Answer is D. a two-neuron motor pathway.
Explanation:
The reflex that involves the sensory neurons connecting sensory receptors to the CNS and motor neurons that connect to the skeletal muscle is known as somatic reflex, while the autonomic reflex is the reflex involving the visceral effector, e.g cardiac muscle.
The beauty of plants being the reason for faster blooming cannot be tested using the scientific method.
<h3>The scientific method</h3>
It is a rational order of steps through which scientific investigations are conducted.
Beauty is a relative term and can be generally subjective. What is beautiful to one person might not be beautiful to others.
If we say that the lilies bloomed first before the asters because they are more beautiful, it will be difficult to categorize beauty into a metric variable, and thus, cannot be scientifically tested.

Answer: b. the output of a system keeps conditions within the body absolutely constant only in a negative feedback loop.
Explanation:
In the negative feedback loop, the feedback reduces the excessive response of the stimulus for example regulation of body temperature, and control of blood glucose level. In the positive feedback loop, the response of a stimulus is intensified. Example, positive feedback is the childbirth and blood clotting. According to the negative feedback loop the output of the system keeps the internal body environment constant with respect to the changes in the external environment hence, maintains the homeostasis.
