1. What energy conversion occurs in a solar cell?

• A. Electrical energy to light energy
• B. Chemical energy to electrical energy
• C. Solar energy to thermal energy
• D. Solar energy to electrical energy

Correct answer: D

Rationale: Solar cells, also known as photovoltaic cells, convert solar energy from sunlight directly into electrical energy through a process called the photovoltaic effect. This process involves the absorption of photons from sunlight, which then generate an electric current. Choice A is incorrect because solar cells do not convert electrical energy into light energy. Choice B is incorrect as solar cells do not involve chemical energy conversion. Choice C is incorrect because solar cells do not primarily convert solar energy into thermal energy. Therefore, the correct answer is D) Solar energy to electrical energy.

2. A synonym for disconfirmed would be:

• A. proven
• B. dissipated
• C. distilled
• D. disproven

Correct answer: D

Rationale: The word 'disconfirmed' can be understood by breaking down 'disconfirm,' where 'dis' indicates 'not' and 'confirm' means 'to prove.' Therefore, 'disconfirmed' means 'not proven,' which aligns with the meaning of 'disproven.' In the given passage, it is mentioned that evidence can disprove a hypothesis, not necessarily prove it. This supports the synonymity between 'disconfirmed' and 'disproven.' Choice A ('proven') is incorrect because 'proven' is the opposite of 'disconfirmed.' Choice B ('dissipated') is incorrect as it means to disappear or scatter, not related to disproving a hypothesis. Choice C ('distilled') is incorrect as it means to purify a liquid through heating and cooling, not related to proving or disproving hypotheses.

3. Which of the following sentences has an error in capitalization?

• A. The East Coast has experienced very unpredictable weather this year.
• B. My uncle owns a home in Florida, where he lives in the winter.
• C. I am taking English Composition II on campus this fall.
• D. There are several nice beaches we can visit on our trip to the Jersey Shore this summer.

Correct answer: B

Rationale: The error in capitalization is in option B. 'Uncle' should not be capitalized because it is not used as a proper noun in this context. It should be written as 'uncle.' In the other options, capitalization is correctly used for proper nouns like 'East Coast,' 'English Composition II,' and 'Jersey Shore,' making them the correct choices.

4. Which organelle in the cell is responsible for producing energy in the form of ATP?

• A. Nucleus
• B. Mitochondria
• C. Ribosome
• D. Golgi apparatus

Correct answer: B

Rationale: The correct answer is B: Mitochondria. Mitochondria are known as the powerhouses of the cell and are responsible for producing energy in the form of ATP through cellular respiration. ATP is the primary energy currency of the cell, powering various cellular activities. The nucleus (choice A) is responsible for housing the cell's genetic material but is not involved in ATP production. Ribosomes (choice C) are involved in protein synthesis, not energy production. The Golgi apparatus (choice D) is responsible for modifying, sorting, and packaging proteins for secretion, not for ATP production.

5. What function do ribosomes serve within the cell?

• A. Ribosomes are responsible for cell movement.
• B. Ribosomes aid in protein synthesis.
• C. Ribosomes help protect the cell from its environment.
• D. Ribosomes have enzymes that help with digestion.

Correct answer: B

Rationale: Ribosomes serve a crucial role in protein synthesis by translating mRNA into proteins. They are not involved in cell movement, protecting the cell from the environment, or aiding in digestion. Choice A is incorrect because ribosomes are not responsible for cell movement. Choice C is incorrect because ribosomes do not primarily protect the cell from its environment. Choice D is incorrect because ribosomes do not have enzymes that aid in digestion.
