Answer:
Myelination
Explanation:
The white matter is the tissue present in the brain which is composed of the neurons enclosed in the myelin sheath. The presence of the myelin sheath gives white colour to the matter.
The cognitive process like the new experiences and learning ability is the result of the myelination process which forms a myelin sheath around the axon of the neuron.
The formation of the myelin sheath provides insulation and increase the speed of transmission in the neurons allows us to think and learn new things.
Thus, Myelination is the correct answer.
Folate deficiency<span> is a </span>low level<span> of the type of Vitamin B "</span>folic<span> acid" in the body. </span>
<span>Anemia, certain medicines, d</span>rinking too much alcohol, eating overcooked fruits and vegetables and other factors can contribute to folate deficiency.
So, it is true that p<span>regnant women who smoke or abuse alcohol during their pregnancy often have folate deficiencies. That;s why p</span>regnant women should be counseled about the risks of smoking and alcohol and drug use.
Answer: The Generalised Slowing Hypothesis Theory
Explanation:
The Generalised Slowing Hypothesis is built upon wide observations in many studies of age related slowing and suggests that it is the primary contributor to the declines in cognitive functioning seen with aging.
As people age, B lymphocytes and T lymphocytes become less active. These cells secrete antibodies and are thus crucial to the immune system. T cells are made in the thymus which shrinks as aging occurs. Thus reducing the body's ability to fight infections as aging occurs.
Through the normal aging process, DNA is damaged by environmental factors such as pollutants and toxic agents. As a result, there is deletions of genetic material and mutations in DNA replicated in new cells. Reduced functioning in cells and tissues occur when these errors accumulate.
Also as aging occurs, glucose molecules attach themselves to proteins and form cross links. These crosslinks reduce the flexibility of tissues making them become stiff. The circulatory systems becomes less efficient since the tissues of the lungs, heart and arteries lose flexibility.
Physical training that involves lifting weights for resistance.
The answer is C. Protein is what helps your hair, skin, and nails grow.
