1. Which of the following is NOT a common symptom of lactose intolerance?

• A. Gas
• B. Bloating
• C. Diarrhea
• D. Nausea

Correct answer: D

Rationale: A) Gas: Gas is a common symptom of lactose intolerance. When lactose is not properly digested, it can ferment in the colon, leading to the production of gas. B) Bloating: Bloating is another common symptom of lactose intolerance. The buildup of gas in the digestive system can cause bloating and discomfort. C) Diarrhea: Diarrhea is a common symptom of lactose intolerance. When lactose is not broken down in the small intestine, it can draw excess water into the colon, resulting in diarrhea. D) Nausea: Nausea is not a common symptom of lactose intolerance. While some individuals may experience mild stomach discomfort or cramps, nausea is not typically associated with lactose intolerance.

2. How many kilograms are in 1,800 grams?

• A. 0.18
• B. 1.8
• C. 18
• D. 180

Correct answer: B

Rationale: To convert grams to kilograms, divide by 1,000 since there are 1,000 grams in a kilogram. Therefore, 1,800 grams is equal to 1.8 kilograms (1,800 / 1,000 = 1.8). Choice A (0.18) is incorrect because it incorrectly shifted the decimal point. Choice C (18) is incorrect as it represents the direct conversion without dividing by 1,000. Choice D (180) is incorrect as it is in the hundreds and not the correct conversion to kilograms. The correct answer is B.

3. Which of the following structures is responsible for producing insulin?

• A. Liver
• B. Pancreas
• C. Gallbladder
• D. Spleen

Correct answer: B

Rationale: The correct answer is B: Pancreas. The pancreas is the organ responsible for producing insulin. Insulin is a hormone that helps regulate blood sugar levels by allowing cells to take in glucose from the bloodstream. The liver (choice A) plays a role in regulating blood sugar levels through glycogen storage and release but does not produce insulin. The gallbladder (choice C) stores bile produced by the liver to aid in digestion and has no direct involvement in insulin production. The spleen (choice D) is involved in immune function and blood storage but not in the production of insulin.

4. Which property of matter remains constant regardless of changes in gravity?

• A. Mass
• B. Weight
• C. Volume
• D. Density

Correct answer: A

Rationale: Mass is a measure of the amount of matter in an object and remains constant regardless of changes in gravity. This is because mass is an intrinsic property of an object and does not depend on the gravitational field it is in. Weight, on the other hand, is the force of gravity acting on an object's mass and can vary depending on the strength of gravity. Volume is the amount of space an object occupies, which can change depending on the environment. Density is the mass of an object per unit volume, which can also change with variations in gravity. Therefore, the correct answer is Mass as it remains the same regardless of gravitational changes.

5. What is the process by which a fertilized egg implants itself in the lining of the uterus?

• A. Fertilization
• B. Implantation
• C. Gestation
• D. Parturition

Correct answer: B

Rationale: Implantation is the correct answer. It is the process where a fertilized egg attaches itself to the lining of the uterus to establish a pregnancy. Fertilization is the initial step where the sperm and egg fuse to form a zygote. Gestation refers to the period of fetal development within the uterus. Parturition is the process of giving birth and is not related to the implantation of the fertilized egg, which occurs earlier in the reproductive process.
