Identify the endocrine glands labeled 1-4 and their functions in regulating bodily processes, and compare hormones and nerves.

here are the solutions for Question 4 from the image.

Question 4

4.1
The diagram provided labels parts 1, 2, 3, and 4. Parts A and D are not explicitly labeled in this diagram.

4.2
First, let's identify the numbered parts in the diagram:

• 1: Pituitary gland
• 2: Thyroid gland
• 3: Pancreas
• 4: Adrenal gland

Now, let's answer the sub-questions:

• a) Produces the hormone glucagon: 3, Pancreas
• b) Produces a hormone that controls the growth of long bones: 1, Pituitary gland
• c) Produces an iodine-containing hormone: 2, Thyroid gland
• d) Produces a hormone that is involved in the re-absorption of some salts by the kidneys: 4, Adrenal gland

4.3
Two similarities between hormones and nerves with regard to their functions are:

• Both systems transmit chemical signals to target cells or organs.
• Both systems are involved in regulating body functions and maintaining homeostasis.
