You made it in an earlier post; it was your answer to his 3rd question in the 1st sentence. Don't sweat it though, as it is a mistake that I also used to make often and always now have to think about before typing or writing out. And I'm pretty decent at English as well, so it's not like you're keeping poor company.

Oh, and you just owned him! :wink:

Oh there... I didn't think he would be that desperate to look back. :rolleyes:

Can we please keep this civil.

1. Explain the cohesion and tension theory in a plant
2.give me 3 main differences between veins and arteries
3.sum up the 4 stages of mitosis ( excluding interphase)
4. what does dna polymerase do

Of course. But, you've hardly avoided rudeness to others. :rolleyes:

i am stressed ok

That's understandable, but it doesn't excuse your previous behaviour in this thread. Although, I'm not one to hold grudges (or even have them), and so I'll draw a line under this.

Edit: I'm tempted to subscribe to TSR so I can hunt people down that -rep for ridiculous reasons. Go and get a life you tool!

Does a sunken stomata reduce WP gradient or diffusion gradient? or are they both applicable?

stomata sunk in pits which trap moist air, reducing evaporation.

Sunken stomata maintain humid air around the stomata and this reduces the water potential gradient.

Another one for 1) would be it is universal.
& For 4, I don't think its directly injected into species C, rather it is injected into a sample of albumin from species C, not sure if thats what you meant or not.
But good besides that. :smile:

1)What is cell differentiation?
2) Why is it more useful to compare base sequences of different species as opposed to the amino acid sequence?
3) Name the blood vessel:
- From the intestine to the liver
- Into the liver and out of the liver
- Into the kidney and out of the kidney
4) How are capillaries adapted for efficient gas exchange?

Can anyone share their notes on "Gaseous exchange in plants" please?

Function of cell walls:

- gives mechanical strength to a plant
- prevents a cell from bursting under pressure
- allows movement of water (apoplastic pathway) so contribute to the overall movement of water through a plant

Sorry I don't have any notes, I literally just use the textbook. The teachers haven't given us any sheets or anything worthwhile, I usually watch youtube videos to reinforce stuff when I can
