Question

In a laboratory experiment, C. elegans and B. thuringiensis were cultured individually (control) or together (experimental) for 150 days. Under optimal conditions, the generation time of C. elegans is approximately 3.5 days and the generation time of B. thuringiensis is approximately 25 minutes. At the end of the experiment, the change in virulence of B. thuringiensis and the change in resistance of C. elegans to BT toxin were determined. (a) Calculate the maximum number of generations that is possible in individual cultures of C. elegans AND the maximum number of generations that is possible in individual cultures of B. thuringiensis in 150 days.

Answer 1

Answer:

Explanation:

If the investigator wishes to watch the movement of C. Elegans (a roundworm), then he should be using compound microscopes. These microscopes are light illuminates and image that can be perceived is a two dimensional. Using this would allow you to magnify to a certain level so you can view individual cells and even cells that are living and moving. Typically compound microscopes can magnify up to 1000 times magnification. It has two convex lenses which has short focal lengths to allow a much higher level of magnification as compared to a simple microscope. These lenses are called the ocular lens and the objective lens.
