<p>I heard that there are now 6 kingdoms instad of 5. what are they and how are they different form the old?</p>
<p>what do we really need to know about the labs? I dont have the class so I didn't do any of the labs this year, but I feel I can BS my way through the exam. I took a couple of released exams, and for the multiple choice, I just read the graphs and charts and use my knowledge of biology to answer the question (and usually get it right- hope that trend continues). If I need to design an experiment for the free response, I can just make one up on the fly by using my knowledge of biology and a basic a laboratory and experiment knowledge (control groups, chaning one variable, etc) </p>
<p>The AP Bio teach at my school gave me a disk with labs and I will probly read through the cliffnotes about the labs. But I have a feeling I'm wasting my time. </p>
<p>someone prove me wrong?</p>
<p>..uhhh i think there's just 5 kingoms</p>
<p>The accepted system is still a 5-kingdom system. There is a movement toward a Domain system, headed by Carl Woess, though, the domains being Eukaryotes, Archae, and Eubacteria. I don't know whether anything concerning that would be on the AP exam, though.</p>
<p>As far as the labs, it's true that the m.c. questions that involve lab-related activities aren't too difficult. As far as free response questions that involve "designing labs," you can still easily get a 5 without even answering this question if you do well on the multiple choice and decently on the other free response questions -- it's likely that you could get a few points from that without an extensive lab experience, though.</p>
<p>I don't think going over the labs right now is going to help. You probably won't remember enough where it's going to make a difference, so that time would be better spent reviewing things that you <em>do</em> know, but could know a little bit better...</p>
<p>thanks zach. I was getting bored after the first minute of lab "review" anyway :-P</p>
<p>the domain system is becoming more accepted. On the 1999 AP, there was an essay on the movement from the 5 kingdom system to the domain system. I have heard of a six kingdom system as well, though not very often, and cant even remember where i heard it from. Its the splitting of monera into eubacteria and archaea. So there are three systems you should watch out for: 5 kingdom, 6 kingdom, and domain. But in today's world, no one knows which to study. I wonder if college board even says which one to prepare for... All i have to say is classification sucks. And if you dont know the labs by now... dont bother starting</p>
<p>what is hte domain system?</p>
<p>The domain system has three domains: Eukarya, Archaebacteria, and Eubacteria. Eukarya has all four of the old eukaryotic kingdoms(fungi, protista, plantae, and animalia). Archaebacteria and Eubacteria are both prokaryotic, but archaebacteria is more closely related to eukarya than it is to eubacteria. If you learned the kingdom system, then archaebacteria and eubacteria were both part of kingdom monera, but because of evidence showing that Archaea and Eubacteria were not very closely related, the Kingdom monera was shut down, and thus archaebacteria and eubacteria became their own domains. Archaebacteria are obviously the archaea (the ones that lived in really harsh conditions) from monera and eubacteria were the other bacteria (the more commonly discussed ones). According to the domain system, the common ancestor gave rise to two lineages. One became Domain Eubacteria. The other lineage broke off into two other lineages: One was Archaea and the other Eukarya. The eukaryotic system remains more or less untouched for our purposes (i think some species are uder consideration, but we dont need to know them). So yeah, thats domains in a nutshell. Dont any other textbooks discuss this topic? Our book didnt even discuss kingdoms, lol. Anyway, yeah. There you go.</p>
