Please see the Announcement on this board. Folk here will not do your homework for you but will help if you're stuck on something.

Pasting what appears to be an entire quiz is a but much.

oh you have got to be kidding me.

here. a little gift. you seem to be one of those students, like i used to teach on occasion, who thought getting the answers from others would float you through class. you might even "understand" why an answer was right after you were told. then you take a test. hmmmmm.... didn't go as well as you'd like? i've had students balling their eyes out because they "understood" the answers they got in their "study groups" but then got slammed on the exam.

so here's the "gift" - if the questions are directly out of a college textbook there is often a supplemental book you can buy (might not be in the bookstore, need to look online) that has all the answers. its also has explanaions, but from your post it looks like you are not interested in learning anything.

the nature of the questions look to be a general bio class... a little chem thrown in there but bio related. i hope this is the only science class you need to take. you are not even to the hard stuff, or intersting stuff, or the stuff that makes a career, a degree, a doctor, a scientist, a knowledgable person, and you're taking the easy way out.

hope you aren't taking out too many loans or making your parents go into debt.
