How was it guys?

 

[1D123]

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

wasn't it all about the homeostasis of thermoregulation...fur,fat e.t.c

 

[1D123]

i wrote about the homeostasis thing aswell but im not sure about my answer.

am pretty sure its rite....
ch33rs

 

[bm95]

yeah, same. i wrote about thermoregulation and all that... i think i even wrote about vasoconstriction but I'm not sure if thats correct. oh and btw, what did you guys write for the question on the last page when it asked 2 reasons why the plant yields decreased?

 

[K Raja]

i)loss of nutrients....erosion
ii)no/less water held/absorbed by plant

 

[1D123]

i wrote soil erosion and the soil will be lose so major crops wont grow.

 

[1D123]

are we allowed to discuss the questions?its just been 2 hrs.

yeah we had to write that they r warm blooded and the ways by which they achieve a warm internal conditions and in the end I wrote that the enzyme get the best temp. to work so the mammals can maintain the metabolic activities and can move

Also wat U wrote for the graph question last part...which says how u know there r two enzymes??

You can write:
1. Fur maintains the internal temperature.
2. Vasoconstriction
3. Regular movements in water that releases energy by aerobic respiration.

I didnt write pt. 3 but i wrote abt shivering will i get the marks? P.S it was for 4 marks rt?

There were 2 optimum PH for the two graphs, I wrote that :/

yes sure u r ryt!

Shivering. I don't mammals shiver in water. You can write shivering, if you stated that muscles contract and move their bodies frequently energy is released that warms the body. I don't think marks will be lost.

 

[Yousif Mukkhtar]

For the 2 enzymes I wrote the enzyme at ph 5 works best after 12 days and the one at ph8 works after 15 days the best.

Contraction dammit! I forgot to write that but I wrote abt the energy released by shiverring

Of course that is right. Energy is the most important thing.

 

[1D123]

for the ph 5 it was clear for ph8 i wrote that it doesn't gget denatured and works best at ph8 where the ph 5 one works best in acidic conditions
