Answer:
Hi there!
Your answer is:
It is very important for the cell membrane to be <em>semi-permeable</em> because the ability to pick and choose what comes in and out of the cell keeps the cell safe! The membrane can choose to block out nasty germs and can also choose to get rid of internal waste.
An example of when this is important is in this scenario:
Let's say the cells are in a really salty solution. Naturally, salt will want to pull the water out of the cell. If the membrane <u>wasn't</u><u> </u> semi permeable, the water would listen to the salt and leave the cell. This would cause cell death. <u>BECAU</u><u>SE</u> the membrane is semi permeable, they can choose <em>not</em> to give the salt any water, keeping them alive
Hope this helps

The answer to this question would be: <span>a. optic chiasm
The optic nerve will be crossed in optic chiasm. Only a part of the optic nerve is crossing the midline. So, if there is a damage in the nerve after crossing, the visual loss will not only appear in one eye but half of both eye. Damage in right visual cortex will cause the left and right eye losing their half (left part) of their visual field.</span>
