Question 1 of 5

What is the relationship between mass and weight on Earth's surface?

Correct Answer: C

Rationale: The correct answer is C: Weight is greater than mass. Mass is a measure of the amount of matter in an object, while weight is the force of gravity acting on that object. On Earth's surface, weight is greater than mass because gravity pulls objects towards the center of the Earth, resulting in a force that we perceive as weight. Choice A is incorrect because mass and weight are not equal; weight is a force, while mass is a measure of the amount of matter. Choice B is incorrect because mass is not greater than weight; weight is the force exerted due to gravity. Choice D is incorrect as mass and weight are related; weight is dependent on mass and the gravitational force acting on the object.

Question 2 of 5

Where in the cell are proteins modified, sorted, and packaged for transport?

Correct Answer: B

Rationale: The Golgi apparatus is the cellular organelle responsible for modifying, sorting, and packaging proteins for transport within the cell or for secretion outside the cell. Ribosomes are not involved in modifying, sorting, or packaging proteins; they are responsible for protein synthesis. The endoplasmic reticulum (ER) is primarily involved in protein synthesis and folding, rather than modification and packaging for transport. Lysosomes function in breaking down cellular waste rather than modifying, sorting, or packaging proteins for transport.

Question 3 of 5

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

Correct Answer: A

Rationale: Mass is a measure of the amount of matter in an object and remains constant regardless of changes in gravity. Weight, on the other hand, is the force of gravity acting on an object and can vary depending on the strength of gravity. Volume is the amount of space an object occupies, and density is the mass per unit volume of a substance, both of which can change with changes in gravity. Therefore, mass is the property that remains the same regardless of variations in gravitational force. Choice B, Weight, changes with gravity as it is a force dependent on gravity. Choices C and D, Volume and Density, can be affected by changes in gravity as they are related to the space an object occupies and the mass per unit volume, respectively.

Question 4 of 5

What is the name of the cartilage flap that covers the trachea during swallowing, preventing food from entering the airway?

Correct Answer: A

Rationale: The correct answer is A: Epiglottis. The epiglottis is a cartilage flap located at the base of the tongue that covers the trachea during swallowing. Its primary function is to prevent food and liquids from entering the airway and instead directs them towards the esophagus. The glottis (choice B) refers to the space between the vocal cords in the larynx. The larynx (choice C) is the voice box containing the vocal cords responsible for phonation. The pharynx (choice D) is the throat region connecting the mouth and the esophagus, playing a role in both digestion and respiration.

Question 5 of 5

Following successful heart transplant surgery, the patient's body will need to take medications to:

Correct Answer: A

Rationale: After heart transplant surgery, the patient's body will need to take medications to suppress the immune system and prevent rejection of the new heart. This is essential to ensure that the body does not identify the transplanted heart as a foreign entity and mount an immune response against it, which could lead to transplant rejection and failure. Choices B, C, and D are incorrect because post-heart transplant medications primarily focus on preventing rejection by suppressing the immune system, rather than reducing blood pressure, dissolving blood clots, or stimulating the growth of new heart tissue.
