B) Brain...spinal cord, for some reason I keep ending up on questions you've asked.
That is TRUE because when you get older your bones and muscles start to decrease so being physically active will make your bones and muscles stronger as they decrease.
<span>Reaction time is the time from the start of the stimulus to to the beginning of movement in reaction to the stimulus. Since she has high cardiorespiratory endurance there is a greater coordination in the working of her heart, muscles and lungs. This will help her to get a good reaction time and will increase her performance level.</span>
<span>The phytonutrients in apples can help you regulate your blood sugar. Recent research has shown that apple polyphenols can help prevent spikes in blood sugar through a variety of mechanisms. Flavonoids like quercetin found in apples can inhibit enzymes like alpha-amylase and alpha-glucosidase. Since these enzymes are involved in the breakdown of complex carbohydrates into simple sugars, your blood sugar has fewer simple sugars to deal with when these enzymes are inhibited. In addition, the polyphenols in apple have been shown to lessen absorption of glucose from the digestive tract; to stimulate the beta cells of the pancreas to secrete insulin; and to increase uptake of glucose from the blood via stimulation of insulin receptors. All of these mechanisms triggered by apple polyphenols can make it easier for you to regulate your blood sugar.
hope it helped and dont forget to mark as the brainliest!</span>
