The correct answer is: Endoplasmic reticulum.
One of the functions of the endoplasmic reticulum is transport of secretory proteins. Synthesized proteins are transported in vesicles to the Golgi apparatus.
Gastric chief cells have a high rate of enzyme secretion such as pepsinogen and gastric lipase. It is the cell also responsible for secretion of chymosin.
I think that the answer is b) radiation
Chemotherapy is a term which we usually related to the treatment of cancer. In cancer the malignant cell keeps on dividing themselves and also infect the near by cell to enter into a phase of no restrictive division. In chemotherapy, a drug or medicine either individually or in combination with other medicines is either directly introduced in the blood or is injected only on the targeted cell. The chemotherapy interacts with the cell division process of the cell directly or indirectly. In the direct process the cell division process either mitosis or meiosis is impaired or the essential hormones or enzymes required for cell divisions are attacked through cytotoxic drug. It also inhibits cell division through apoptosis strategy where the cancerous cell starts dividing themselves. The chemotherapy process is to be done regularly over a certain period of time. Usually the treatment course occurs from a day to few weeks’ time. The dosage of chemical is given either orally or injected into the body fluid or either through intravenously.
Apart from benefits there can be several side effects of chemotherapy:
a) A patient may get pucky feelings and in some cases may have nausea or vomiting
b) There are also chances of hair loss.
c) It can also adversely affect the skin, as it may get dry or oversensitive.
d) The blood platelet count may decrease
e) There can be chances of hearing and vision impairment.
Answer:
C) The main predator of these fish is another species of fish on which alligators also prey
Explanation:
The only reasonable explanation as to why the species of fish experiences decline in number despite the fishing being the same, and the number of alligators that preyed on the fish going down, is another species of fish which preyed upon the fishes that are fished, but the alligators were also preying on them. Since the alligators have been mostly removed from the ecosystem, the fish that preyed on the other fishes experienced significant increase in its numbers, and since it feeds upon the other fish, that resulted in constant decline in the population of those fishes. The decline in number will only stop when the carrying capacity is reached for the predatory fish in the ecosystem.
Answer:
Your answer should be D. A section of DNA that codes for a specific trait.
