Statement D. Is not true.
Renal autoregulation is the ability of the kidneys to maintain a relatively constant GFR or glomerulofiltration rate despite fluctuating blood pressure. Autoregulation is a remarkable property of multiunit smooth muscles of small arteries and arterioles to respond to changes in internal and external pressure. The blood vessels in the human body react by contracting whenever the blood pressure is elevated and by expanding when the blood pressure is reduced. On the other hand, if there is an elevation or reduction of the external interstitial pressure, it results in dilation and contraction, respectively. The lowest autoregulating pressure is about 60 mmHg. By a further reduction in perfusion pressure, RBF is sharply reduced.
The X-gal medium is suitable for detection of gene regulation of the lack operon gene. The media turns from white to blue in the presence of beta-galactosidase, a gene product of lacZ. Beta-galactosidase cleaves lactose into galactose and glucose. Utilisation of lactose as an energy source by Escherichia occurs when there shortage of glucose in the environment.

Have a great day :)
If the patient weight is 250 lb and the doses are 0.8mg/kg/hour for 12 hours, then the total amount of theophylline needed would be:
250lb * 0.453592kg/lb* 0.8mg/kg/hr * 12hr= <span>1088.6208mg
If the solution contains 800mg of </span>theophylline for 100ml volume, then the volume needed would be: 1088.62 mg / (800mg/100ml)= 136.07ml
