Due to the fact that sneezes & orgasms are similar actions, people who have dainty little cat-sneezes have smaller, less intense orgasms, and people with big loud, intense sneezes have big orgasms? Do you believe this? Anyone with medical training have any opinions?

I need to complete a punnett square for biology class and just can't figure it out. I have to fill out a cross concerning human blood and determine the phenotypic ratio for: (AB+-) x (AB+-)

If anyone can complete this it would be a great help.

I'm not a cleaning freak, but i'm concerned about my health and others. When we touch something, do germs stay there until we touch the thing again? example, A milk gallo. Lots of people probably touched the gallon I had purchased and then it goes into my refrigerator. Do a have those germs from many people inside there? do i have to wipe things off? This same question goes for everything that we or people touch and stays sit for months until we touch it again. How long germs live in one place?

Imagine that you were studying a primitive organism found on mars. Within this organsim, there are 2 compounds that look like promising possibilities for the hereditary material of the organism. Each compound contains an element NOT found in the other.
How could you use radioactive isoptopes to determine which of the 2 componds is replicated as the cells of the organism replicate & divide?
----
I don't really understand the uses of radioactive isotopes, I've been trying to read up on it- but it still doesn't make complete sense & I'm not quite sure how to apply it to situations like the one above. Can someone please help explain it to me. I would really appreciate it. Thank You! = )
