Answer: The Parathyroid gland
Explanation:
The Parathyroid gland secretes "Parathormone", an hormone that exerts
- direct influence on the bone by INCREASING the release of bone calcium ion (Ca2+) into the blood
- affects the kidney by stimulating the renal tubules to eliminate EXCESS calcium in the urine.
Thus, the calcium balance of the body depends on the secretion of the Parathyroid gland
Answer:
a.) It causes prolonged activation of adenylyl cyclase which leads to increased levels of Cyclic adenosine monophosphate(cAMP).
b.) In the intestinal epithelial cells, the cAMP binds to the apical chloride channels and allows it to open leading to osmotic permeability of water across the cell into the lumen of the intestine which is excreted through the faeces.
C.) Cholera can effectively be treated through the use of antibiotics and intravenous fluid replacement therapy.
Explanation:
Vibrio cholerae is a gram negative rigid curved bacillus that are actively ( vigorously) motion by a polar flagellation. The name vibrio is derived from the characteristic vibration movement of the organism when viewed under a microscope. This bacteria is capable of producing toxins called cholera toxin, which it uses as a virulent factor. It is responsible for the characteristic symptoms of cholera: extensive loss of body water and NaCl through continuous, debilitating diarrhea.
Cyclic adenosine monophosphate(cAMP) which is called a second messenger because it is not a hormone that can directly institute an intracellular change, instead, it serves as a second messenger to cause an effect.In the intestinal epithelial cells, the cAMP binds to the apical chloride channels and allows it to open leading to osmotic permeability of water across the cell into the lumen of the intestine which is excreted through the faeces.
In the effect of cholera toxin on the cAMP in the intestinal cells, Cholera toxin increases the fluid loss. The binding of the toxin to the intestinal cells causes a large increase in the level of cAMP in the cells by inhibiting the conversion of GTP bound to Ga to GDP. So adenyl cyclase is not turned off and diarrhea results.
The possible treatment is through the use of antibiotics and intravenous fluid replacement therapy. Prompt and adequate replacement of lost fluid and electrolyte through oral administration and supplemented with intravenous administration of fluids highly suggested for treatment of cholera. Antibiotics is equally used for treatment only when the cholera strain has been confirmed sensitive to it through culture.
It leads to the formation of water and polymers
Answer:
the correct awnser is B
Explanation:
Sorry i cant explain i gtg but hope this helps
Answer: It releases oxygen and heat. The answer is C
Stored inside the match head is another chemical called “potassium chlorate”. When it gets hot, it releases a lot of extra oxygen and heat. This makes the match head burn quickly and strongly. When you put it all together the heat, the fuel, and the oxygen you get a flame. Matter does not go when something is set on fire. Matter is always the same. Burning is a chemical process. The flames are caused as a result of a fuel undergoing combustion (burning). (CC BY-SA 2.5; Einar Helland Berger for fire and Walter Siegmund for ash).
