A virologist has a cell-free extract of herpes simplex virus (HSV) that has a titer of 6 x 106 infectious virus particles/mL. Th
is virus forms plaques on monolayers of the monkey kidney cell line, CV-1. Following completion of a 10-fold dilution series, the virologist plates 100 microliters of each sample in duplicate. Required:
What experimental results did he MOST LIKELY observe in the duplicate plates corresponding to his 1:10000 dilution?
If populations don't change very much over time, the ecosystem is in equilibrium .Populations decrease at higher levels of the food chain because they require more energy from other organisms.
