D.
The block of wood does not stop moving at any time as shown on the chart, so the answer can't be A. or C. and the speed is not increasing so it can't be B.
Answer:
Santi is walking barefoot through his yard when he steps on a sharp rock. The skin on the bottom of his foot sends this information through a(n) <em>sensory</em> neuron to his CNS. A(n) <em>interneuron</em> picks up this information and carries it to <em>motor neurons of the CNS</em>, which sends a signal to the muscles in his foot causing his foot to pull away from the rock.
Explanation:
The scenarios discussed in the question is known as a reflex action. In this action, specific receptors detect specific stimuli. For example, pain in the barefoot due to steeping on a sharp rock was the stimuli. This stimulus was detected by the sensory neurons. The sensory neurons turned this information into a chemical signal which was transported by the interneurons to the motor neurons of the CNS. The CNS detected the signal and gave information for a response as a result of which Santi pulled back his feet.
So the process involves copying the chromosomes first and then carefully separating the copies to give each new cell a full set
