Which of the following scenario demonstrates apoptosis?
sp2606 [1]

Given what we know, we can confirm that the scenario that best demonstrates the mechanism of apoptosis is 1, "An immune cell Self-destructs once it is no longer needed by the immune system".

<h3>What is apoptosis?</h3>
  • This is what we describe as a programmed cellular death.
  • This means that when a cell is no longer needed or is damaged or old, it is programmed to automatically self-destruct in order to make room for new cells.
  • This is also an effective way to reuse the resources the cell contained.
  • When this mechanism fails, it can often lead to the formation of cancer.

Therefore, we can confirm that option 1 which states "An immune cell Self-destructs once it is no longer needed by the immune system" is the best description available of apoptosis given its definition as a programmed cellular death.

A farmer is being troubled by coyotes eating his sheep. in an attempt to solve the problem, he kills a sheep and laces its body
Misha Larkins [42]
The farmer is attempting to apply the principle of conditioned taste aversions to accomplish his objectives. Conditioned taste aversion occurs when an animal associates the taste of a certain food with symptoms caused by a toxic, spoiled, or poisonous substance. Generally, taste aversion is developed after ingestion of food that causes nausea, sickness, or vomiting.Tate aversions is an important principle that help us better understand animals and people tend to form one pairing associations between a certain stimuli, unlike other classical conditioning examples, for it one eats a food and becomes ill, he or she is predisposed to avoid the substance.
