Variation in the appearance of guppy color patterns to guppies and their predators under different visual conditions.
kompoz [17]

Color patterns can be thought of as mosaics of different-sized, form, brilliant, and colored patches. A number of natural conditions, including ambient light, watercolor, viewing distance, and the visual capabilities of guppies and three of their predators, were used to assess how noticeable guppy color patterns were.

A particular color pattern element (patch reflectance )'s spectrum, the medium's transmission spectrum, and the ambient light spectrum that strikes the patch all interact to determine the light spectrum that reaches the eye's surface (air or water).

The light at distance x from the patch that reaches the eye at any given wavelength, I, is the result: Q(& x) is the photon flux from the patch reaching the eye (patch radiance), and Q(A) is the photon flux of ambient light incident on the patch.  

Predation intensity varies spatially with guppy color patterns, which are influenced by the make-up of the predator communities (Endler, 1978). As a result, calculations were made independently for the color patterns of guppies that are unique to three different predator communities.

You are working in the lab and want to use a microscope to examine the fimbriae of a bacterium at the highest magnification poss
Dmitrij [34]
<h3>Short Answer: False</h3>

Long Answer: Yes, sort of. You do use a scanning microscope to start, as you will want to move the microscope to the correct location before increasing the magnification. However, you wouldn't use the scanning lens to see with high magnification.
