Biologists have been able to produce mice that lack functioning genes for aquaporins. how would the urine of these mice compare to that of mice with normal aquaporins? a) lower volume and lower osmolarity b) higher volume and higher osmolarity c) higher volume and lower osmolarity d) lower volume and higher osmolarity

The answer is C.

Explanation:

Aquaporins are proteins that are located in cell membrane which transports water between intracellular and extracellular environment. Experimental evidence shows mice lacking aquaporins consumes ten times more fluid and secretes urine with lower osmolarity, which is called polyuria.

The correct answer is 1500 milligrams.
The DASH diet is a diet and lifestyle plan which helps prevent or treat high blood pressure. DASH stands for Dietary Approaches to Stop Hypertension. A DASH diet's main points are to reduce the intake of sodium and increase the intake of important nutrients, such as potassium, calcium and magnesium. This diet has shown to successfully reduce blood pressure even in the first two weeks of implementing it. 
According to the standard DASH diet, a person should not consume more than 2300 mg of sodium daily. If you are on a low-sodium DASH diet, you can only consume up to 1500 mg of sodium daily.
