1. Which of the following best describes the term monochromatic?

• A. having one color
• B. having many parts
• C. having a lot of time
• D. having too much heat

Correct answer: A

Rationale: The term 'monochromatic' refers to something that has only one color. Choice A, 'having one color,' is the correct description for monochromatic. Choices B, C, and D are incorrect as 'monochromatic' does not mean 'having many parts,' 'having a lot of time,' or 'having too much heat.' Monochromatic specifically conveys the idea of consisting of or using only one color, making Choice A the correct answer.

2. Convert 5 kilograms to grams.

• A. 50 grams
• B. 500 grams
• C. 5,000 grams
• D. 50,000 grams

Correct answer: C

Rationale: To convert kilograms to grams, you need to multiply by 1000 since there are 1000 grams in a kilogram. Therefore, 5 kilograms is equal to 5,000 grams. Choices A, B, and D are incorrect because they do not correctly convert the given amount of kilograms to grams.

3. What is the structural and functional unit of the kidney responsible for filtering blood?

• A. Nephron
• B. Ureter
• C. Urethra
• D. Bladder

Correct answer: A

Rationale: The nephron is the correct answer. It is the structural and functional unit of the kidney responsible for filtering blood. The nephron consists of a renal corpuscle (glomerulus and Bowman's capsule) and a renal tubule. Within the nephron, blood is filtered to form urine, which is then carried to the ureter for excretion from the body. Choices B, C, and D are incorrect because the ureter, urethra, and bladder are not involved in the filtration of blood in the kidney. Instead, they are parts of the urinary system responsible for transporting and storing urine.

4. What is the main target organ for insulin, the hormone produced by the pancreas?

• A. Liver
• B. Kidneys
• C. Muscles
• D. Brain

Correct answer: C

Rationale: The main target organ for insulin is muscles. Insulin plays a crucial role in regulating glucose metabolism by promoting the uptake of glucose into muscle cells. This glucose can then be utilized for energy production or stored for later use. Therefore, muscles are the primary site where insulin exerts its effects on glucose uptake and utilization. The liver primarily responds to insulin by regulating glucose storage and release, but the main target for insulin-mediated glucose uptake is muscles. Kidneys are not a target organ for insulin action in glucose metabolism. The brain does not heavily rely on insulin for glucose uptake as it primarily uses glucose independently of insulin for energy production.

5. What is the mode of the data set: 2, 3, 3, 4, 4, 4, 5?

• A. 2
• B. 3
• C. 4
• D. 5

Correct answer: C

Rationale: The mode of a data set is the value that appears most frequently. In this data set (2, 3, 3, 4, 4, 4, 5), the number 4 appears three times, which is more frequent than any other number in the set. Therefore, the correct answer is 4. Choice A (2), B (3), and D (5) do not appear as frequently as 4 in the data set, so they are not the mode.
