Active transport means that work is being applied to help move the molecule. I’m pretty sure the answer is B: low to high concentration.
Long ears have to be dominant:
If this IS true then these would be your 'parents':
L = long ears
l = curly ears
LL x ll
If you cross the homozygous recessive curly eared rabbit (ll) with homozygous dominant long eared rabbit (LL) you would get 100% Ll - all would look long eared.
The cell would die. This is because mitochondria are essential for making energy that the cell can use, if the mitochondria stopped working this energy would not longer be available to the cell. If the cell does not have energy, it cannot perform vital functions like respiration.
The question is referring to primary succession, which begins with the colonization of living organisms in an area that hasn't had any living organisms before.
This kind of succession begins with microorganisms, and plants such as lichens and mosses.
Given that a rock outcrop is a terrestrial environment, lichens (C) are most likely to be the firsts organisms.
