Question 1 of 9

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

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.

Question 2 of 9

Which vitamin deficiency can lead to kidney stones?

Correct Answer: C

Rationale: The correct answer is Vitamin D. Vitamin D deficiency can lead to kidney stones because Vitamin D helps regulate calcium levels in the body. Low levels of Vitamin D can result in increased calcium absorption from the intestines, leading to higher levels of calcium in the urine, which can form kidney stones. Choices A, B, and D are incorrect as deficiencies in these vitamins are not directly associated with kidney stone formation.

Question 3 of 9

Which type of glial cell provides structural support and insulation for neurons in the central nervous system?

Correct Answer: C

Rationale: Oligodendrocytes are a type of glial cell that provides structural support and insulation for neurons in the central nervous system by forming myelin sheaths around axons. Schwann cells (option A) perform a similar function but in the peripheral nervous system. Astrocytes (option B) are involved in providing nutrients to neurons, maintaining the chemical environment, and repairing damage. Microglia (option D) are primarily responsible for immune defense in the central nervous system, not for providing structural support and insulation for neurons.

Question 4 of 9

What is the relationship between work, force, and displacement?

Correct Answer: B

Rationale: Work is directly proportional to both force and displacement. The work done on an object is calculated by multiplying the force applied to the object by the distance the object moves in the direction of the force. Therefore, work is directly proportional to both force and displacement. Choice A is incorrect because work is not inversely proportional to displacement. Choice C is incorrect because work is not inversely proportional to force. Choice D is incorrect because work is not inversely proportional to both force and displacement.

Question 5 of 9

What is the SI unit of measurement for work?

Correct Answer: B

Rationale: The correct answer is B: Joule (J). Work is defined as the amount of energy transferred by a force acting through a distance. The Joule is the unit used to measure this energy transfer. Choice A, Newton-meter (N·m), is the unit for torque, not work. Choice C, Watt (W), is the unit of power, not work. Choice D, Meter per second (m/s), is a unit for speed or velocity and is not related to work.

Question 6 of 9

Which property of a substance refers to the force exerted on an object due to gravity?

Correct Answer: B

Rationale: The correct answer is 'Weight.' Weight is the force exerted on an object due to gravity. Mass, on the other hand, refers to the amount of matter in an object. Density is the mass per unit volume of a substance, and volume is the amount of space occupied by an object. In this context, weight specifically relates to the gravitational force acting on an object, making it the most appropriate choice among the options provided.

Question 7 of 9

Which part of the respiratory system is responsible for gas exchange between the blood and inhaled air?

Correct Answer: C

Rationale: The correct answer is C, Alveoli. The alveoli are tiny air sacs in the lungs where the exchange of oxygen and carbon dioxide takes place between the air we breathe in and the blood. The trachea, larynx, and pharynx are all part of the airway passage but do not directly participate in gas exchange. The trachea serves as the windpipe, the larynx is involved in sound production and protecting the airway during swallowing, and the pharynx helps with swallowing and speech production. Therefore, the alveoli specifically facilitate the critical gas exchange process, making them the correct answer in this context.

Question 8 of 9

What is the function of a cell wall?

Correct Answer: A

Rationale: The cell wall is a rigid layer that surrounds the cell membrane in plant cells, fungi, and some bacteria. Its main function is to provide structural support and protection for the cell, helping maintain the cell's shape and preventing it from bursting or collapsing. The cell wall also allows for the passage of water, ions, and other molecules in and out of the cell. Options B, C, and D are incorrect because those functions are typically carried out by other cellular structures. Option B is performed by the cell membrane, option C by ribosomes, and option D by the nucleus, which stores genetic material.

Question 9 of 9

Classifications of human tissues exclude:

Correct Answer: D

Rationale: The correct answer is D: Bony tissue. Classifications of human tissues typically include epithelial tissue, nervous tissue, and connective tissue types such as adipose tissue. Bony tissue, also known as bone tissue, is a specialized form of connective tissue that provides structural support and protection for the body. Therefore, it is not excluded from classifications of human tissues. Choices A, B, and C are valid types of human tissues and are correctly included in classifications of human tissues.
