in an episode of cosmos by carl sagan , he states that all life is made up of 'bitts' i.e. a 'bitt' representing the answer to a yes or no question -similar to the game twenty questions. an example of this would be for a dog 'does it have fur' -yes (1 bitt) 'does it have four legs' -yes (2 bitts) this means that all life and creation is the result of a genetic pattern of yes and no answers which , when put together , create a gam of not 20 but millions of questions.

however all questions and answers have an equall opposing answer that just cancels it out and some questions even cancel themselves out for. therfore if all question cancel themselves out in some form how do we exist ? are we nothing?

How do you indicate the number of atoms in a covalent compound?

For example, I don't understand these:

NO3 -
Why is it 1(mono)?

PO4 3-
Why is it 3 (tri)?

IO3 -
Why is it 4 (tetra)?

MnO4 -
Why is it 7 (hepta)?

SO3 2-
Why is it 10 (deca)?

Please, PLEASE help!
I have a quiz on this tomorrow.
It was part of my summer homework so I didn't have any instructor teaching me, I was supposed to teach everything to myself but this was the one part I didn't get.

it is obvious that there is an outer space however if it is eventually proven that there i inner space (i.e. the space between atoms)could that mean it is possible that we do not exist in outer space but instead on an atomic scale betwixt something far larger- on an impossible scale?

This is a mind-boggler to me and I'm wondering if any biology geniuses out there have the answer (...and if it involves religion, I'm spamming your account with naughty emails). Anyways, we all know asexual organisms clone themselves to produce an exact copy of itself, whereas sexual organisms combine DNA and create something with variation. Now, I'm wondering, since asexual organisms supposedly came first, how did evolution create sexual organisms. Obviously asexual organisms weren't just like "Let's combine our DNA to make something with variation and a better chance for survivial in a catastrophe!" What happened? How did cloning (asexual reproduction) turn into sex (sexual reproduction)? Mother nature really is intelligent.
