The CRT exam will be on April 19th and will cover topics we have discussed during the second semester such as evolution, taxonomy, and ecology. I am creating a review presentation to help you prepare.
CRT Prezi
Please post any questions you might have in the comment section on this blog.
This is a good presentation! But I think you should do more about Evolution and Darwin and Lemarck. That's kind of the hard part for me. I missed a lot on the test today.(EVOLUTION test)! -Nisey ♥
ReplyDeleteI added some more information on evolution. If I have time I'll add some stuff on ecology also.
ReplyDeleteWhat is a easy way to remember the diffrence between LeMark and Darwin's theories of Evolution?
ReplyDeleteI get them confused and mixed up!
----Lisbet (:
Maybe we should go over some cladograms and dichotomus keys again just as a refresher.
ReplyDeleteWhat is the difference between emigration and immigration? ? -Nisey ♥
ReplyDeleteEmigration = leaving a population [Exit]
ReplyDeleteImmigration = entering a population [Into]
This is great, its lays out the info clearly and easily to understand. Its much easier than flipping through packets when you are just trying to review the main points. -Aida
ReplyDeleteThanks Mr.DuPuis!!! This is a much easier way to review key points just before a big exam! I feel great about the CRT but if we have time during bellwork we should review Darwin and Lamark
ReplyDeleteMy questions the same as Lisbet. What is a way we can tell the diffrence between LeMark and Darwin's theories of Evolution?
ReplyDeleteI need a easy way to remember Darwin and LeMark theories i get confused on them
ReplyDeleteOn the CRT reveiw how is true bacteria prokaryote instead of eukaryote?
ReplyDeleteWhat is the difference between an analogous structure and homologous structure?
ReplyDeleteSM: Eubacteria is a prokaryote, it has no nucleus. Do not be confused by the EU prefix, if it a type of bacteria [eu or archea] then it is a PROkaryote].
ReplyDeleteThe other 4 kingdoms Protista, Fungi, Plantae, and Animalia are all EUkaryotes.
Heyy the CRT Review Presentation was great and it helps a myriad to get the key point!
ReplyDeleteLike my fellow peers above I also get mixed up with Darwin and LaMarck so if you can help out with that, that would be great!! -Erick Basilio
ReplyDeleteI noticed we had a question over the quiz-quiz trade portions of class we did that involved radiation. I know the correct answer was half-life, but I don't remember the question nor do I remember studying radiation. Could you explain it a bit better to me so I understand it better? How would I come about remembering and/or answering the question if it shows up on the CRT? Thank you.
ReplyDeleteAnalogous structures serve the same functions, but they are of different origins.
ReplyDeleteHomologous structures are of similar embryonic and ancestral origins, but serve different functions.

I have recently seen a lot of the term "Radioactive-dating" in some of the questions but I'm not sure what it means or if we even need to know what it means. We may have covered it in class, but I'm not sure. Will you clarify this please?

In the crt packet. it said darwins observation of finches having similar characteristics supported the theory of use and disuse. wasnt lamarck the one who did the use vs. disuse? -Sammy
ReplyDeleteSammy, Lamark's theory was use vs disuse. The finches did not support use disuse, they are an example of adaptive radiation. Those with the beaks that were best adapted to their niche survived and passed on their genes.
ReplyDeletewhats the major difference between eubacteria and archebacteria?
ReplyDeleteRadioactive dating is used for estimating the age of fossils. This works because there are naturally occurring radioactive isotopes that we consume during our lifetime such as carbon 14. When an organism dies they no longer ingest more carbon 14 and the isotope begins to decay. This is where half life comes in. Isotopes decay at a known rate. A sample of carbon 14 has a half life of 5700 years, in other words half of the mass of the sample will decay in about 5700 years. For very ancient fossils other isotopes are used because they have a much longer half life. See page 420 in the text book for more details.
ReplyDeleteThe Nitrogen and Carbon cycles are still a little fuzzy to me. Is there any helpful last minute pointers to help me out with these cycles?
ReplyDeleteThanks,
Sydney R.
Do you know any tricks to memorizing the characteristics of all the kingdoms?
ReplyDeleteDo you know of any useful websites that could help me review the nitrogen and carbon cycle?
ReplyDeleteRemembering these topics takes a bit of time studying. I don't have any great online links for these biogeochemical cycles, but the worksheets you completed in class were as clear as any diagram I have found online, not too simple and not too complex. Also your comp book or text book are excellent resources for any of these questions.
ReplyDeleteHere is a site I like with great info about the carbon cycle, but it is more information with more details than you need for the CRT test.
http://earthobservatory.nasa.gov/Features/CarbonCycle/carbon_cycle4.php
Maybe a way to focus on these cycles is too look at how these molecules move, follow the path so the journey makes sense. Carbon goes from the atmosphere into a plant and changed into carbohydrates. These can be eaten by animals and the exhaled as carbon dioxide, or stored as fat or protein. Or the organism can die and carbon goes into the soil. It can be burned and released into the atmosphere. There are many different possibilities, but you only need to read the question carefully and choose the best answer tomorrow.
Good luck, I believe in you. I know you will do great.
