Answer:
Dehydration
Explanation:
Dehydration is the condition of the body which involves the loss of body fluid compared to the amount of water the body gets. Water is an important constituent of the human body making up to about two-third of the body. The normal body metabolism is affected when the amount of water in the body drops below the required level of water necessary for optimal functioning of the body.
Athletes usually suffer from dehydration, most especially long distance runners, as they tend to lose a lot of body fluid through sweating while the body tries to regulate the body temperature during the race. When the body is dehydrated, the heart works harder to pump blood to various parts of the body leading to loss of strength of the muscles.
Common signs a dehydrated person shows include feeling tired and lightheaded, loss of body weight etc.
Answer:
A. Molecular changes such as extracellular signals on extracellular ligands can result in quick changes in cell behaviour. One example is insulin. Upon insulin binding on the receptor on the cell membrane, the cell release GLUT4 transporters (for muscle cells) to increase uptake of glucose.
B. Slow changes in cell behaviour can be observed for other lipophilic hormones or intracellular receptors such as glucocoortoid or estrogen which reacts with receptors in the cells.
C. Insulin is required to maintain a constant blood glucose level and hence levels of insulin has to be mediated in correspondence to the blood glucose levels. Fast acting signalling is thus required for homeostasis of blood glucose levels. Where for such lipophilic hormones such as steriods, glucocortoid, these hormones tend to have a longer lasting effect and hence results in a slow change.
When a child has celiac<span> disease<span>, his body has a major problem with </span>gluten. Damage is done to the lining of his small intestine when any food containing gluten –are ingested. </span>
<span>It is a lifelong condition where there is no known medicine to cure, although a happy and normal life is said to be possible with proper management. The only treatment to follow is a gluten-free diet. Gluten includes wheat, barley, and rye which is nearly impossible to completely remove from a child’s diet. Parents need to be aware also of hygiene products especially when bathing young children.</span>
