Pretend you are trying to establish a specific species of mosquito as a model organism in order to design more effective pesticides. After sequencing the genome of Culiseta longiareolata, you uncover a gene that has a 54% sequence similarity to the oskar gene in the fruit fly Drosophila melanogaster. To begin determining if the oskar-like gene in the mosquito has a similar function to its potential homolog in the fruit fly, you’ve decided to first test if the oskar-like gene is a morphogen. How would you begin testing whether oskar-like is a morphogen? In your response, be sure to include which technique(s) you would use and your predicted result(s).

Define Poly-pharmacy. Research the implications of poly-pharmacy on the elderly. How can this be avoided. What needs to be done to safely administer medication to the older adult and insure compliance. Discuss alterations in the absorption, distribution, metabolism and excretion of medication in this age group. Share this information with your classmates.

Put the following steps of the light reactions in the correct order:

1. Light excites an electron from photosystem I.

2. Light excites an electron from photosystem II.

3. Electrons reduce NADP+ to NADPH.

4. Electrons pass through an electron transport chain, which generates an H+ gradient used to make ATP.
