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).
Answer:
Due to their being no options (possibly just an incomplete question), I will just give an answer. So for panda bears, if their food sources became unavailable, they would most likely be in danger of becoming extinct.
But one thing is, pandas do have the ability to survive with bamboo.
But since bamboo comprises 99 percent of their food, although they also consume other plants and even meat, I highly doubt they could (whose make the remaining 1 percent ).
Because the gene T1R1 mutated some 4 million years ago, causing them to lose the ability to taste umami, giant pandas have come to rely significantly on bamboo (which is what makes meat tasty for omnivores and carnivores). The availability of bamboo trunks at the time coincided with their purported food source becoming increasingly limited, thus pandas became used to them and began to rely significantly on them, as they do now.

We basicly can't digest them as it has cellulose and we can't digest cellulose .acc. to me in olden days early men used to survive with raw green plants because the cellulose is digested by our appendix but slowly as we stopped eating raw green plants the appendix lost it function tooo. so we should always eat a selective plant like lettuce
<span> parathyroid hormone (PTH) </span><span>increases osteoclast activity to release more calcium ions into the bloodstream.
In short, Your Answer would be Option C
Hope this helps!</span>
