Answer:
A. 22.85 mL of oxygen
Explanation:
Data:
The total volume of Oxygen =500 mL.
Percentage of Oxygen inhaled= 20.94 %
Amount of Oxygen inhaled =20.94 /100 x500 ml
=104.7 ml
Percentage of Oxygen exhaled = 16.37 %
Amount of Oxygen inhaled =16.37 /100 x500 ml
=81.85 ml
Difference b/w amount of oxygen inhaled/exhaled= 104.7 ml-81.85 ml
=22.85 ml
Therefore, Option A is correct option.
Hope it help!
Maintaining Homeostasis. The process in which organ systems work to maintain a stable internal environment is called homeostasis. ... Endocrine system: A high concentration of sugar in the blood triggers secretion of insulin by an endocrine gland called the pancreas.
The normal blood glucose level (tested while fasting) for non-diabetics, should be between 3.9 and 5.5 mmol/L (70 to 100 mg/dL). ...
Blood sugar levels for those without diabetes and who are not fasting should be below 6.9 mmol/L (125 mg/dL).
There are lots of different hormones in the human body that serve lots of different functions, but some are used to maintain homeostasis of various physiological parameters, like blood glucose levels. Blood glucose levels are regulated by two opposing hormones: insulin and glucagon.

The first step in describing and analyzing most phenomena in physics involves the careful drawing of a free-body diagram. Free-body diagrams have been used in examples throughout this chapter. Remember that a free-body diagram must only include the external forces acting on the body of interest. Once we have drawn an accurate free-body diagram, we can apply Newton’s first law if the body is in equilibrium (balanced forces; that is, Fnet=0" role="presentation" style="font-family: proxima-nova, sans-serif; -webkit-font-smoothing: subpixel-antialiased; padding: 1px 0px; margin: 0px; font-size: 17.44px; vertical-align: baseline; background: rgb(255, 255, 255); border: 0px; outline: 0px; display: inline-block; line-height: 0; text-indent: 0px; text-align: left; text-transform: none; font-style: normal; font-weight: 400; letter-spacing: normal; overflow-wrap: normal; word-spacing: 0px; white-space: nowrap; float: none; direction: ltr; max-width: none; max-height: none; min-width: 0px; min-height: 0px; color: rgb(55, 61, 63); font-variant-ligatures: normal; font-variant-caps: normal; orphans: 1; widows: 2; -webkit-text-stroke-width: 0px; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial; position: relative;">Fnet=0Fnet=0) or Newton’s second law if the body is accelerating (unbalanced force; that is, Fnet≠0" role="presentation" style="font-family: proxima-nova, sans-serif; -webkit-font-smoothing: subpixel-antialiased; padding: 1px 0px; margin: 0px; font-size: 17.44px; vertical-align: baseline; background: rgb(255, 255, 255); border: 0px; outline: 0px; display: inline-block; line-height: 0; text-indent: 0px; text-align: left; text-transform: none; font-style: normal; font-weight: 400; letter-spacing: normal; overflow-wrap: normal; word-spacing: 0px; white-space: nowrap; float: none; direction: ltr; max-width: none; max-height: none; min-width: 0px; min-height: 0px; color: rgb(55, 61, 63); font-variant-ligatures: normal; font-variant-caps: normal; orphans: 1; widows: 2; -webkit-text-stroke-width: 0px; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial; position: relative;">Fnet≠0Fnet≠0).
The human body has over 700 enzymes - each, specific to one particular chemical reaction (within the body.) So, I think that the body will have different enzymes to break down proteins within the body and another, different, protein to build proteins in the blood. Hope this helps.
