1. Tissues are groups of cells with similar:

Correct answer: B

Rationale: Tissues are groups of cells that work together to perform a specific function. They have similar structures that enable them to carry out their specialized functions effectively. Therefore, tissues are defined by both their function and structure, making option B the correct choice. Choices A, C, and D are incorrect because tissues are not solely defined by their appearance, location, or age, but rather by the shared function and structure of the cells within them.

2. Which of the following is NOT a characteristic of a chemical reaction?

Correct answer: C

Rationale: A change in color is not always a characteristic of a chemical reaction. While some chemical reactions may result in a change in color, it is not a universal characteristic of all chemical reactions. The formation of new substances, release or absorption of energy, and change in temperature are commonly associated with chemical reactions. Therefore, the correct answer is C, as it does not always occur in every chemical reaction.

3. Which property of matter refers to the measure of the force of gravity acting on an object?

Correct answer: B

Rationale: The correct answer is 'Weight.' Weight is the measure of the force of gravity acting on an object. Mass 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 an object occupies. In this context, the question specifically asks for the property related to the force of gravity, making 'Weight' the correct choice. 'Mass' is the measure of the amount of matter in an object, 'Density' is the mass per unit volume of a substance, and 'Volume' is the space occupied by an object, none of which directly measure the force of gravity on an object.

4. Blood is carried away from the heart in large vessels known as which of the following?

Correct answer: A

Rationale: The correct answer is A: Arteries. Arteries are the large blood vessels that carry blood away from the heart to various parts of the body. They have thick, muscular walls to withstand the high pressure generated by the heart's pumping action. Choice B, Arterioles, are smaller branches of arteries that further divide into capillaries. Choice C, Veins, carry blood back to the heart and have thinner walls compared to arteries. Choice D, Venules, are smaller veins that collect blood from capillaries and merge into larger veins.

5. What property of a wave determines its pitch in sound waves?

Correct answer: B

Rationale: The pitch of a sound wave is determined by its frequency. Frequency is the number of cycles of a wave that occur in a unit of time, usually measured in hertz (Hz). Higher frequencies correspond to higher pitches, while lower frequencies correspond to lower pitches. Amplitude refers to the height of a wave and is related to the loudness of the sound. Wavelength is the distance between two consecutive points in a wave that are in phase, and speed is the rate at which a wave travels through a medium. Therefore, the correct answer is frequency as it directly correlates with the pitch of a sound wave.
