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:
Explanation:
The parietal pleura represents a serous membrane b) lining the thoracic cavity.
The three main serous membranes in the body are the pleural, pericardial and peritoneal.
The pleura is a serous membrane that folds in two to create two layers in the pleural sac:
parietal pleura: outer layer that attaches to the chest wall and lines the thoracic cavity
visceral pleura: inner layer that covers each of the lungs individually
The peritoneal membrane lines the abdominal cavity.
The pericardial membrane covers the heart.
The visceral pleura covers the individual lungs
Answer:
Whole grains are grains that have their entire kernel (bran, endosperm and germ) intact therefore retaining valuable nutrients. Refined grains on the other hand are grains that have been milled and stripped off parts of their kernel therefore lowering their nutritional quality.
Explanation:
The main advantages of the oral route of drug administration over other routes are its non-invasiveness, patient compliance and convenience of drug administration.
<h3>What is drugs?</h3>
A drug is any chemical substance that, when eaten, induces a change in the physiology or psychology of an organism. Food and substances that give nutritional assistance are often distinguished from drugs. Drugs can be consumed through inhalation, injection, smoking, ingestion, absorption through a patch on the skin, suppository, or dissolving beneath the tongue.
A drug is a chemical substance with a recognized structure that, when delivered to a living creature, exerts a biological effect.
A pharmaceutical drug, often known as a medication or medicine, is a chemical compound that is used to treat, cure, prevent, or diagnose a disease, or to improve health.

Answer:
False.
Explanation:
Macula densa cells are present in the lining of the distal tubule. The cells are the thicker at the site where glomerulus and distal convoluted tubule touches each other.
Macula densa can sense the change in the concentration of sodium chloride ions in the distal convoluted tubule. The mcula densa cells cannot respond to the change in urea content of filtrate.
Thus, the answer is false.
