Mice are common subjects for medical experiments because the responses of their body systems are very similar to human responses. A scientist is planning an experiment to investigate homeostasis in mice. The steps of the procedure are listed below. The procedure involves mice that have not eaten for 24 hours. 1. Divide the mice into two groups, labeled A and B. 2. Take a blood sample from each mouse. Measure the levels of blood glucose and insulin. 3. Feed the mice in Group A a high-sugar food, such as candy bars. Do not feed the mice in Group B. 4. Repeat Step 2 of the procedure. 5. Repeat Step 2 again, every 5 minutes for 1 hour. Identify the choice that best completes the statement or answers the question. Which group of mice can be expected to show the higher blood insulin levels in Step 4?

Clarissa Bray · Answer 1

Group A rats may have higher blood insulin levels in step 4.

Explanation:

Group B rats are on an intermittent fasting diet, which means that the blood sugar level of these rats is low and, consequently, insulin levels will also be low, since insulin is the hormone that allows the entry of sugar in the cells. In addition, intermittent fasting can damage insulin excretory cells, further decreasing the level of this hormone in the blood.

However, the group A rats were fed with chocolate bars, which increased the levels of sugar in their blood, causing the body to release more innsulin so that this sugar could be absorbed by the cells.

In this case, we can say that group A mice have more insulin in their blood than group B mice during phase 4 of the experiment.

Alma Vega · Answer 2

The group of mice that can be expected to show the higher blood insulin levels in Step 4 are:

Group A mices.

Explanation:

The reason behind this answer is simple, assuming mice bodies are similar to human bodies. They also use insulin to break glucose, fructose, and all sugars in the body to be processed by the cells and used as a source of energy or store it. Following this assumption and association, we can conclude that mice without food are not going to have high insulin levels, while mice with big amounts of sugar in any type in their body will produce more insulin to process the sugars.
