Biology

1. Which of the following is the main function of the lungs?

Correct answer: D

Rationale: Rationale: A) To transport oxygen and nutrients throughout the body - While the lungs do play a role in transporting oxygen, their primary function is to exchange oxygen and carbon dioxide between the body and the environment. The transportation of oxygen and nutrients throughout the body is primarily carried out by the circulatory system, specifically the blood vessels. B) To coordinate movement and sensory information - This function is primarily carried out by the nervous system, specifically the brain and spinal cord. C) To filter waste products from the blood - The kidneys are responsible for filtering waste products from the blood, not the lungs. The lungs primarily function in gas exchange.

2. In the reaction 4Al + 3O2 → 2Al2O3, what is the mole ratio of aluminum to oxygen?

Correct answer: a

Rationale: The coefficients in the balanced equation represent the mole ratio, which is 4 moles of Al to 3 moles of O2.

3. The final sentence suggests that the debate surrounding UBI necessitates

Correct answer: C

Rationale: The emphasis on "complex interplay" and "careful consideration" suggests a call for nuanced and multifaceted discussions, aligning with C.

4. The process of a liquid changing into a gas is called:

Correct answer: A

Rationale: Evaporation occurs at any temperature, while boiling only occurs at the boiling point of the liquid.

5. Which of the following is NOT a major division of the nervous system?

Correct answer: C

Rationale: The somatic nervous system is actually a component of the peripheral nervous system, responsible for voluntary control of skeletal muscles and sensory information. The major divisions of the nervous system are the central nervous system (which includes the brain and spinal cord) and the peripheral nervous system (which includes all nerves outside the central nervous system). The autonomic nervous system, on the other hand, is a division of the peripheral nervous system responsible for involuntary functions like heart rate and digestion. Therefore, the correct answer is C, the somatic nervous system, as it is not a major division of the nervous system.

6. Where does cellular respiration, the process of converting chemical energy into ATP, take place in eukaryotic cells?

Correct answer: C

Rationale: Rationale: Cellular respiration, the process of converting chemical energy into ATP, takes place in the mitochondria of eukaryotic cells. The mitochondria are known as the powerhouse of the cell because they are responsible for generating most of the cell's ATP through the process of cellular respiration. This process involves the breakdown of glucose and other organic molecules to produce ATP, which is the primary energy currency of the cell. The other organelles listed in the options (nucleus, ribosomes, and Golgi apparatus) do not play a direct role in cellular respiration.
