1. What is the name of the condition characterized by swelling caused by a buildup of lymph fluid?

• A. Anemia
• B. Edema
• C. Hypertension
• D. Diabetes

Correct answer: B

Rationale: Edema is the condition characterized by swelling caused by a buildup of lymph fluid. It occurs when excess fluid is trapped in the body's tissues. Anemia (A) is a condition characterized by a lack of healthy red blood cells, leading to a reduced ability to carry oxygen in the blood. Hypertension (C) is high blood pressure, a condition where the force of the blood against the artery walls is too high. Diabetes (D) is a condition characterized by high blood sugar levels, either due to insufficient insulin production or the body's resistance to insulin, leading to various complications.

2. Which vitamin requires the lymphatic system for proper absorption from the intestine?

• A. Vitamin A
• B. Vitamin C
• C. Vitamin D
• D. Vitamin B12

Correct answer: C

Rationale: The correct answer is Vitamin D. Vitamin D requires the lymphatic system for proper absorption from the intestine. Unlike vitamins A, C, and B12, which are absorbed directly into the bloodstream, vitamin D is absorbed into the lymphatic system first before entering the bloodstream. Therefore, options A, B, and D are incorrect as they do not rely on the lymphatic system for absorption from the intestine.

3. What is the periodic table?

• A. A table of elements that are arranged in order of increasing atomic number.
• B. A table of elements that are arranged in order of increasing atomic mass.
• C. A table of elements that are arranged in order of their reactivity.
• D. A table of elements that are arranged in order of their color.

Correct answer: A

Rationale: The periodic table is a tabular arrangement of the chemical elements, organized based on their atomic number, electron configurations, and recurring chemical properties. Elements are placed in rows (periods) and columns (groups) with similar properties. The elements are listed in order of increasing atomic number, which is the number of protons in the nucleus of an atom. This arrangement reveals a periodic repetition of chemical properties, forming the basis of the periodic law. Choice B, which suggests arranging elements based on increasing atomic mass, is incorrect because the periodic table is primarily organized by atomic number, not atomic mass. Choices C and D are also incorrect as the periodic table is not based on reactivity or color of elements, but rather on atomic number and properties.

4. If 5y - 7 = 13, what is y?

• A. 4
• B. 5
• C. 6
• D. 7

Correct answer: A

Rationale: To solve the equation 5y - 7 = 13, start by adding 7 to both sides to isolate the term with y: 5y = 20. Then, divide by 5 to solve for y, which gives y = 4. Therefore, the correct answer is A. Choice B, C, and D are incorrect as they do not yield the correct solution when substituted into the equation. It's important to follow the proper steps in solving linear equations to arrive at the correct answer.

5. Which hormone, produced by the adrenal glands, helps regulate the body's response to stress, including increasing blood pressure and suppressing the immune system?

• A. Aldosterone
• B. Epinephrine
• C. Cortisol
• D. Insulin

Correct answer: C

Rationale: Cortisol is the correct answer. It is the hormone produced by the adrenal glands that helps regulate the body's response to stress. Cortisol plays a crucial role in increasing blood pressure and suppressing the immune system during stressful situations. Aldosterone, another hormone from the adrenal glands, primarily regulates salt and water balance in the body, not the stress response. Epinephrine, also known as adrenaline, is produced by the adrenal glands in response to stress, but its effects are more immediate and short-lived compared to cortisol. Insulin, produced by the pancreas, regulates blood sugar levels and is not directly involved in the body's response to stress.
