1. Is artery an organ or an tissue?
2. What is the process by which carbon dioxide is removed from living organisms?
3. Which process is responsible for returning water vapour to the air?
4. How is the growth of a population where there are no limiting factor?
Thx so much.

1)an artery is a tissue
2)respiration
3)the water vapor comes as a product of respiration
4)the curve keeps going higher, the gradient doesnt go to 0, population keeps increasing
Hope it helped

Thanks a lot for your help! I am a bit confused about the question 1 and 2 since the answer on marking scheme: 1)an organ,2)excretion.....
Probably the ms is wrong?

Assalamoalaikum wr wb!
An artery is an organ made up of many different tissues...
And the removal of carbon dioxide is excretion..respiration doesn't "remove" carbon dioxide..it gives it out, instead!

So the ms is right..
