Answer:
An acid is a chemical that dissociates releasing free hydrogen ions.
Explanation:
The chemical equation for an acid is HA⇄A- + H+
The free hydrogen ion (H+) is what gives the substance the quality of acid.
Answer:
c. The function of glucagon is to increase blood glucose concentration. All mentioned processes are consistent with this function.
Explanation:
Glucagon is the enzymes synthesized and released by alpha cells of endocrine pancreas in association with food. Glucagon causes an increase in blood glucose levels and it does so by :
1) Inhibiting the process of glycolysis so that the glucose is used less.
2) Stimulating the breakdown of glycogen to increase the glucose concentration in the blood.
3) Stimulating gluconeogenesis in the liver thus increasing the synthesis of glucose in liver.
All these processes directly increase the level (concentration) of glucose in blood.
Hence option C) The function of glucagon is to increase blood glucose concentration. All mentioned processes are consistent with this function is true
Answer:
Blood pressure is the pressure of circulating blood against the walls of blood vessels. Most of this pressure results from the heart pumping blood through the circulatory system. When used without qualification, the term "blood pressure" refers to the pressure in the large arteries.
Explanation:
Blood pressure is measured in units of millimeters of mercury (mmHg). The readings are always given in pairs, with the upper (systolic) value first, followed by the lower (diastolic) value. diastolic blood pressure of 88 mmHg. When your heart beats, it squeezes and pushes blood through your arteries to the rest of your body. This force creates pressure on those blood vessels, and that's your systolic blood pressure. A normal systolic pressure is below 120. A reading of 140 or more means you have high blood pressure.
