Question 8

When they mention changes in temperature what do you have to do aswell?

Answer 8

Mention high temoertaure and low temoertaure too and what happens for both

And here you mention went straight away to denaturing when actually a good amount of q was why doing it wa goof
Remember in ensymes increase temp is good because more likely enzyme substrate compels formed, but too much causes breaking id bonds in tertiary and so change to 3d shape, change to active site, can no longer fit or cause it to change shape to fit, so cantcalayse

But go too les and rate of reavtion just decreases, reversible but decreases

And lrocessof it happening, first they collide successfully , then enzyme substrate made, revstjon happend enzyme product made then it splits

Question 9

Fraud 6 markers askmfor dimialrlites and difference what should you do

Then the membrwne hasn’t disintegrated but no nucleolus ANother tell
But what you thought - the fact that they aren’t arranged in the middle, or at poles or as separate cells suggests it has ti be prophase

Question 12

Okay remember dknt descibre bivslsnrtd for metaphase, whole point is that it’s random assortment

Answer 14

Xeroyohytes have thicker kigninfied walls? For xylem

And hdrlhote thin but that makes sense because most of plant just supoorted by water so structure don’t have ti be that string

I think they mean more lignin less water loss but idk

Question 15

Xylem and blöken similarity

Answer 15

Both msde up walls joined end to end and have lack of contented

Question 16

• animal has smooth muscle too aswell as elastic and also ciklated m insect don’t

Question 18

Alveoli full adaptations what would you say

Answer 18

Not only Sa, distance, conc grsdient vent and blood supply

Not only surfactant and moist

But also ELASTIC FIBRES and how that helps

And also warm temperatures INCREASE RATE OF DIFFUSION

Question 19

For suggest wuestions lit suggest something to every little thing you can think of

If it says use the data USE IT

Question 20

Reasons why species decline ?

Answer 20

Less amount of food types less, more pesticide used here , likely to be a monoculture which mead to less variety of food

Or because no attempt o save like wildlife reserves or just management causes less habitat and thus less species

Question 21
