Which of the following is true about diabetes?
A. The pancreas overproduced glucose, and so insulin must be injected to reduce glucose levels.
B. The pancreas underproduced glucose, and so insulin must be injected to increase glucose levels
C. The pancreas overproduced insulin, and so glucose must be injected to regulate insulin levels.
D. The pancreas underproduced insulin, and so insulin must be injected to regulate glucose levels.
I think its D or B
2. which of the following best describes the function of the endocrine system
A. it secretes chemical messengers that travel through the blood to signal changes at target cells.
B. It blinds chemical messengers that travel through the blood from target cells.
C. It releases electrical impulses that travel through body cells to signal changes at target cells.
D. It converts chemical messages into electrical impulses to signal changes at target cells.
I think this is A
Please check
For the first question, the correct answer is D. The pancreas underproduces insulin, so insulin must be injected to regulate glucose levels.
To arrive at this answer, let's analyze the options:
A. The pancreas overproduced glucose, and so insulin must be injected to reduce glucose levels. This option is incorrect because the pancreas does not produce glucose; it produces insulin.
B. The pancreas underproduced glucose, and so insulin must be injected to increase glucose levels. This option is incorrect because insulin lowers blood glucose levels, so injecting more insulin would further decrease glucose levels.
C. The pancreas overproduced insulin, and so glucose must be injected to regulate insulin levels. This option is incorrect because the pancreas does not produce glucose; it produces insulin.
D. The pancreas underproduced insulin, and so insulin must be injected to regulate glucose levels. This option is correct because in type 1 diabetes (the most common form of diabetes where the pancreas produces little to no insulin), insulin injections are required to regulate glucose levels.
For the second question, you are correct. The correct answer is A. The function of the endocrine system is to secrete chemical messengers (hormones) that travel through the blood to signal changes at target cells.
To arrive at this answer, let's analyze the options:
A. It secretes chemical messengers that travel through the blood to signal changes at target cells. This option is correct because hormones are secreted by endocrine glands, travel through the bloodstream, and act on specific target cells to regulate various bodily functions.
B. It blinds chemical messengers that travel through the blood from target cells. This option is incorrect because the endocrine system does not blind chemical messengers; it releases them.
C. It releases electrical impulses that travel through body cells to signal changes at target cells. This option is incorrect because the endocrine system primarily relies on chemical messengers (hormones) rather than electrical impulses.
D. It converts chemical messages into electrical impulses to signal changes at target cells. This option is incorrect because the endocrine system does not convert chemical messages into electrical impulses. It primarily relies on chemical messengers (hormones).
For the first question, the correct answer is D. In diabetes, the pancreas underproduces insulin, so insulin must be injected to regulate glucose levels.
For the second question, the correct answer is A. The endocrine system secretes chemical messengers (hormones) that travel through the blood to signal changes at target cells. These hormones play a vital role in regulating various bodily functions.
So, your answers are correct. Well done!
