Answer:
(B). inhibiting HMG-CoA reductase.
Explanation:
Lovastatin is a drug, which is used to reduce risk for cardiovascular diseases and to reduce level of cholesterol in blood.
It works by inhibiting HMG-CoA reductase (3-hydroxy-3-methylglutaryl-coenzyme A reductase) enzyme, required for the formation of mevalonate from HMG-CoA.
Mevalonate is building block for the biosynthesis of cholesterol. Hence, lovastatin inhibits cholesterol production by inhibiting synthesis of mevalonate.
Thus, the correct answer is option (B).
Answer:
Diarrhea - the most common cause of dehydration and related deaths. The large intestine absorbs water from food matter, and diarrhea prevents this from happening. The body excretes too much water, leading to dehydration.
Vomiting - leads to a loss of fluids and makes it difficult to replace water by drinking it.
Sweating - the body's cooling mechanism releases a significant amount of water. Hot and humid weather and vigorous physical activity can further increase fluid loss from sweating. Similarly, a fever can cause an increase in sweating and may dehydrate the patient, especially if there is also diarrhea and vomiting.
Diabetes - high blood sugar levels cause increased urination and fluid loss. Tips for handling summer heat for people with diabetes.
Frequent urination - usually caused by uncontrolled diabetes, but also can be due to alcohol and medications such as diuretics, antihistamines, blood pressure medications, and anti psychotics.
Burns - blood vessels can become damaged, causing fluid to leak into the surrounding tissues.

Answer:
False.
Explanation:
Intravenous drug administration consists of applying a drug directly into the patient's vein. This type of drug administration promotes more accurate observations on the drug's effects on the patient's body and on the drug's effectiveness in fighting the disease, mainly because intravenous administration allows the drug to act faster, even when applied in large volumes.
Answer: 1. Blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium of the heart. As the atrium contracts, blood flows from your right atrium into your right ventricle through the open tricuspid valve.
2. Plasma is the main component of blood and consists mostly of water, with proteins, ions, nutrients, and wastes mixed in. Red blood cells are responsible for carrying oxygen and carbon dioxide. Platelets are responsible for blood clotting. White blood cells are part of the immune system and function in immune response.
3.Within the bone marrow, all blood cells originate from a single type of unspecialized cell called a stem cell. When a stem cell divides, it first becomes an immature red blood cell, white blood cell, or platelet-producing cell.
4. Epinephrine and norepinephrine, hormones secreted by the adrenal medulla, raise blood pressure by increasing heart rate and the contractility of the heart muscles and by causing vasoconstriction of arteries and veins. These hormones are secreted as part of the fight‐or‐flight response.
