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).

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.

i. Why does Darwin believe that nature has put such a premium upon the enhanced survival skills of certain creatures?
ii. Darwin compares natural selection to a country undergoing some form of climate change. How does he say that such an example and climate change are similar?
iii. Darwin argues that the hand of "natural selection is daily and hourly scrutinising, throughout the world, the slightest variations; rejecting those that are bad, preserving and adding up all that are good; silently and insensibly working, whenever and where opportunity offers, at the improvement of each organic being in relation to its organic and inorganic conditions of life." If Darwin is correct, how come we don't see people, animals, and other organisms morphing before our eyes?
iv. What makes leaf-eating insects green, bark-eating insects mottled grey, and gives hawks such good eyesight? What happened to the insects of the wrong color or the near-sighted hawks?
v. How could this view of the role(s) played by the laws of nature upon the rest of the animal kingdom (yes, you are a part of the animal kingdom: the ape family) be interpreted to apply to human interactions? After reading this kind of expose, what reason might some give for poverty, disease, or the domination of one people over another? [I do not mean to suggest that it should be applied, completely, to the understanding of human interactions, but some did, and I am setting the stage for that movement.]
