Anatomy

1. What is the neurotransmitter involved in muscle movement?

Correct answer: B

Rationale: The correct answer is B: Acetylcholine. Acetylcholine is the neurotransmitter involved in muscle movement. It is released by motor neurons at the neuromuscular junction to stimulate muscle contraction. Dopamine is involved in reward and pleasure pathways in the brain, serotonin plays a role in mood regulation, and GABA is an inhibitory neurotransmitter that helps to reduce neural activity. Understanding the specific roles of neurotransmitters is crucial in grasping their functions in the nervous system.

2. A ball is thrown horizontally off a cliff. Which of the following forces is responsible for its downward motion?

Correct answer: D

Rationale: The gravitational force is responsible for the downward motion of the ball. When the ball is thrown horizontally off a cliff, the only force acting on it in the vertical direction is the force of gravity, which pulls the ball downward towards the ground. The other forces mentioned (force of throwing, normal force from the air, tension force from the string) do not contribute to the ball's downward motion in this scenario.

3. The fossil record shows that dinosaurs with feathers existed millions of years before birds. This is evidence for

Correct answer: A

Rationale: Rationale: The fossil record indicating that dinosaurs had feathers before birds suggests convergent evolution. Convergent evolution occurs when unrelated organisms independently evolve similar traits to adapt to similar environmental pressures. In this case, both dinosaurs and birds developed feathers for flight or insulation purposes, even though they are not closely related. This evidence supports the concept of convergent evolution rather than divergent evolution, coevolution, or the extinction of dinosaurs due to an asteroid impact.

4. What is the process by which a large, unstable nucleus splits into two smaller nuclei, releasing neutrons and energy?

Correct answer: D

Rationale: Nuclear fission involves splitting a heavy nucleus into smaller fragments, releasing neutrons and energy.

5. The energy absorbed during a chemical reaction is called:

Correct answer: D

Rationale: Endothermic means "inward heat," indicating energy is absorbed during the reaction.

6. What is the general formula for an alkyl halide?

Correct answer: C

Rationale: The general formula for an alkyl halide is \(C_nH_{2n-1}X\), where X represents a halogen (e.g., F, Cl, Br, I).
