My daughter is in a required Biology class and is a sophomore in H.S. Her teacher who is new this year had them bring in a live insect...or something without a backbone. Someone brought in a crawdad and the teacher held it up and said, let's see what its tolerance for pain is, and pulled one of its legs off while it was still alive! He was having them poke and prod things while they were alive. This made her heartsick, and her father and I as well. Called principal this morn, and he informed me that all he could do was make sure she was assigned a different assignment, but that he didn't see anything wrong with it. He talked like it was out of his hands and he informed me.."Well, we disect animals" I said, not when they are alive! Hubby talked to Superint. and he says he will look into it. What is your view? Do you think he is encouraging cruelty to living things( the teacher)? Do you think the principal handled this right? I think they are cruel. B4 disecting, they should be dead.

How long do you have to fast before you can consider your stomach "empty"? As in that the pills you take will not mix with any food?

Thanks!

P.S.

(only one allele is present rather than two). If there is only one allele, do you have to know whether it is a dominant or recessive allele in order to know whether it will be expressed? Discuss.
