Target cells for releasing hormones are in the:
Anterior pituitary gland.
Hypothalamus.
Thyroid gland.
Posterior pituitary gland.
The Correct Answer is B
The hypothalamus is the part of the brain that produces hormones that control the pituitary gland.
The pituitary gland then releases hormones that target other endocrine glands, such as the thyroid, adrenal, and gonads.
Therefore, the hypothalamus is the source of releasing hormones for target cells in the anterior pituitary gland.
Choice A is wrong because the anterior pituitary gland does not produce releasing hormones, but responds to them by secreting other hormones.
Choice C is wrong because the thyroid gland does not produce releasing hormones, but responds to them by secreting thyroid hormones.
Choice D is wrong because the posterior pituitary gland does not produce releasing hormones, but stores and releases hormones made by the hypothalamus, such as oxytocin and antidiuretic hormone.

Correct Answer is A
Explanation
A person with type AB blood can successfully receive blood from all blood types.
This is because type AB blood has both A and B antigens on the surface of red blood cells, and therefore does not have antibodies against either antigen in the plasma.
Type AB blood is also called the universal recipient.
Choice B is wrong because type AB blood can receive more than just type O blood.
Type O blood is the universal donor, meaning it can be given to anyone, regardless of their blood type.
Choice C is wrong because type AB blood can receive more than just two of the blood types. Type AB blood can receive both A and B blood, as well as O and AB blood.
Choice D is wrong because type AB blood can receive more than just one of the blood types. Type AB blood can receive any blood type without problems.
Normal ranges for blood types vary by population, but generally, type O is the most common, followed by type A, type B, and type AB.
Correct Answer is B
Explanation
Epinephrine, also known as adrenaline, is a hormone that the adrenal medulla secretes in response to stress or low blood sugar levels.
It helps the body react to stress by increasing blood pressure, heart rate, oxygen delivery to muscles, and blood sugar levels.
Choice A is wrong because mineralocorticoids are hormones that the adrenal cortex secretes, not the adrenal medulla.
They help regulate the balance of sodium and potassium in the body.
Choice C is wrong because glucocorticoids are also hormones that the adrenal cortex secretes, not the adrenal medulla.
They help control the body’s use of fats, proteins, and carbohydrates, suppress inflammation, and regulate blood pressure and blood sugar.
Choice D is wrong because aldosterone is a specific type of mineralocorticoid that the adrenal cortex secretes, not the adrenal medulla.
It helps regulate the balance of sodium and water in the body.
