Hello. You forgot to mention that this question is about the poem "Icarus's Flight". it is necessary that you always provide all the necessary information for your question to be answered as you deserve.
Answer:
The poem states that Icarus did the right thing because he used his skills to try to achieve his desire, instead of just wondering if "would it have worked?"
Explanation:
In short, we can say that the poem states that Icarus did the right thing, because he allowed himself to try. He had a desire, which he knew was risky, but he preferred to use his skills, rather than just theorizing about what might or might not happen. Icarus had a desire and he challenged himself and went after it, instead of just whining and questioning.
The poem shows, in the eighteenth line, that even in the face of possible failure, Icarus' experience would allow him to know himself better, knowing his weaknesses and strengths.
Controls what substances can move in and out of the cell. it also protects the cell from its surroundings.
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
