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.
Answer:

The body's use of signal transduction is to ultimately result in a cellular function.
Answer:
a
a process that selects variations to help with survi al and that spreads the variation to more offspring
Explanation:
the weak don't survive the strong thrive
It's similar in the sense that when an ecosystem is challenged above its initial capacity, so can roads be challenged over their carrying capacity. When this happens, an ecosystem/roads "break down" start worsening the function they were supposed to do and in general become worse and worse.
Active transport uses energy passive transport does not..... active transport moves from lower to higher concentration and vice versa in passive transport.... both use carrier proteins....
