophagus and also occurs in the stomach and intestines.
When food is swallowed, the peristaltic waves push the food down the esophagus into the stomach. The muscles in the stomach continue the peristalsis and the food moves through the digestive tract, where it is further digested and broken down with the help of digestive juices present in the stomach and small intestine. The peristalsis is continued by the muscles of small intestines, where the nutrients in the digested food are absorbed into the bloodstream. The movement of bile from the gallbladder into the duodenum of the small intestine also occurs via peristalsis. The undigested food is then passed to the large intestine, where the peristalsis continues and it is eliminated through the anus as feces after the reabsorption of water and some minerals.
When peristalsis does not occur, it may cause disorders such as dysphagia (difficulty in swallowing foods and liquids), irritable bowel syndrome (diarrhea or constipation), esophageal spasms, gastroparesis (muscles of the stomach not moving food into the small intestine) and GERD (Gastroesophageal reflux disease).
I’m confuse between A and B but I think it is mostly B
Answer:
A) special proteins would open the promoter while
Explanation:
A promoter is an area of DNA that can be bound to be proteins in order to initiate processes such as transcription. These sequences are usually a repetitive code.

Answer:
Synthesize new drugs expand the world’s food production.
Explanation:
Green revolution was started in the 1960's with the main aim to increase the food production by 60-70% to feed the increasing population. The food grains especially rice and wheat.
The green revolution can be more beneficial by applying the benefits of the genetics. The discovery of the new drug or improvement in the earlier food products or the introduction of the desired drug protein in the food can improve the health of the organisms.
Thus, the correct answer is option (C).
