1. What is the milky-white fluid transported by the lymphatic vessels called?

Correct answer: C

Rationale: The milky-white fluid transported by the lymphatic vessels is called chyle. Chyle is formed in the small intestine during the digestion of fatty foods and contains a mixture of lymph and emulsified fats. Plasma is the liquid component of blood, not lymphatic fluid. Blood refers to the fluid that circulates in the cardiovascular system, not lymphatic fluid. Mucus is a slimy substance secreted by mucous membranes, not the fluid transported by lymphatic vessels.

2. What property of a substance remains constant regardless of changes in its location in the universe?

Correct answer: A

Rationale: Mass is the amount of matter in an object and remains constant regardless of its location in the universe. Weight, on the other hand, is the force of gravity acting on an object and can vary depending on the gravitational pull at different locations. Density and volume can change based on the conditions the substance is in, so they are not constant properties. Therefore, the correct answer is mass as it does not change with changes in location.

3. What happens to the work done on an object when the angle between the force and displacement is 90 degrees?

Correct answer: B

Rationale: When the angle between the force and displacement is 90 degrees, the work done is given by the formula W = F * d * cos(theta), where theta is the angle between the force and displacement vectors. Since cos(90 degrees) = 0, the work done becomes zero. This means that no work is done on the object when the angle between the force and displacement is 90 degrees. Choice A is incorrect because maximum work is done when the force and displacement are in the same direction (theta = 0 degrees). Choice C is incorrect as minimum work is done when the force and displacement are parallel (theta = 0 degrees), not perpendicular. Choice D is incorrect because work cannot be infinite; it depends on the force, displacement, and the cosine of the angle between them.

4. Which of the following is a risk factor for developing kidney stones?

Correct answer: C

Rationale: Having a family history of kidney stones is a risk factor for developing kidney stones. Genetic predisposition can increase the likelihood of developing kidney stones due to inherited traits that affect the body's ability to process and excrete certain substances. Consuming a diet rich in fruits and vegetables (option A) and maintaining adequate hydration with water (option B) are actually recommended strategies to help prevent kidney stones by promoting overall kidney health. Regularly engaging in moderate exercise (option D) can also be beneficial for kidney health by promoting circulation and overall well-being. Therefore, options A, B, and D are not risk factors but rather beneficial for kidney health.

5. Which element shares the same group (family) on the periodic table with helium (He)?

Correct answer: A

Rationale: Elements within the same group share similar electron configurations in their outermost shells, resulting in comparable chemical properties. Helium and Neon both belong to Group 18 (Noble Gases), explaining their similarities. Boron, Carbon, and Oxygen are not in the same group as Helium on the periodic table. Boron is in Group 13, Carbon is in Group 14, and Oxygen is in Group 16, which are different from Helium's Group 18.
