1. What is the process by which muscle tissue wastes away due to disuse or lack of nutrients?

Correct answer: B

Rationale: Atrophy is the correct term for the process by which muscle tissue wastes away due to disuse or lack of nutrients. It is essential to differentiate atrophy from hypertrophy, which is the increase in muscle size due to exercise or strength training. Fibrosis involves the formation of excess fibrous connective tissue, which is distinct from muscle wasting. Rigor mortis, on the other hand, is the stiffening of muscles that occurs after death and is not related to muscle wasting during life.

2. What is the scientific unit used to measure the radioactivity of a substance?

Correct answer: A

Rationale: The correct answer is A: Becquerel (Bq). The Becquerel (Bq) is the scientific unit used to measure the radioactivity of a substance. It is named after Henri Becquerel, who discovered radioactivity. The Joule (J) is the unit of energy, Newton (N) is the unit of force, and Kelvin (K) is the unit of temperature. When measuring radioactivity, the Becquerel is used to quantify the rate of radioactive decay in a substance. Choices B, C, and D are incorrect as they represent units for energy, force, and temperature, respectively, not radioactivity.

3. The speaker addresses his audience as 'My Good Friends.' What kind of credibility does this salutation give to the speaker?

Correct answer: B

Rationale: The speaker's address of 'My Good Friends' implies a sense of warmth and familiarity, indicating that the speaker wants to establish a connection with the audience before delivering a serious speech. This type of salutation is often used by entertainers to engage the audience and create a friendly atmosphere conducive to effective communication. Choice A is incorrect because there is no indication of an employer-employee relationship. Choice C is incorrect as there is no indication of irony in the salutation. Choice D is incorrect as the salutation aims to create a connection rather than grab attention as a politician might.

4. Which term describes the quantity of matter in an object and is measured in kilograms or grams?

Correct answer: B

Rationale: Mass is the quantity of matter in an object and is commonly measured in kilograms or grams. It is a fundamental property of matter and remains constant regardless of the object's location. Weight, in contrast, refers to the force of gravity acting on an object and is measured in newtons. Volume represents the amount of space an object occupies and is typically measured in cubic units like cubic meters or cubic centimeters. Density, on the other hand, is the mass of an object per unit volume, and its unit is, for example, kilograms per cubic meter. Therefore, the correct answer is 'Mass' as it specifically describes the quantity of matter in an object, regardless of the gravitational pull on it. 'Weight,' 'Volume,' and 'Density' do not directly represent the quantity of matter in an object but rather different properties related to it.

5. What is a reaction between an acid and a base known as?

Correct answer: B

Rationale: The correct answer is B: Neutralization. When an acid and a base react, they neutralize each other's properties, resulting in the formation of water and a salt. Choice A, 'Precipitation,' refers to the formation of a solid from a solution during a chemical reaction. Choice C, 'Oxidation-reduction,' involves the transfer of electrons between reactants. Choice D, 'Photolysis,' is a reaction where a compound is broken down into smaller components by light energy. Therefore, the most appropriate term for a reaction between an acid and a base is neutralization.
