30 points 1. After first exposure to an antigen, about how long does it take for antibodies to reach a detectable level?

2. What could explain the significant increase in antibodies to non-Lyme disease antigens (blue line)?

3. Lyme disease patients who are treated with antibiotics quickly usually do much better than those who are treated later. Why do you think this is the case?

4. Why doesn’t the Antibodies in Lyme Disease Antigens (orange line) decrease after the first immune response, compared to non-Lyme Disease Antigens (blue line)?

5. Professor Dr. Utpal Pal studied the Borrelia burgdorferi bacterium at the University of Maryland. Dr. Pal found that Lyme disease is caused by your immune system. When the body is infected with Lyme disease, it overreacts causing inflammation in the joints. Although antibiotic resistance has not been observed for B. burgdorferi, create an argument defending the control of antibiotic use to the public.

explanation:

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!
