Answer:
The correct answer is D.
Explanation:
Bordetella pertussis is a gram-negative coccobacillus that causes a disease called whooping cough.
The bacterium infests the patients by colonizing lung epithelial cells. To do so, it requires adhesins, called filamentous haemagglutinin, fimbriae and pertactin. Once the bacterium is attached to the lung epithelial cells, it produces a cytotoxin that prevents their cilia from moving.
Another virulent factor from B. pertussis is the pertussis toxin, which alters host immune system through the inhibition of phagocytes response to it.
The most important prerequisite for assessing the quality of health care delivery system is to collect the medical records of the patients admitted and discharged from the hospital.

Answer:
The chemical receptors of cells have been defined as molecular structures to which other molecules considered as chemical messengers (neurotransmitters, hormones and other neuroactive molecules) specifically bind.
Chemical receptors can be located on the plasma membrane into which they insert by crossing it. Membrane domains have been defined for them and also on both sides of the membrane. The one on the external side corresponds to the binding site for messengers that come from other cells, a situation that defines the so-called heteroreceptors. If messengers coming from the cell itself join that site, the so-called autoreceptors are defined.
But chemical receptors can also be located inside cells. They are intracellular receptors and are found in the cytoplasm or in the nucleus. Messages act on them, which due to their chemical nature can cross the plasma membrane, such as steroidal hormones, thyroid hormones and neurosteroids

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
