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.]

Question 9 (4 pts)

The genetic term “loss of function” is used to describe any mutation in the DNA that leads to a particular protein that cannot function. There are many reasons why a protein may not be functioning any longer…digging into your knowledge on mechanism of gene expression and gene expression regulation, describe a mutation that could lead to a loss of function mutation. Where is the mutation in the gene? What function of gene expression or gene expression regulation is it affecting? How is it leading to a loss of function for the protein encoded for within that gene?

But I’m going to restrict your answer…describe a mechanism that DOES NOT include a point mutation leading to missense, nonsense or frameshift – in other words, choose a mutation/mechanism other than a mutation that leads to a change in the protein coding region of a mature mRNA. I want you to think outside of that particular box.
