Answer:
Hypertonic blood draws water out of the interstitial fluid, which makes the interstitial fluid hypertonic. This, in turn, draws water out of the cells.
Basically an hype tonic blood has high solute potential,( low water potential) compare with the surrounding plasma and the interstitial fluid. Thus the interstitial fluid is hypotonic to the blood.
Consequently,water with higher potential moves from the interstitial fluid medium into the blood by osmosis through the capillary endothelial. This raises the water potential of the blood, lowering the solute potential, thus making it hypotonic to the interstitial fluid; which is now hypertonic(lower water potential ,due to loss to the blood by osmosis).
Since the interstitial fluids is now hyper tonic to the surrounding cells, water moves from the hypo tonic surrounding cells through osmosis into the interstitial fluids. The sequence continues until a stable internal environment is achieved,
Answer:
Option A
Explanation:
In this case, there are two varieties of horses: Domestic horses that are raised and bred by humans and Wild horses that lives in the wild. The issue of varieties in coat colour of domestic horses can be explained as what occured by selective breeding, also known as artificial selection which is a technique by which humans develop new offsprings with desirable and suitable characteristics. These breeders select two parents that possess beneficial phenotypic traits to mate, producing offsprings with those desired traits such as strength and also for coat colour as stated.
<span>Answer:
Parabiosis is an effective way to evaluate hormone function because it permits the exchange of only long-lived molecules (such as hormones) between the two joined individuals. Thus, the glucose levels of each mouse will stay the same, but the hormone levels will not. The db mutant's hormone level will decrease, and the wild type's hormone level will increase.
Coleman's goal was to determine if the ob and db genes function in the hormonal regulation of appetite and body fat. In this experiment, if both appetite-suppressing hormone and glucose were exchanged, it would be impossible to determine whether any weight changes in the mice were caused by the transfer of hormone or the transfer of glucose from one mouse to the other. For example, an increase in hormone level (and thus greater appetite suppression) could lead to weight loss, as could a decrease in glucose level. On the other hand, a decrease in hormone level or an increase in glucose level could lead to weight gain.</span>
