Answer:
At the Equator (0° of latitude), the North Star is on the horizon, making an angle of 0°. For any point between the Equator and the North Pole, latitude is obtained simply by measuring the altitude of Polaris: at 30°N the star is 30° above the horizon, at 63°N, it is 63° above the horizon, and so on.
Answer:
Starvation causes a reduction in the <u>oncotic</u> pressure in the <u>cappilaries</u>, thus causing edema in the tissues.
Explanation:
Starvation is the extreme form of malnutrition, in which the caloric energy intake of an individual is much lower than required. The cells of the body start the breakdown of proteins, after the fat stores get exhausted. This reduces the oncotic pressure or the colloidal pressure in the blood vessels or capillaries of the body, thereby causing edema.
Edema is a medical condition, which involves the abnormal accumulation of fluid in the interstitium and cavities of the body.
