a) The urine gets concentrated by reabsorption of water.
b) Vasopressin is secreted only when concentrated urine is to be passed out

Concentration of urine depends upon

I am a hormone. I help in th e formation of concentrated urine. Who am I?

The person A urinated less concentrated urine. The person B urinated high concentrated urine. The hormone controlling this…………….. a) insulin b) vasopressin c) Thyroxine d) Adrenalin

Name the hormone that helps in the formation of concentrated urine.

A reaction is first order in A and second order in B. i) Write the differential rate equation ii) How is the rate affected on increasing the concentrations of B there times ? iii) How is the rate effected when the concentrations of both A and B are doubled ?

Silver metal is extracted from Ag_(2) S by cyanide process. The one is concentrated through froth floation process. The concentrated ore is the leached and solution is r ed with reducing agents to get spongy silver which then purified by fusion with an oxidant followed by electrolysis. Leaching of Ag_(2)S is carried out by heating it with a dilute solution of

Consider the following four statements (i)-(iv) about certain desert animals such as kangaroo rat. i) They have dark colour and high rate of reproduction and excrete solid urine ii) They do not drink water, breathe at a slow rate to conserve water and have their body covered with thick hairs iii) They feed on dry seeds and do not required drinking water iv)They excrete very concentrated urine and do not use water to regulate body temperature. Out of these four, which two are correct :

For a reaction A+Bto productss the rate of reactions is increased by 8 times when the concentration af A and B are doubled. The rate of reaction in doubled when the concentration of A alone is doubled. Then
