Answer:
a. Fiber
Explanation:
The major nutrients required by humans in food are carbohydrates, proteins, fats, vitamins, and minerals. Our food also has dietary fibers and water. Dietary fibers or fibers are also known as roughage. Fibers are present mainly in plant products such as whole grains, pulses, fruits and vegetables. Fibers only add bulk and do not provide any nutrients to us. However, dietary fibers help the body get rid of undigested food.

- The symptoms of illness anxiety disorder include; Excessive worry over having or getting a serious illness, physical symptoms are not present or if present, only mild, fear of illness which is normally not due to another mental disorder and excessive health-related behaviors.
Answer;
-Reduce the chance of errors in correspondence
-Easier to use for converting between units while measuring
-Make communication easier between scientists comparing data
Explanation;
-The metric system is a system that is based on joining one of a series of prefixes, including kilo-, hecto-, deka-, deci-, centi-, and milli-, with a base unit of measurement, such as meter, liter, or gram.
-Since the metric system is a decimal system of weights and measures it is easy to convert between units simply by multiplying or dividing by 10, 100, 1000, etc.
-It is an alternative system of measurement used in most countries, as well as in the United States.
Answer:
When you sit on a plane for 6 hours without moving, blood accumulates in your veins, and the moment you get up, gravitational forces affect venous return, cardiac output, blood pressure, and venous pressure. That way, when you're sitting on a plane, the gravitational force is the same at the upper and lower extremities, such as the chest, abdomen, and legs, causing venous blood pressure and volume to be evenly distributed throughout the body. However, when one gets up, one becomes dizzy because of abnormal regulation of blood pressure. This is because gravity causes blood to accumulate in the lower extremities (veins of the legs and trunk). This lowers the blood pressure and the blood that the heart pumps. By causing blood to accumulate in the lower extremities, and as venous compliance increases, the veins expand with blood that causes the volume of blood to shift in the veins. This increases the volume and venous pressure in the lower extremities when standing. And the volume of thoracic venous blood is less and less central venous pressure. This leads to a decline in stroke volume. Cardiac output and mean arterial pressure also decrease as left ventricular stroke volume decreases, reducing pulmonary venous return. Decreased standing blood pressure, referred to as orthostatic or postural hypotension. Thus, lowering blood pressure decreases cerebral blood flow, which means less range of blood in the brain causing dizziness.
