B and D!! I did this in school. Brainliest? Have a good day :)
Answer:
Smooth Muscle
Explanation:
In the digestive tract it's called the muscularis mucosa.
Answer:
The correct answer will be option-A.
Explanation:
ADH or anti-diuretic hormone is a chemical messenger produced by the hypothalamus in response to the water level in the blood, maintain blood pressure.
ADH is released in response to the osmolarity of the blood that is a low amount of water which is perceived by the osmorecpetors in neurons. The low level of water leads to the production of ADH from neurons which binds to the ADH receptors in the collecting tubules of the kidneys.
They allow insertion of aquaporins-2 in the membrane which allow re-absorption of the water to maintain the water level of the body.
Thus, option-A is the correct answer.
Answer:
The cell interior would experience higher than normal Na+ concentrations and lower than normal K+ concentrations.
Explanation:
Na+/K+ ATPase exists in two forms: Its phosphorylated form has a high affinity for K+ and low affinity for Na+. ATP hydrolysis and phosphorylation of the Na+/K+ pump favor the release of Na+ outside the cell and binding of K+ ions from the outside of the cell. Dephosphorylation of the pump increases its affinity for Na+ and reduces that for K+ ions resulting in the release of K+ ions inside the cells and binding to the Na+ from the cells.
The presence of ATP analog would not allow the pump to obtain its phosphorylated form. Therefore, Na+ ions would not be released outside the cells. This would increase the Na+ concentration inside the cell above the normal. Similarly, the pump would not be able to pick the K+ from the outside of the cell resulting in reduced cellular K+ concentration below the normal range.
