Question 3, the answer is Zygote
Sorry that's the only one I can answer for sure right now.
Atherosclerosis and the obvious danger of free floating cholesterol in the blood that can circulate and deposit anywhere, even in the arteries/veins while flowing which can also cause a blockage of arteries/veins and cause an embolism. Also fatty deposits in the cell's membrane that can make it more fluid than it should be causing the cell to lose its rigid membrane structure or even making it more rigid sometimes depending on the environment.
When the concentration o molecules inside a cell is different form the concentration of molecules outside a cell, we can either call it hypertonic or a hypotonic solution, and the difference between the two concentrations is called a concentration gradient.
Hypertonic - name given to a solution that has a bigger concentration than the concentration in a cell.
Hypotonic - name give nto a solution that has a smaller concentration than the concentration in a cell.
Hope it helped,
