What is natural selection (not from google) give an example of what natural selection is
ruslelena [56]
Natural selection is nature’s way of keeping the best fit-to-live things alive, and so on continue to the next generations.

For example, if a rabbit has a limp, it is bound to be out run and eaten by a predator relatively early in its life (unless it is extremely lucky.) Because of this, it is unable to reproduce, and there genes that it contained to have its limp are unable to spread through inheritance. Natural selection goes both ways. For example, if a hawk has very god vision, it will be able to scope out its prey easily, so it will thrive. Therefore, when it produces offspring of its own, its trait of good eyesight will pass on to its offspring.

So, as enough time goes on, the bad traits will be weeded out and the good ones will remain.

Bacteria can make their own folic acid, which is required for nucleic acid synthesis, but humans cannot and instead have to inge
lidiya [134]

This drug inhibits the growth of bacterial cells but not human cells. This is an example of the selective toxicity of antibiotics.

Folic acid is an essential component for all cells to synthesize nucleic acids (DNA and RNA). Human cells do not synthesize folic acid and they take it through food. Bacterial cells are impermeable to folic acid and hence they need to synthesize their own folic acid.

Antibiotics target the metabolic pathway of folic acid synthesis in bacteria by inhibiting one of the enzymes in this pathway. These drugs are only toxic to bacteria but not to humans because humans do not have the folic acid synthesis pathway and hence they do not get affected by the action of the antibiotic. This is known as the selective toxicity of antibiotics.

These antibiotics are designed in a way to target the infecting agent (bacteria) while rendering minimal or no toxicity to the host (humans).
