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:
It is double stranded DNA, and it could be from an eukaryote, a prokaryote or a virus.
Explanation:
You can rule out the possibility of the nucleic acid being RNA because of the presence of thymine, which is absent in RNA, and is replaced by the base Uracil. In double stranded DNA, guanine pairs with cytosine, and thymine pairs with adenine, so the proportions of A and T, as well as those of C and G, should be the same. This is consistent with the information given, so you can conclude that it is indeed double stranded (this can also be concluded simply by the fact that it is DNA, because this type of nucleic acid is always double stranded).
All types of organisms can have a DNA genome, so it could either belong to eukaryotes, prokaryotes, or viruses. If it were RNA, it would only be possible for it to belong to a virus, since they are the only ones that can have an RNA genome.
In the case of fish if you polute plastic into the ocean the water will break up the plastic and the fish will confuse the little particles of plastic as food and will try to eat it and can die

Explanation: is correct
Answer: Neutrophils exhibit pseudopodia.
Neutrophils flatten and squeeze between the endothelial cells of capillary walls as a response to stimuli and cell adhession molecules on the endothelial walls.
Explanation:
Neutrophils are white blood cells that play major role in immune system. They circulate round the bloodstream and when they sense pathogens in the body, they move to the site and start killing the invading bacteria.
Neutrophils flatten and squeeze between the endothelial cells of capillary walls as a response to stimuli and cell adhession molecules on the endothelial walls.
