It's common sense. More urination is a result of taking more water.

You have three Drinks.

And out of those drinks, Drink A results in more urine. That implies it has a higher water content, leading to more EXCESS WATER being in the urine.

No.
More urination is the result of the less reabsorption of water by the kidneys. When you drink more water and it exceeds your body requirement then more water is allowed to pass out, hence urine dilutes. But here all three are taking equal amount of juice but even then one urinates more other less so what does this show? When drink A is taken kidneys are unable to absorb water much.

A bhai.

Its A

What does that prostrate glands wala sawal mean? :v

It enlarges. It presses on urethra. As a result less urine is secreted.

 

[Abdul Hanan]

Okay

bro i know you cleared every thing.
according to me "people " are taking the drinks as "water or somethin" the drinks contain other stuff aswell!!!! like minerals etc...
we can take it this way... drink A is water and drink C "apple juice"
when you are hot and need to cool down you will for sure take water!!!!!
so, C (juice) should be avoided

 

[Dark Destination]

You dont know that lol.
You dont know which had more water, which was coffee, which was water, which was tea.
All we knew we the total volume of per liquid and the amount urinated.

So you're saying that Drink C had more water content.

Exactly. *Sigh*

At least someone understands.

no!. read this problem on google..
the prostate gland applies pressure on tube that carries urine which causes pain in urinating.

If they are unable to absorb, that just shows it had more water.

You've typed? I typed a whole essay -.- No one understands. I've given up.

If the prostate grows too large, it may constrict the urethra and impede the flow of urine, making urination difficult and painful and, in extreme cases, completely impossible.

Taken from Wiki. It does decrease urine aswell. Yours is also correct though.

Let's wait for the Mark Scheme.

In P1,whats for the question about syphilis? and what about the discontinuous changes...is it large?

 

[funky brat]

okay so it was A for sure. Ziada water loss, is se aik aur masla bhi ho sakta hai, blood mai water potential kam hoga, cells se paani nikal aye ga, cells would be damaged ke sahi nahi ho sakte.

I've told this already. No one listens.
