Anatomy

1. What is the structure that connects the ovary to the uterus in the female reproductive system?

Correct answer: B

Rationale: The correct answer is B: Fallopian tube. The fallopian tubes are the structures that connect the ovaries to the uterus in the female reproductive system. These tubes play a crucial role in the fertilization process by providing a pathway for the egg to travel from the ovary to the uterus. The urethra (A) is a structure that carries urine from the bladder out of the body and is not directly involved in the reproductive system. The vagina (C) is the canal that connects the external genitals to the cervix and is not the structure that connects the ovary to the uterus. The cervix (D) is the lower part of the uterus that connects to the vagina and does not connect the ovary to the uterus.

2. A convex lens is characterized by its ability to:

Correct answer: A

Rationale: The correct answer is A: 'Converge light rays.' A convex lens is thicker in the center and thinner at the edges, causing light rays passing through it to converge or come together at a focal point. This ability is what enables convex lenses to bend light rays inward, focusing them to produce clear images. Options B and C are incorrect because convex lenses do not diverge light rays or focus sound waves. Option D is also incorrect as convex lenses can create both real and virtual images based on the position of the object with respect to the lens. Therefore, the main characteristic of a convex lens is its ability to converge light rays to form focused images.

3. Identify the conjunction in the following sentence: He went to the store, but they were already closed.

Correct answer: C

Rationale: Conjunctions connect words, phrases, or clauses. "But" joins two contrasting ideas in the sentence.

4. Which organ helps break down food by grinding it with your teeth?

Correct answer: D

Rationale: Rationale: The mouth is the organ that helps break down food by grinding it with your teeth. The process of chewing, also known as mastication, breaks down food into smaller pieces, making it easier to swallow and digest. The teeth in the mouth play a crucial role in this initial stage of digestion by physically breaking down food into smaller particles. The other options listed do not directly participate in the mechanical breakdown of food through chewing.

5. Fingernails and toenails are made primarily of:

Correct answer: B

Rationale: The correct answer is B: Keratin. Fingernails and toenails are primarily made of a tough protein called keratin. Keratin is a fibrous structural protein that also makes up hair and the outer layer of skin. Collagen, as mentioned in option A, is found in the dermis of the skin and is responsible for providing strength and elasticity to the skin. Melanin, as in option C, is a pigment that gives color to the skin, hair, and eyes, but it does not contribute to the structure of nails. Sebum, as in option D, is an oily substance produced by the sebaceous glands in the skin to moisturize and protect the skin, but it is not a component of nails.

6. Which property of a substance remains constant regardless of changes in its shape or size?

Correct answer: a

Rationale: Mass is the measure of the amount of matter in an object and remains constant regardless of changes in its shape or size.
