I have a few questions from a crayfish dissection worksheet..

1. When the crayfish is NOT walking, how does water move over the gills?

2. The carapace's most anterior point is called the rostrum. Why is it called this?

thanks! :)

I'm having a debate with my friend about the sentimentalities of organ transplants... she says that a transplanted heart (for example) is dead, but i am arguing that it beats, and becomes a part of your body in just the same way as a normal (original) heart (once it's been 'accepted' by the recipient)

Can anyone please mediate? (and ideally say your knowledge of the topic, i.e. I invented Organ Transplants)

I am a Christian who has learned enough about evoultion to know that I can't deny it. So I have tried to blend my faith and what I know about evoultion. I was wondering if anyone can show me if there are any holes in my idea, assuming for the sake of the question that there is a God. My thought is that God created the world and that the evidence for common ancestry could be expalined also by a common creator. So that the similarities throughout the different species shows not that we evolved from a single celled organism, but that everything was created by the same creator. I don't believe that the world that was created looks like it does today and that obviously many of the animals and plants would have looked a lot different that what we see today and that they have evolved to what they are now. I also don't believe that creation necessarily took place in 7 literal days. Please don't just tell me you think the Bible is a lie or that God doesn't exsist, that is another question

let us say there is a population of fish and they some how become separated into two populations, after awhile the two fish populations become one again. is speciation a necessary consequence of those events? why or why not?

According to the results of the Human Genome Project, scientists think that the entire human genome codes for only approximately 20 -30,000 genes. What classes are these genes? What percentage code for enzymes, structural proteins, proteglycans, receptors, hormones, transmembrane proteins, carrier or transport proteins, promoters, etc.? And how many genes do not make a known protein?
