1. Which sentence avoids a dangling modifier?

• A. Walking down the street, a bird swooped down from a tree.
• B. Having finished the report, it was time for lunch.
• C. Reading the book, I learned a lot about ancient history.
• D. Exhausted from the hike, the tent was a welcome sight.

Correct answer: C

Rationale: Option C places the participle phrase "Reading the book" in front of the subject "I," eliminating the dangling modifier.

2. What happens to the wavelength of a wave when its frequency increases while the speed remains constant?

• A. Wavelength increases
• B. Wavelength decreases
• C. Wavelength remains the same
• D. Wavelength becomes zero

Correct answer: b

Rationale: When the frequency of a wave increases while the speed remains constant, the wavelength decreases.

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

• A. Density
• B. Mass
• C. Reactivity
• D. Volume

Correct answer: c

Rationale: Reactivity refers to a substance's ability to undergo chemical changes, forming new substances with different properties.

4. A clinic sees an average of 25 patients every 4 hours. If the clinic is open for 8 hours, how many patients will they see in total?

• A. 35
• B. 50
• C. 75
• D. 200

Correct answer: D

Rationale: Rationale: 1. First, determine how many patients the clinic sees in one hour: 25 patients / 4 hours = 6.25 patients per hour (approximately 6 patients per hour) 2. Since the clinic is open for 8 hours, multiply the number of patients seen per hour by the number of hours the clinic is open: 6.25 patients/hour * 8 hours = 50 patients 3. Therefore, the clinic will see a total of 50 patients in 8 hours, which corresponds to answer choice D) 200.

5. The gradual change in a species over time in response to environmental pressures is best described by:

• A. Punctuated equilibrium (rapid bursts of evolution)
• B. Gradualism (slow and continuous change)
• C. Founder effect (genetic drift in a small population)
• D. Adaptive radiation (rapid diversification of a species)

Correct answer: B

Rationale: Rationale: A) Punctuated equilibrium refers to rapid bursts of evolution followed by long periods of stability, rather than gradual change over time in response to environmental pressures. B) Gradualism is the process by which species evolve through slow and continuous changes over time in response to environmental pressures. This gradual change can lead to the development of new traits and adaptations. C) Founder effect is a type of genetic drift that occurs when a small group of individuals establishes a new population, leading to a loss of genetic variation compared to the original population. It does not specifically describe the gradual change in a species over time. D) Adaptive radiation is the rapid diversification of a species into a variety of forms to exploit different ecological niches, but it does not specifically refer to the gradual change in response to environmental pressures. Therefore, the best description of the gradual change in a species over time in response to e

6. Differentiate between epithelial and connective tissue.

• A. Epithelial tissue is exclusively found in the lungs, while connective tissue supports tendons.
• B. Both are composed of cells, but epithelial tissue lines surfaces and glands, while connective tissue binds other tissues.
• C. Epithelial tissue is more vascularized, while connective tissue is responsible for muscle contraction.
• D. Epithelial tissue is the largest tissue type, while connective tissue is the smallest.

Correct answer: B

Rationale: Epithelial tissue covers surfaces and lines organs, while connective tissue provides support and structure throughout the body. Both are composed of cells, but their functions and locations differ.
