1. the amount of glucose in the bloodstream is regulated by the feedback shown in the diagram.

each event listed in the table below will have some effect on a persons body. based on the description of the event, write its effect on the body. the choices are: raise blood glucose, lower blood glucose, or would have no effect on blood glucose levels based on the diagram.

event	raise, lower, no effect
some body cells lose the ability to take up glucose.
tissue in the pancreas is unable to make glucagon.
as a result of a car crash, a person loses 10% of their liver
ms. piro skips breakfast and lunch and doesnt eat until dinner time.

Explanation:

Step1: Analyze eating a Snicker's bar

A Snicker's bar is high - in sugar. When eaten, it will increase the amount of glucose entering the bloodstream, so it will raise blood glucose.

Step2: Analyze body cells losing glucose - uptake ability

If body cells can't take up glucose, glucose will remain in the bloodstream, causing blood glucose levels to rise.

Step3: Analyze inability to make glucagon

Glucagon raises blood glucose by breaking down glycogen in the liver. If it can't be made, the body has one less mechanism to raise blood glucose, but in the short - term, it may not immediately cause a change. However, over time, when blood glucose drops, it won't be raised as effectively, but initially, it has no effect on blood glucose levels.

Step4: Analyze losing 10% of the liver

The liver is involved in storing and releasing glucose. Losing part of it may affect its function, but 10% loss may not immediately change blood glucose levels, so it has no effect.

Step5: Analyze skipping meals

Skipping breakfast and lunch means less glucose is being ingested. This will cause blood glucose levels to lower.

Answer:

Event	Raise, Lower, No Effect
Some body cells lose the ability to take up glucose.	Raise blood glucose
Tissue in the pancreas is unable to make glucagon.	No effect
As a result of a car crash, a person loses 10% of their liver	No effect
Ms. Piro skips breakfast and lunch and doesn't eat until dinner time.	Lower blood glucose
