It must be 500 words. please help. Prompt: "The study of viruses demonstrates scientific method in action as biologists debate about whether viruses should be included in the tree of life or not."

1. Thesis:

Here you propose your thoughts and ideas about the prompt and provide support with examples and assumptions from the sources.
Pick a side as to whether you believe viruses should be included in the tree of life or not based on the articles and what we've discussed in class.
2. Antithesis:

Here you acknowledge the other side of the issue and explain the reasonings of the other side. Provide support with examples and assumptions from the sources.
3. Synthesis:

Here you try to bring the two sides together by proposing solutions or by discussing future implications.

the answer would be 3

i was thinking 4.0 v hope this

cells use diffusion to get substances in and out of themselves. that diffusion will occur across the cell membrane or the outer covering of the cell. because we are talking about the surface of the cell, surface area and volume are  important factors here. as a cell increases in size, its surface area and volume increase as well.  we call that the surface area to volume ratio (sa: vol).  but the catch is that  volume increases at a greater rate than surface  area. in other words, as a cell gets bigger, the sa: vol gets smaller. so a really small cell like bacteria is mostly cell membrane (surface) with very little contents (volume). a really big cell like an egg, is mostly insides with a super thin membrane. so what ends up happening is that the cell cannot efficiently diffuse all of the stuff it needs in/out to survive. therefore cell size is limited to about 100mm. so how do we make organisms bigger than 100mm? cells divide! by dividing and becoming multicellular, organisms are able to grow!   check out the diagrams i attached to see the effect of sa: vol. i hope this ! good luck!

i believe your answer would be c.. : )
