Answer 1

1A)  The quantity of water that we intake by any means needs to flushed out either by any form [ eg. urine or stools.... ] The amount of urine flshed out depends on how much water is intaken.Usually in summer when temperature is high we prespire alot. But in winter it is done in very low amount. So, inspite of taking high level water in summer we flush out water [ in the form of urine ] in low amounts....bt in winter even if we take less amount of water due to we don't prespire muh the water is flushed out in the form of urine. This is the reason why urination frequency is high in winter.  

2A ) The reason why doctors are prohibited to do sex determination through ultra sound scanning for pregnant women is there are two reasons..... a] some say it is harmful [b] some say as female infanticide is more in number sex determination shouldn't be done.  

3A ) We are advised not to talk while eating food because the food intead of entering into the food pipe it enters into the wind pipe which causes choking.  

4A ) The subcutaneous blood vessels bulges out on the other way from the heart when the hand is tied because the blood has to flow to all the body parts and when hand is tied the bood flow stops only in the hand but it flows all over the body. So, as the nerves have to pass the blood to all the other body parts the blood vessels bulges on the other side way from the heart when the hand is tied.

Answer 2

Urine is grouted more in summer because in summer - the temperature will be high and we usually drink more water in summer due to thirst. But whereas in the month of winter we preserve only little amount of water . So, inspite of taking high level water in summer we flush out water [ urine] in low amounts. But whereas in the month of winter it is opposite to it. So this is only reason why more urine is grouted in winter !!
