Explanation:
Answer:
B
Explanation:
As there are lots of mitochondria within the diagram it is very unlikely that diffusion occurs. only active transport occurs. cells within the root do not look like the diagram shown thus the statement I and IV are true.
Air polution can cause things such as asthma, lung cancer, and many other things. air polution could also cause headaches, dizziness, nausea, and more.
Explanation:
If the concentration of molecules outside the cell is very high relative to the internal cell concentration, the rate of diffusion will also be high. If the internal and external concentrations are similar (low concentration gradient) the rate of diffusion will be low.
I believe that the answer is (A) , cause if their hetero then it could be a 50/50 chance so if its not (A) then it might be (D)
forgive me if i am wrong, have a nice day! :)
