In three to five sentences, construct an argument for the claim that natural selection leads to evolution. Provide evidence for this claim, and be sure to explain how an organism shows the four parts of the process of natural selection. You may use any organism with the exception of bacteria and antibiotic resistance
Answers
Answer:
Natural selection is a process that leads to evolution. For example variation can lead to this. Say back then one giraffe had a long neck this variation had a chance of being passed down to their children. If it keeps getting passed down by natural selection because its helping the giraffe survive then more and more giraffes will have long necks. Over time if the trait is super beneficial it could lead to the evolution of all giraffes having a long neck.
Explanation:
I used the terms that go with natural selection. If its not correct im sorry i tried lol.
Answer:
Natural selection leads to evolution due to the way reproduction works. In the example of European moths during the industrial revolution, we can see this clearly. When the industrial revolution was going on, there was more pollution, hence darkening the skies and leaving ash. Moths, which before were white with occasional black spots dominated the area until pollution affected their environment. Whiter moths were eaten by birds who could easily see them against the black trees and skies. These moths could no longer reproduce, they were dead. Moths with more black could survive longer to reproduce because they were harder to see. As time went along, the moths turned mostly black, showing an example of evolution.

Describe how the malarial parasite affects a red blood cell in a person without the sickle-cell mutation (3-5 sentences):
Answers
Answer:
Invasion by the malaria parasite brings about extensive changes in the host red cells. These include loss of the normal discoid shape, increased rigidity of the membrane, elevated permeability to a wide variety of ionic and other species, and increased adhesiveness, most notably to endothelial surfaces. Now, sickle cells have membranes, stretched by their unusual shape, that become porous and leak nutrients that the parasites need to survive and the faulty cells eventually get eliminated quite fast by the organisms, destroying the parasite along the way.
