Answer:
The correct option is BLOOD CALCIUM LEVEL.
Explanation:
The options attached to this question are given below:
A. Filtration membrane integrity
B. Systemic blood pressure
C. Blood calcium level
D. Renal artery/arteriole diameters
Kidney is an excretory organ, which functions by filtering waste products out of the blood. The rate at which the kidneys filter the blood depend on some factors; such factors include: water intake, systemic blood pressure, vasoconstriction, dehydration, filtration membrane integrity etc.
Blood calcium level does not have any effect on the rate at which the kidneys filter the blood.
Answer:
There are a number of mechanisms through which a bacterial cell might become resistant to a specific antibody.
- Some bacteria might posses a cell membrane which wouldn't allow the transfer of antibiotics into the cell of the bacteria. Some bacterial cells might not have the target sites on which the antibiotics attack. A bacterial cell that would be non-resistant wouldn't block the entry of the drug or it might not lack the site where the drug has to function.
- Some resistant bacteria might produce enzymes that would inactivate the activity of the antibiotics. This enzyme machinery would lack in a non-resistant strain. The resistant bacteria might have undergone mutations over a period of time to evolve a machinery for antibiotic resistance.
