Answer:

D. A population with high genetic biodiversity is better able to respond to environmental stressors.

Explanation:

The genetic biodiversity of a species is the diversity of alleles that it possesses in its genetic pool. For a given gene, a population can have one or more alleles; and the more alleles the population has, it will be more diverse. Under normal conditions (without stress), the alleles that are present in high frequency in a population,  are those that best respond to the environment where the population occurs. However, if some environmental condition changes and some type of environmental stress emerge (ie drought), it is possible that these alleles no longer respond equally effectively and then, it is possible that the  alleles that on normal conditions occur with low frequency, are more adequate to face the stress. A population with fewer alleles (less genetic diversity) has terefore fewer options to deal with environmental stressors and<u> a population with high genetic biodiversity</u> will do this better.

The hormones secretin and cholecystokinin target the pancreas, ________, and ________ to release pancreatic juice and bile into
elixir [45]

Answer: The hormones secretin and cholecystokinin target the pancreas, stomach, and gallbladder.

Explanation:

The duodenum secretes two additional hormones. Cholecystokinin (CCK), like enterogastrone, is secreted in response to the presence of fat in the chyme. CCK stimulates the contractions of the gallbladder, injecting bile into the duodenum so that fat can be emulsified and more efficiently digested. The other duodenal hormone is secretin. Released in response to the acidity of the chyme that arrives in the duodenum, secretin stimulates the pancreas to release bicarbonate, which then neutralizes some of the acidity.

Prescription medication is the least likely to affect the results and interpretation of a functional MRI.

Here are some of the factors that is most likely to affect the results of MRI :

- Caffeinated soda. Caffeinated soda tend to constrict the blood vessels in the brain, which will affect MRI results.
- cancerous growth, will create a huge shadow on MRI results
- sprained ankle, especially if it was fixed with metal bandage, will cause harm during MRI

A personal trainer thinks her clients get better workouts and are stronger if they listen to music while working out. Over the n
katrin [286]

Answer:

The correct answer is: the group of 10 people that lifted the barbell with music is the control group.

Explanation:

The personal trainer made an experiment to test her hypothesis. When experiments are being made, is common to have a control group and an experimental group.

The control group is the one that is subjected to the usual conditions, the group that shows what normally happens. The experimental group is the opposite, this group is observed while it goes through an unusual condition that may impact how they perform in the task observed.

<u>The personal trainer thinks that playing music for her clients is of benefit to them, so we can assume that she always plays music during the workouts, which means that the control group is the one that is listening to music while lifting a barbell</u>. The group that worked out without music is the experimental group because they were the ones that performed that activity with a change in their normal environment.
