Exercise lowers modest amounts of blood glucose and boosts the body's sensitivity to insulin.
Blood glucose is the concentration of sugar dissolved in the blood of a person. It is the prime source of energy for the body. When the blood glucose is very high, the person is likely to be diabetic. Exercise is necessary to burn the excessive glucose molecules in order to gain energy for the exercise.
Insulin is a polypeptide which regulates the glucose levels in the body. It is secreted by the pancreatic cells called Islets of Langerhans. The structure is composed of two chains: A chain and B chain, joined together by the disulfide bonds.

Answer:
They are stimulated by an antigen.
Explanation:
Natural killer cells are cytotoxic cells that help our body in innate immune response. These are an critical and important component of the innate immune system of our body. These natural killer cells provide a rapid response towards the virus infected cells. These cells have capability to detect MHC that are present on the infected cells. Natural killer cells do not require activation for killing those cells which are missing MHC I. Due to this feature, they are named as the Natural killer cells. These cells can directly induce the death of tumor cells and play an important role in immunosurveillance.

D) The
blue parrot population has likely increased in the last 200 years.
The answer is B. This is because the graph shows the highest number of green parrots in the 'deep forest' category of environment, whereas the numbers in the 'grassland' and 'scrub forest' are less. Since the forested area in Brazil has decreased rapidly, this means that the preferred environment of the green parrot has decreased, probably resulting in a decline in the green parrot population
