The right answer is D (less responsive to antigens)
It is proven that, after puberty, thymus activity (an organ that is included in the lymphatic system, producing T cells that pick up antigens) decreases and that in adult and aged people the thymus has no role. Work done in humans indicate that in fact the cellularity begins to decline from birth in favor of lymphocyte perivascular spaces and connective and adipose tissue, which leads to a decrease in the capture of antigens.
<u>Sensory neuron to motor neuron</u> are specifically responsible for the habituation of the withdrawal response.
- The withdrawal reflex, which is the automatic withholding of a limb from a painful stimulation, is what is known as this automatic reaction.
- Humans are shielded by this reflex from tissue necrosis brought on by exposure to noxious stimuli like pain or heat. Either the upper or lower limbs may experience it.
- A somatic reflex, like the withdrawal reflex, and a visceral reflex, an autonomic reflex, differ in that the latter has an efferent branch.
- The lower motor neuron in the ventral horn of the spinal cord, which immediately projects to a skeletal muscle to produce its contraction, is the output of a somatic reflex.

<span>There have been studies done that show using this technology to create milk makes the milk more dangerous. People who drink this milk are more likely to get prostate cancer, breast cancer and colon cancer. The technology also creates many toxins that can harm the cows and milk drinkers.</span>
