Correct Answer: C

Rationale: The correct answer is C: An inference. This statement involves drawing a conclusion based on evidence, rather than directly observing the fact. The conclusion that someone must have forgotten to water the flower is inferred from the observation that the flower is dead. It goes beyond simple observation (Choice B) and does not involve categorizing or grouping (Choice A) or collecting items (Choice D). Inference involves using reasoning and evidence to make an educated guess or interpretation, which fits the scenario described in the statement.

Correct Answer: D

Rationale: Certainly! The correct answer is D because synergists assist primary movers (A), stabilize the point of origin while providing extra pull near the insertion (B), and help prevent unwanted movement at a joint (C). Synergists work together with the primary mover to facilitate smooth and efficient movement. Option A explains how synergists assist the primary movers in completing specific movements by adding force. Option B highlights the role of synergists in stabilizing the origin and providing additional force near the insertion point. Option C emphasizes that synergists help to stabilize the joint, preventing unnecessary movements and ensuring proper execution of the desired motion. Therefore, all the options (A, B, and C) collectively describe the functions of synergists, making option D the correct choice.

Correct Answer: C

Rationale: The somatic nervous system is responsible for voluntary movement of skeletal muscles. It controls conscious movements like walking, writing, or speaking. This system does not regulate automatic functions like breathing (option A), cognitive processes like thought (option B), or emotional responses like fear (option D). Therefore, the correct answer is C - Movement.

Correct Answer: C

Rationale: The correct answer is C (3). In a typical sensory pathway, there are three neurons involved: the primary sensory neuron, secondary sensory neuron, and tertiary sensory neuron. The primary sensory neuron transmits signals from the sensory receptor to the spinal cord or brainstem. The secondary sensory neuron carries the signal from the spinal cord or brainstem to the thalamus in the brain. Lastly, the tertiary sensory neuron carries the signal from the thalamus to the sensory cortex for processing. Therefore, a sensory pathway typically comprises three neurons to relay sensory information from the periphery to the brain. Choice A (1) is incorrect because sensory pathways involve multiple neurons for signal transmission. Choice B (2) is incorrect as it does not account for the tertiary sensory neuron involved in the pathway. Choice D (4) is incorrect because the typical sensory pathway consists of three neurons, not four.

Correct Answer: B

Rationale: The final phase of mitosis is Telophase. In Telophase, the nuclear envelope reforms around the separated chromatids, chromosomes unwind into chromatin, and the nucleolus reappears. This marks the end of nuclear division. Prophase is the initial phase where chromosomes condense. Anaphase is when chromatids separate and move to opposite poles. Metaphase is when chromatids align at the center. Telophase is the only phase where the nuclear envelope reforms and the nuclear division is completed.
