<span>Phosphorous cycle. </span> It differs from the other major biogeochemical cycles in that it does not include a gas phase
<span>The cell membrane folds around the molecule.</span>
Answer:Phosphorylation cascades are similar to a row of dominoes falling down, instead of one domino knocking down the next, a phosphate being added activates the message. In this way, a series of different _(phosphate group) are each _(added ) after another. Inactive protein kinase 1 gets a __(phosphate group_)___ added and now it is active protein kinase 1. Active protein kinase 1 transfers a (phosphate group) and now inactive protein kinase 2 is now ___(active)_____. This continues until the desired (protein ) is activated to cause a cellular response.
Explanation:
I believe that the answer is D. If something has evolved, it can not interbreed with its old species. I think this is right!
