How is kidney-function regulated when you drink excess amount of fruit juice?

Kidney functioning is regulated by hormonal feedback control mechanism. Explain this mechanism.

What is kidney transplantation ? When and how it can be done ?

The balanced equation for a reaction is given below 2x + 3y rarr 4l + m When 8 moles of x react with 15 moles of y, then (i) Which is the limiting reagent? (ii) Calculate the amount of products formed. (iii) Calculate the amount of excess reactant left at the end of the reaction.

How high most a body be lifted to gain an amount of P.E. equal to K.E. is when moving at speed 20ms^(-1). (The value of acceleration des to grity at a place is (9.83ms^(-2))

A fruit grower can use two types of fertilizer in his garden, brand P and brand Q. The amounts (in kg) of nitrogen, phosphoric acid, potash, and chlorine in a bag of each brand are given in the table. Tests indicate that the garden needs atleast 240 kg of phosphoric acid, atleast 270 kg of potash and atmost 310 kg of chlorine. If the grower wants to minimise the amount of nitrogen added to the garden, how many bags of each brand should be used? What is the minimum amount of nitrogen added in the garden?

When water is added to compound (A) of calcium, compound B is formed with a hissing sound and evolution of large amount of heat. When CO_2 , is passed into the solution, it turns milky due to formation of compound C. If excess CO_2 is passed into the solution, milkiness disappears due to the formation of compound (D). Identify the compounds A, B, C and D. Explain why the milkiness disappears in the last step.
