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.

According to this theory of chemical evolution, <u>synthesis of organic molecules </u>would need to occur first for life to evolve.
Explanation:
This theory (of Abiogenesis) is corroborated by the <u>Miller –Urey experiment </u>that attempts to replicate the early conditions of the earth. It is believed that organic molecules were created spontaneously through chemical reactions spurred by bolts of lightning resulting in the creation of simple organic molecules like lysine amino acid. These organic molecules made the oceans to become a primordial soup for life.Some hypotheses also claim that this was also possible in the bottom of the ocean in the hydrothermal vents when the earth was even hotter and more active.

There is a small difference between the difficulty of substances to cross a cell membrane since the diffusion of substances through cell membranes always occurs going down by gradients of concentration. It does not require an energy expenditure (ATP).Plasma membranes have selective permeability. Different molecules move in different regions and at different speeds. A concentration gradient directs the three types of passive transport: simple diffusion, facilitated diffusion and osmosis.
