1. Homeostasis is the maintenance of a constant internal environment.
2-5: The diagram below shows many of the endocrine glands in a human.
3. Label M is ...
4. A person was sweating, had an increased pulse rate, was breathing quickly and had large wide pupils. Which gland would have secreted the hormone that caused this response?
5. The hormones secreted by the endocrine glands travel to their target organs ...
6-9: A healthy student drank a sports drink containing glucose. The graph shows the changes in the levels of glucose in her blood during the hour after the drink.
7. What is the name of the hormone X?
Question 1:
The correct word to complete the sentence is hormones.
*These A.I. responses have been individually checked to ensure they match the accepted answer, but explanations may still be incorrect. Responses may give guidance but the A.I. might not be able to answer the question! This is particularly the case for questions based on diagrams, which the A.I. typically cannot interpret. Grade Gorilla uses Gemini, Deepseek and a range of other A.I. chatbots to generate the saved responses. Some answers have had human intervention for clarity or where the A.I. has not been able to answer the question.
Question 2:
A. the pituitary gland
Reasoning: Located at the base of the brain, the pituitary gland is often called the "master gland."
Question 3:
Label M is... B. the pancreas
Reasoning: Situated behind the stomach, the pancreas is responsible for secreting insulin and glucagon.
Question 4:
C. gland N
Reasoning: The symptoms described (sweating, increased pulse, rapid breathing, dilated pupils) are part of the "fight or flight" response caused by adrenaline. This hormone is secreted by the adrenal glands, which are labeled as N in the diagram.
Question 5:
The correct answer is:
B. in the plasma of the blood
Explanation:
Hormones are secreted by endocrine glands directly into the bloodstream.
They travel dissolved or carried in blood plasma (the liquid component of blood) to reach their target organs.
They do not travel as nervous impulses (A), inside red blood cells (C), or primarily via the lymphatic system (D), though some hormones may enter lymph fluid indirectly before reaching blood.
So, B is correct.
Question 6:
Answer: B. 20 mins
Reasoning: Looking at the line labeled "Glucose levels" (the blue line), the highest point (peak) occurs at the 20-minute mark on the x-axis.
Question 7:
Answer: D. Insulin
Reasoning: Hormone X rises in response to the increase in blood glucose. Insulin is the hormone responsible for lowering blood sugar levels when they become too high.
Question 8:
Answer: C. Pancreas
Reasoning: The pancreas contains specialized cells (beta cells) that detect high glucose levels and secrete insulin into the bloodstream.
Question 9:
Answer: C. The glucose level would rise and stay high
Reasoning: In diabetes, the body either does not produce enough insulin or cannot use it effectively. Therefore, after consuming glucose, the blood sugar levels would increase significantly and remain elevated because the mechanism to bring them back down is impaired.
Question 10:
A. glucose to move from the blood into cells.
Insulin helps lower blood glucose levels by promoting the uptake of glucose into cells (especially muscle and fat cells) for energy or storage.
It also stimulates the liver to store glucose as glycogen (not protein — so B is wrong).
C and D describe effects opposite to insulin (those are related to glucagon, not insulin).
So, A is correct.
