Drink A was the answer. I'm sure about it.

 

[funky brat]

The total volume for each Drink was 1.5 dm^3.
You take 1.5 dm^3 of A. You lose 90% of it.
You take 1.5 dm^3 of B. You lose 80% of it.
You take 1.5 dm^3 of C. You lose 65-70% of it.
Clearly Drink C loses less water so why would you avoid it. I dont care about what the doctors say. When the graph supports that A actually loses most of itself in urine, it's not doing the body any good. So it's avoided.

The person is already losing water through sweating, he would simply be dehydrated if he takes Drink A that causes a lot of urination so A was the answer, simple.

what about the spinner? i was stuck in that question

 

[funky brat]

But why should Drink A be avoided?
Isn't it providing sufficient water to counter the hot weather?

Would you rather drink C, with low water content, and die of dehydration and excessive sweating? o.o

God, who said the graphs were about water content? -.-

 

[funky brat]

You're saying that Out of 1.5 dm^3, most of Drink A was lost in Urine. So it's not providing any sufficient water.
That Volume that is lost in the urine, actually, is the WATER.

Drink C had so less water (it was full of other stuff - that wasn't water), that a small amount of urine was produced. That isn't sufficient for a hot day.

No, no no.
Drink A causes more urination means that it reduces the ability of the kidneys to reabsorb water to the maximum infact allowa more dilute urine to be produced retaining less water.

Easy.
40, 20 in table.
Spinners were Parent organism, Spinning was crossing over and Letter were Alleles.
And for last part we had to write parent's alleles on the spinner then spin them.

Exactly but I wrote parent's first and then changed it to geneticists.

What is the person losing 90% of Drink A? Because it has a high water content.

Drink C loses 65-70%, because the stuff that isn't lost, isn't even water. It is a drink that has low water content (as it produces less volume of water in urine)..

More Urine = More Water in the body = Drink A.

Less Urine = Less Water in the body = Drink C.

So such a drink should be avoided.

Just image, Drink A is Pure water. Drink C is Coffee.

If you take Drink A, a greater volume of urine would be there, but that is more suitable for hot weather. It provides so much water, that even after being absorbed from large intestine, their is excess water in the blood, that is lost through the reduced secretion of ADH.

I guess their is no use arguing. Just wait for the marking scheme.

can the spinning be "fertilisation" ?

You say that more urine = more water in the body but what use is that water when all of it is gone lol?

Parents? I wrote breeders.

Um most of my friends wrote parent organism or parents

God, we must wait.
Why are you even talking in terms of water content, how can you even tell this by looking at the graphs for urination?

 

[Fate0]

Alright Geniuses, get off that awful question, and come to P1. WHAT WAS THE ANSWER OF THE VEINS QUESTION WITH A VALVE AND 2 DIFFERENT DIRECTIONSSSSSSSSSSSSS!

Heart,Brain. Was from PP's.

 

[Dark Destination]

You say that more urine = more water in the body but what use is that water when all of it is gone lol?

But with Drink C, even after losing 65-70% of it, who said that WATER was left behind?
Maybe all the water it had was excreted out.

Do you at least agree that Drink A had more water content?

A bhai.

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.

 

[funky brat]

Okay, let's get over this, urination question though I'm still as convinced that it's A.

Exam in 3 hours, anyone may briefly explain the stages of nitrogen cycle? Thanks.

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.
