Answer:

Digestion is the breakdown of large insoluble food molecules into small water-soluble food molecules so that they can be absorbed into the watery blood plasma. In certain organisms, these smaller substances are absorbed through the small intestine into the blood stream.

Explanation:

Digestion works by moving food through the GI tract. Digestion begins in the mouth with chewing and ends in the small intestine. As food passes through the GI tract, it mixes with digestive juices, causing large molecules of food to break down into smaller molecules. The body then absorbs these smaller molecules through the walls of the small intestine into the bloodstream, which delivers them to the rest of the body. Waste products of digestion pass through the large intestine and out of the body as a solid matter called stool.

After age 50, bone breakdown (resorption) outpaces bone formation and bone loss often accelerates, particularly at the time of menopause.

What is Osteoporosis ?

Osteoporosis causes bones to become weak and brittle — so brittle that a fall or even mild stresses such as bending over or coughing can cause a fracture. Osteoporosis-related fractures most commonly occur in the hip, wrist or spine. Bone is living tissue that is constantly being broken down and replaced.

Osteoporosis is a disorder where your bones become brittle, fragile, and easily breakable as you age because certain minerals begin to leach out of them. Because estrogen, which helps keep bones strong, is lost during menopause, women over 50 are particularly at risk for osteoporosis.

Vlad1618 [11]

Answer:

The correct option is <em>B. Cholesterol is non-polar.</em>

Explanation:

Cholesterol is a non- polar substance and due to this property it is an active part of the cell membrane. Cholesterol molecules help to maintain the stability of a cell. When the temperatures are high, cholesterol stops the cell membrane from crystallization. When the temperatures are low, cholesterol reduces the packaging of molecules of phospholipids. As a result, fluid phase is archived by the cell membrane.
