Kidney disease can cause hypertension by:
Directly signaling the brain stem to increase blood pressure.
Activating the renin-angiotensin mechanism.
Increasing release (excretion) of sodium and water.
Stimulating the secretion of ANP.
The Correct Answer is B
Kidney disease can cause hypertension by activating the renin-angiotensin mechanism.
This mechanism involves the release of renin from the kidneys, which stimulates the production of angiotensin II, a hormone that constricts blood vessels and increases blood pressure.
Choice A is wrong because kidney disease does not directly signal the brain stem to increase blood pressure.
The brain stem regulates blood pressure through the autonomic nervous system, which responds to various stimuli such as stress, pain, or emotions.
Choice C is wrong because kidney disease does not increase the release (excretion) of sodium and water.
On the contrary, kidney disease can impair the ability of the kidneys to filter out excess sodium and water, which can lead to fluid retention and increased blood pressure.
Choice D is wrong because kidney disease does not stimulate the secretion of ANP.
ANP stands for atrial natriuretic peptide, a hormone that is secreted by the heart when it senses high blood pressure.
ANP causes the kidneys to excrete more sodium and water, which lowers blood pressure.

Correct Answer is B
Explanation
Monocytes are a type of agranulocytes, which are white blood cells that lack visible granules in their cytoplasm.
Agranulocytes also include lymphocytes, which are involved in adaptive immunity.
Choice A is wrong because basophils are a type of granulocytes, which are white blood cells that have granules in their cytoplasm.
Granulocytes also include neutrophils and eosinophils, which are involved in innate immunity.
Choice C is wrong because neutrophils are also a type of granulocyte.
Neutrophils are the most abundant white blood cells and are responsible for phagocytizing bacteria and fungi.
Choice D is wrong because eosinophils are also a type of granulocytes. Eosinophils are involved in allergic reactions and parasitic infections.
Normal ranges for white blood cells vary depending on age, gender, and health status, but generally, they are between 4,000 and 11,000 cells per microliter of blood.
Correct Answer is A
Explanation
The antibodies produced in allergic reactions belong to the immunoglobulin E group.
These antibodies bind to an allergen, triggering a release of histamine, which causes allergy symptoms.
They also help to fight parasitic infections.
Choice B is wrong because allergens are not antibodies, but substances that cause an allergic reaction.
Choice C is wrong because the antibodies that belong to the immunoglobulin G group are not involved in allergic reactions, but in fighting bacterial and viral infections.
Choice D is wrong because mast cells are not antibodies, but cells that release histamine and other chemicals when activated by IgE antibodies.
