Tarcísio Brito: It describes the life in the Land (infinite), where all species also the man has certainly ancestral origin, where a trip for front (for the future) results in an arrival to the past of Daily pay-History; e that finishes in return to the gift of Our Historia. I circulate that our alternating History of Daily pay-History is happened again infinitely.

I am leading a lab in my Advanced Bio class (I'm a senior in high school). I wanted to try to do something other than the 12 standard AP Bio labs. It would be good if it could be done in a class of 20 students . If you don't have an idea, can you think of an interesting topic that I could search for an experiment on?

Epithelial tissue, connective tissue, muscle tissue, or nervous tissue?
I think it's epithelial, but epithelial tissue is supported by connective tissue...so would it be connective?

I know it is a theory, but how can people believe it? How can people believe that every single living organism evolved from a common ancestor? I mean like...that would mean we were related to..snails and grass?
Before you go any further, here's some questions:
1. Where did the space for the universe come from?
2. How did matter get so perfectly organized?
3. Is it possible that similarities in design between different animals prove a common creator instead of a common ancestor?
4. Natural selection onlyw orks iwth the genetic info availabe and tends only to keep a species stable. How would you explain the increasing complexity in the genetic code that must have occurred if evolution were true???

My son is doing a science project to determine which "animal" has the dirtiest mouth. We have sterile cotton swabs to collect the samples. Do we need to put them in a sterile saline solution first, or will the saliva be wet enough to get a good sample? Also, is it best to rub the swab on the agar or roll it on--does it really matter which method is used? Thanks in advance!

It doesn't make scense to me. Is it just the climate some one lives in that determines what race a person is? Like Asian and Latin people; how did they get the certain physical fetures that are so diffrent form every one else? Is it just clearly genetics?
