1. Which of the following is NOT a type of asexual reproduction in bacteria?

Correct answer: D

Rationale: A) Binary fission: This is a common method of asexual reproduction in bacteria where a single cell divides into two identical daughter cells. B) Conjugation: This is a process in which genetic material is transferred between bacterial cells through direct cell-to-cell contact, leading to genetic recombination. C) Budding: Budding is a form of asexual reproduction where a new organism develops from an outgrowth or bud on the parent organism. D) Transduction: Transduction is a method of horizontal gene transfer in bacteria where genetic material is transferred from one bacterium to another by a bacteriophage (a virus that infects bacteria). It is not a form of asexual reproduction in bacteria. Therefore, the correct answer is D) Transduction, as it is not a type of asexual reproduction in bacteria but a mechanism of genetic exchange.

2. Which property of a substance measures the amount of matter per unit volume?

Correct answer: A

Rationale: Density is the property of a substance that measures the amount of matter per unit volume. It is calculated by dividing the mass of the substance by its volume. Mass refers to the amount of matter in an object, weight is the force of gravity acting on an object, and volume is the amount of space an object occupies. Density specifically quantifies how tightly packed the matter in a substance is, providing a measure of compactness or concentration of matter. Therefore, the correct answer is A, Density.

3. Which property of a substance refers to its ability to undergo a chemical change and form new substances?

Correct answer: C

Rationale: Reactivity is the property of a substance that describes its ability to undergo a chemical change and form new substances through chemical reactions. Density, mass, and volume are physical properties of a substance and do not directly relate to its ability to undergo chemical changes. Density is the mass of a substance per unit volume, mass is the amount of matter present, and volume is the amount of space occupied by the substance. Reactivity specifically deals with how likely a substance is to engage in chemical reactions. Therefore, the correct answer is C - Reactivity.

4. Which term in physics describes the resistance of an object to changes in its motion?

Correct answer: A

Rationale: Inertia is the term that describes the resistance of an object to changes in its motion. This property is explained by Newton's First Law of Motion, which states that objects tend to maintain their state of motion unless acted upon by an external force. Inertia is closely related to mass, where objects with more mass exhibit more resistance to changes in motion. Momentum (B) is the product of an object's mass and velocity, gravity (C) is the force of attraction between objects, and kinetic energy (D) is the energy associated with an object's motion. Therefore, the correct answer is A because inertia specifically addresses the resistance of an object to changes in its motion.

5. A person pushes a box across a floor with a constant force. The box eventually comes to a stop due to friction. What happens to the work done by the person?

Correct answer: D

Rationale: Work done is defined as the product of the force applied and the distance moved in the direction of the force. In this scenario, when the box comes to a stop, the displacement becomes zero, leading to zero work done by the person. Choice A is incorrect as the work done is not increasing, but rather decreasing as the box slows down. Choice B is incorrect because the work done does not decrease as the box slows down; it becomes zero when the box stops. Choice C is incorrect as the work done is not constant but decreases to zero when the box stops.
