1. What is the role of the kidneys in the body?

• A. To regulate body temperature
• B. To filter waste from the blood
• C. To produce hormones
• D. To transport oxygen

Correct answer: B

Rationale: The correct answer is B: To filter waste from the blood. The kidneys play a crucial role in filtering waste products and excess substances from the blood to form urine, which helps maintain fluid balance and eliminate toxins from the body. Choice A is incorrect because regulating body temperature is primarily controlled by the skin and other mechanisms. Choice C is incorrect as hormone production is mainly attributed to other organs like the endocrine glands. Choice D is incorrect as the transportation of oxygen is primarily facilitated by the lungs and circulatory system, not the kidneys.

2. What is the study of fungi known as?

• A. Virology
• B. Mycology
• C. Bacteriology
• D. Parasitology

Correct answer: B

Rationale: Mycology is the correct answer. Mycology is the branch of biology that specifically deals with the study of fungi. Fungi constitute a separate kingdom of organisms that include various forms such as yeasts, molds, and mushrooms. Virology (A) is the study of viruses, while Bacteriology (C) focuses on bacteria. Parasitology (D) is the study of parasites, which may include protozoa, helminths, and some fungi, but it is not solely dedicated to fungi.

3. Which property of matter measures the amount of space occupied by an object?

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

Correct answer: D

Rationale: Volume is the property of matter that measures the amount of space occupied by an object. Mass refers to the amount of matter in an object, weight is the force of gravity acting on an object, and density is the mass of an object per unit volume. Volume specifically quantifies the space occupied by an object, making it the correct answer in this context.

4. Which of the following bones belongs to the category of long bones?

• A. Femur
• B. Ribs and cranial bones
• C. Sesamoid
• D. Vertebrae and hip bones

Correct answer: A

Rationale: The correct answer is A: Femur. Long bones are characterized by their elongated shape, with examples including the femur, humerus, and tibia. These bones are essential for support, movement, and bone marrow production. Choice B, 'Ribs and cranial bones,' consists of flat bones, not long bones. Choice C, 'Sesamoid,' refers to small bones embedded within tendons and do not fall under the category of long bones. Choice D, 'Vertebrae and hip bones,' includes irregular bones that provide structural support and protection for vital organs, but they are not classified as long bones.

5. Which of the following are properties of a liquid?

• A. High atomic attraction
• B. Fixed volume
• C. Low pressure
• D. Takes shape of container

Correct answer: D

Rationale: The correct answer is D: 'Takes shape of container.' Liquids exhibit the property of taking the shape of their container while maintaining a fixed volume. This is due to the ability of liquid particles to flow and move freely within the container. Choices A, B, and C are incorrect. Choice A, 'High atomic attraction,' is not a general property of liquids as the level of attraction between liquid particles can vary. Choice B, 'Fixed volume,' is partially correct as liquids do have a fixed volume, but they do not have a fixed shape. Choice C, 'Low pressure,' is not a defining property of liquids.
