Natural selection, one of the mechanisms of evolution, can result in progress and </span>cause some organisms to develop characteristics they need. But generally speaking, natural selection is not the only mechanism of evolution. Other evolutionary mechanisms, such as genetic drift, mutations, migration, can in some cases have a harmful outcome.
Answer;
C. Be more susceptible to disease and famine
Explanation;
-A species that has experienced a severe bottleneck event would be expected to be more susceptible to disease and famine.
-The Bottleneck Effect occurs when there is a disaster of some sort that reduces a population to a small handful, which rarely represents the actual genetic makeup of the initial population.
-It may be caused by various events, such as an environmental disaster, the hunting of a species to the point of extinction, or habitat destruction that results in the deaths of organisms.

Endorphins are a type of neuropeptides short strings of amino acids that are narrowly targeted to perform a specific job. For instance, endorphins specialize in reducing pain.
<u>Explanation:</u>
Endorphins are opiod neuropeptides that are produced by the central nervous system. They are natural pain killers that are produced by our body to reduce pain.
They are of 3 types namely, alpha endorphins, beta endorphins and gamma endorphins. All of these specifically bind to the opioid receptors inhibiting the communication of pain signals.
Answer:
The number of white blood cells in the blood can increase during an immune response. These cells travel through the circulatory system and the lymphatic system to an injured or infected area of the body. White blood cells leave the blood vessels and travel into the damaged tissue, where the immune response takes place.
