Anatomy

1. The peripheral nervous system can be further divided into which two main parts?

Correct answer: A

Rationale: The correct answer is A: 'Sensory and motor.' The peripheral nervous system is divided into two main parts based on their functions. The sensory division (afferent) transmits sensory information from receptors to the central nervous system, while the motor division (efferent) transmits signals from the central nervous system to muscles and glands to produce a response. Options B, C, and D are incorrect as they do not accurately describe the main divisions of the peripheral nervous system. Understanding this division is crucial in comprehending how information is processed and responses are generated in the body.

2. Which type of wave requires a medium to travel through?

Correct answer: d

Rationale: Both mechanical waves (such as sound waves) and electromagnetic waves (like light) have different requirements for propagation, but both can travel through a medium.

3. Parkinson's disease is a neurodegenerative disorder affecting which neurotransmitter?

Correct answer: A

Rationale: The correct answer is A: Dopamine. Parkinson's disease is characterized by a progressive loss of dopamine-producing neurons in the brain. Dopamine is a neurotransmitter responsible for transmitting signals in the brain that control movement and coordination. A decrease in dopamine levels leads to the typical motor symptoms of Parkinson's, such as tremors, rigidity, and bradykinesia. Acetylcholine (option B) is involved in muscle movement but is not primarily affected in Parkinson's disease. Serotonin (option C) and glutamate (option D) are neurotransmitters that play different roles in the brain and are not primarily associated with Parkinson's disease. Therefore, the correct neurotransmitter affected in Parkinson's disease is dopamine.

4. Which of the following organs is responsible for the mechanical breakdown of food into smaller pieces?

Correct answer: D

Rationale: The correct answer is D: Mouth. The mouth is responsible for the mechanical breakdown of food into smaller pieces through the process of chewing. The teeth in the mouth help to grind and crush food into smaller particles, making it easier for digestion to occur. The esophagus is a muscular tube that transports food to the stomach but does not contribute to mechanical breakdown. The stomach is responsible for further breaking down food using acid and enzymes, while the small intestine is mainly involved in the absorption of nutrients. Therefore, the mouth plays a crucial role in the initial mechanical digestion of food.

5. What is the process of breaking down fatty acids into acetyl-CoA, a key molecule in cellular respiration, called?

Correct answer: A

Rationale: Rationale: A) Beta-oxidation is the process of breaking down fatty acids into acetyl-CoA molecules. This process occurs in the mitochondria and is a crucial step in fatty acid metabolism for energy production. B) Lipolysis is the breakdown of fats into fatty acids and glycerol, but it does not specifically refer to the conversion of fatty acids into acetyl-CoA. C) Carbohydrate catabolism involves the breakdown of carbohydrates into glucose for energy production and is not directly related to the conversion of fatty acids into acetyl-CoA. D) Nucleic acid catabolism refers to the breakdown of nucleic acids into nucleotides and does not involve the conversion of fatty acids into acetyl-CoA.

6. 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.
