Before reading these articles, state your current knowledge and opinion about the importance of pollinators to plants and other organisms such as humans. Then read about from the websites of Colony collapse of bees and colony collapse disorder. Then answer the following questions:
Define colony collapse disorder. and why we should be concerned. If you do not think this is a concern state your evidence for this opinion as well.
Are you surprised by the economic impact of colony collapse disorder?
If pollinators are eliminated in an ecosystem how will this affect the genetic diversity of the population?
What should or could be done to limit the effect of or help eliminate this problem?

2) Briefly describe the absolute refractory period in relation to V-gated sodium channels, V-gated potassium channels, and the membrane permeability to those ions.
3) When you determined the relative refractory period, you actually recorded the interval when a few neurons entered the relative refractory period. Explain why this interval signifies the beginning of the relative refractory period and not the absolute refractory period.

In rats, gene B produces black coat color if the genotype is B–, but black pigment is not produced if the genotype is bb. At an independent locus, gene D produces yellow pigment if the genotype is D–, but no pigment is produced when the genotype is dd. Production of both pigments results in brown coat color. If neither pigment is produced, coat color is cream. Determine the genotypes of parents of litters with the following phenotype distributions. |
