Answer:
The correct answer is option (C) "After splitting ATP, a protein changes shape to pump ions across a membrane".
Explanation:
Adenosine triphosphate (ATP) is an organic chemical molecule considered the "molecular unit of currency" of intracellular energy transfer, for the high level of energy that is released when ATP is breakdown into adenosine diphosphate (ADP). ATP provides energy to drive many processes in living cells. One example of how the chemical potential energy of this molecule is turned into work is that after splitting ATP, a protein changes shape to pump ions across a membrane. The energy of the splitting of ATP into ADP will provide energy for the protein being able to change shape, resulting in pumping ions across a membrane.
Cancer cells are cells that basically bypass any sort of regulatory processes in the cell cycle (and mitosis - the splitting of the cell). This leads to uncontrollable cell growth/duplication which hence leads to more and more cancerous cells. Cancer itself is so hard to cure for a couple of different reasons. If the cells are in the form of a benign tumor, that is a tumor that does not spread from its original infected tissue, it should be "easy" to remove with surgery. However, if it metastasizes, or spreads into surrounding tissues through the lymph or blood systems, then it becomes even harder to remove because of its far reach and complex structure. Also, cancer cells can be simply described as normal body cells that have gone rogue. That being said, things such as antibiotics, that are designed to get rid of foreign bodies, cannot get rid of cancerous cells without getting rid of most of your regular body cells as well simply because they cannot tell the difference.

Answer:
Which generations saw a population altering incident? Use your imagination to invent apossible environmental incident that could have caused this shift in populations. The white bears saw a population altering incident because in generation 6 the number wentdown pretty unexpectedly.
