The best answer to the question: The preferential use of phosphatidylinositol and phosphatidylethanolamine in the cytoplasmic leaflet of membranes leads to increased:___ would be, D: All of the answers are correct.
Explanation:
There is still a lot of debate among scientists as to the exact way in which phospholipids are distributed between the two leaflets of a cell´s plasma membrane, but what they do know is that there are four kinds, and that phosphatidylinositol (a sterol) and phosphatidylethanolamine appear most commonly on the cytosolic, or cytoplasmic side of the membrane. They also believe that it is this particular arrangement which allows the cytoplasmic side of the membrane to be slightly negatively charged and this role will play a major part in a membrane´s ability to generate an action potential. Also, it is known that these negatively charged ends of the bilayer will allow certain proteins, positively charged ones, to be inserted, and connected to it, to become transporters, or mediators in action potentials and normal activities of cells. Finally, since fatty acids and cholesterol are associated with phospholipids, but have a tendency to be attracted to these particular two types, they tend to give the overall structure fluidity, but also permit the inner leaflet to assume its particular circular shape around the cytoplasm. This is why the answer is D.

Explanation:
Hope this helps :)
Mitosis is closely controlled by the genes inside every cell. Sometimes this control can go wrong.
If that happens in just a single cell, it can replicate itself to make new cells that are also out of control. These are cancer cells.
They continue to replicate rapidly without the control systems that normal cells have.
Cancer cells will form lumps, or tumours, that damage the surrounding tissues. Sometimes, cancer cells break off from the original tumour and spread in the blood to other parts of the body.
When a tumour spreads to another part of the body it is said to have metastasised.
They continue to replicate and make more tumours. These are called secondary tumours.
So the answer should be A.) mitosis
A and I’m pretty sure it’s D as well :)
