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.
Answer:
False.
Explanation:
RPE is basically the scale on how hard an exercise is. Here is how it works:
10 RPE: Very hard, excruciating pain.
9 RPE: Not as hard as 10, but still extremely hard.
And so on, until you reach 1, which is basically the easiest thing you've ever done in your life.
So all in all, RPE is just a scale on how hard an exercise is.
The placenta, the umbilical cord, and the amniotic sac.
Answer:
joint implant- is embedded in bones
insulin pump- automatically delivers insulin
glucose meter- requires only a small amount of blood
A) Due to the joining of the two gametes (sperm cell and egg which both have 23 chromosomes, the fertilised egg has 46 chromosomes) and because a skin cell is a normal cell (not a sex cell) it has 46 chromosomes.
You can automatically eliminate choice B because a zygote is the name for the cell produced when a sperm cell and egg joins, meaning it now has both 23 chromosomes from each of the sex cells, meaning it has 46 chromosomes. Sperm cells only ever have 23 chromosomes.
