18. When considering the evolutionary tree of life and the three domains of life, which statement best describes what likely happened over the course of millions of years of evolution? Choose one:

A. Bacterial and eukaryotic cells are more closely related to each other than to archaeans, as evidenced by the fact that bacteria and eukaryotes do not inhabit the most extreme environments.
B. Although their cell structures are very different, archaean and eukaryotic cells are more closely related to each other than to bacteria, as evidenced by the fact that Bacteria was the first domain to split from the shared ancestor of Archaea and Eukarya.

C. Bacteria and archaeans are more closely related to each other than to eukaryotes, as evidenced by their cell structures. Bacteria and archaeans are prokaryotic, while all eukaryotic cells contain mitochondria and other membrane-bound organelles.
D. The three domains of life are equally divergent from one another, so no two domains are more closely related to each other. This is supported by the evolutionary tree of life because three branches extend from one node millions of years ago.

I want to know these two questions, and I want to get essay form

I heard you on ABC Breakfast talking of the full moon effect. Ihave suffered in no small way from it all my life and medicatemyself to sleep in a full moon, otherwise I don't sleep. As anengineer and science interested person I have thought a lot aboutthis phenomenon and have come up with a theory, which I'm verysurprised has not been considered previously. You said in yourarticle that gravity was excluded as a factor, but this is not thecase. Gravity is affected by the mass of the moon and it'sproximity to your location. The tides have complex interactionswith the earth and the sun, so making conclusions from the tidesalone is not always valid in relation to gravitational forces.Lakes are not tidally affected because there is no where for thewater to go. The ocean tidal waters don't go up and down like abath tub level, they go in and out like the waves on a beach. Iconclude that the increase of the gravitational force makessensitive people restless, and hence in a sleep lab, they are stillexposed to gravitational changes. I suggest the way to verify thisis to measure the gravitational force at different cycles of theearth and moon. I am also affected by air pressure in a similarway.When the air pressure is high, and it'sa full or near fullmoon, I'm unable to sleep without medication, and if I do partiallysleep, I have wild dreams. When the opposite is the case, I sleeplike the dead. Temperature is the other obvious variable thatexacerbates this cocktail of influences as well. Also, from anatural selection view, maybe we are restless at times of full moonas we are more visible to night predators, and need to keep morealert for that. As I said, I'm amazed that science hasn't resolvedthis question a long time ago. So much of nature is cycled by themoon.
