Bio paper 31

[Lulu Kim]

it was good,what did you write for the question in which they asked about mammals living cold water?

Explain vasoconstriction

 

[1D123]

i wrote that too

 

[Starkiller96]

Explain vasoconstriction

Narrowing of 'Arterioles' not capillaries, to prevent heat loss

 

[Hamzeh S]

Explain vasoconstriction

i wrote narrowing of blood vessel and relaxation of hair errector muscle to decrease heat loss and homeostasis , and that they have a system the regulates temperature in the body is it right ? :S

i just need to ask dat is it true dat there wont b any threshold dz year??

thanks in advance

There will be its just rumors spread every year

i wanted to ask dat on da last page of da ppr...variant 1...was da frst anser similar to da 1 in wich dey asked about wt will be the effect on the atmosphere?>

i wrote the effect on the other page and on the downside i wrote bird lost habitat and floods and soil erroision i wrote co2 and o2 ..etc but erased it after i wrote it in the other question

 

[pk1947]

ok thanks

 

[pk1947]

also i wanted to ask dat on da 1st page..was j repeated 2ice...or not??

Explain vasoconstriction

guys don't you think the answer was that reptildes are cool-blooded animals and mammal warm-blooded !?

 

[hEbBoOo]

Hay please guys how are you?! I wonna ask about the thin-threads of the fungi were it was rizoid or haypae!?!?

 

[hEbBoOo]

How was it guys?

AMEEEEEEN! Hope mine too!

 

[hEbBoOo]

it was good,what did you write for the question in which they asked about mammals living cold water?

I wrote that the mammal are endothermic and they have the tendency to regain there body heat and activity by using aerobic respiration!

 

[hEbBoOo]

guys don't you think the answer was that reptildes are cool-blooded animals and mammal warm-blooded !?

YEAH!!

 

[hEbBoOo]

No, if you remember the question correctly, it said ''Water reabsorbed''
That occurs in the Large intestine=Colon
So you're Wrong.

it also said that MOST water is reabsorbed that means you are right about the large intestine and i did it!! AL 7amdullah!!!

 

[hEbBoOo]

how much do you think A* will be??
I really fucked up in last 2 pages(8 marks are wrong)+like 1 mark in each page
I have studied too much Biology this year & sacrificed with other subject for it , I hope I don,t get anything but A*

What were the answers for female reproductive system btw if any one still remember?
1-y then x
2-umbilical chord,tied & cut after birth
3-I wrote the uptake of oxygen , glucose , amino acids , fat , iron ,water from mother to fetus
& diffusion of co2 from fetus to mother
are those right especially no3 ??

yeah and i wrote it like that too in number 3 btw!! high five bro!!
but i dont actually remember 1 & 2!!!

 

[0Louis0]

it also said that MOST water is reabsorbed that means you are right about the large intestine and i did it!! AL 7amdullah!!!

actually large intestine reabsorbs 0.3-0.5L while small one 5-10L of water so "most" should be indicating small intestine but im not sure

 

[TheBaller23]

i wrote narrowing of blood vessel and relaxation of hair errector muscle to decrease heat loss and homeostasis , and that they have a system the regulates temperature in the body is it right ? :S

not relaxaton, its contraction!! think practically, when your cold does ur hair stay down or stand up and get goosebumps?

Quote from my book: "Large Intestine - (wider than the small intestine) The colon is part of the large intestine. It reabsorbs water from gut contents; also absorbs some vitamins and minerals"
