What do you hypothesize is causing the bubble at the top? From what you know about plants, if we were to place one of the test tube and beaker combinations in a dark closet, what would happen? If we placed a green light (as opposed to white or natural light) […]

The two biochemical pathways for coat color pigment in a species of triblles are shown below. The final color of the tribble is the combination of colors produced by the two pathways. If both blue and yellow pigments are produced, the coat color is green. If both blue and red […]

In the Fender’s blue simulation you explored in Exercise 2 of this lab (Hot and Bothered), with periodic fires turned ON, which patch configuration is likely to be better for Fender’s blue butterfly persistence, and why? The Small Near configuration, because butterflies can more easily recolonize patches that burned The Small Near configuration, because […]

In the plant genus Triticum there are many different polyploid species, as well as diploid species. Crosses were made between three different species, and hybrids were obtained. The meiotic pairing was observed in each hybrid, and this is recorded in the following table. (A bivalent is two homologous chromosomes paired […]
