1. Which force opposes the relative motion between surfaces in contact?

• A. Tension force
• B. Frictional force
• C. Gravitational force
• D. Magnetic force

Correct answer: b

Rationale: Friction is the force that opposes motion between surfaces in contact.

2. Which sentence uses the pronoun "they" correctly?

• A. Her friends told her they liked her new haircut.
• B. Sarah and I, they went to the movies.
• C. They gave the awards to whomever deserved them.
• D. The birds, they were singing in the trees.

Correct answer: A

Rationale: Option A agrees with the closest noun, "friends."

3. What describes the change in direction of light when it passes through different mediums, such as air and water?

• A. Diffraction
• B. Reflection
• C. Refraction
• D. Dispersion

Correct answer: c

Rationale: Refraction is the bending of light as it passes from one medium to another with different optical densities, causing a change in direction.

4. The process by which an organism adapts to its environment through inherited traits is known as

• A. Acclimatization
• B. Behavioral ecology
• C. Natural selection
• D. Niche partitioning

Correct answer: C

Rationale: Rationale: A) Acclimatization refers to the short-term physiological adjustments an individual organism makes in response to changes in its environment. This process is reversible and does not involve inherited traits. B) Behavioral ecology is the study of how behavior contributes to an organism's survival and reproduction in its environment. While behavior can be influenced by natural selection, it is not the process by which an organism adapts through inherited traits. C) Natural selection is the process by which organisms with advantageous traits for their environment are more likely to survive, reproduce, and pass on those traits to their offspring. Over time, this leads to the adaptation of populations to their environments. D) Niche partitioning is the process by which species divide resources to reduce competition within an ecosystem. While this can influence the evolution of species, it is not the process by which an organism adapts through inherited traits.

5. The process by which a single-celled organism divides into two identical daughter cells is called

• A. Conjugation
• B. Binary fission
• C. Endocytosis
• D. Mitosis

Correct answer: B

Rationale: Rationale: A) Conjugation is a process in which genetic material is transferred between two bacterial cells through a conjugation tube. It does not involve the division of a single-celled organism into two identical daughter cells. B) Binary fission is the process by which a single-celled organism, such as a bacterium, divides into two identical daughter cells. This is a common method of reproduction in prokaryotic organisms. C) Endocytosis is a cellular process in which cells engulf external materials by wrapping them in a vesicle. It is not a method of cell division. D) Mitosis is a type of cell division that occurs in eukaryotic cells, leading to the production of two daughter cells with identical genetic material. However, the question specifically refers to a single-celled organism, which typically undergoes binary fission for reproduction.

6. Identify the incorrect usage of punctuation in the following sentence: "The children, eager to play, ran outside. It was a beautiful day."

• A. comma after "children"
• B. comma after "play"
• C. period after "outside"
• D. no errors

Correct answer: C

Rationale: The two sentences are independent clauses and should be separated by a semicolon or period, not a comma.
