<p>I think everyone is almost ready for the Biology E/M exam next Saturday.
So, Why don't we all review together? We can ask questions.. Review
certain topics.. This way we can help each other before the exam !!
Hope everyone participates!</p>
<p>I'll start off by asking about the different types of evolution E.G. : Divergent.
Because am having trouble setting them into my head :P</p>
<p>Divergent Evolution is when a species is split into two, and they “diverge” methods of survival. For example, one species of salamander is split in two somehow, and one develops a longer tail, and the other loses its tail.</p>
<p>Convergent Evolution can be easily defined by a dolphin and a shark. They are different species, but both adapt to survive in a similar fashion (fins and stuff). </p>
<p>Parallel Evolution is similar to Divergent Evolution, a species is split into two. But instead of developing different characteristics, over time, their characteristics still seem similar.</p>
<p>Coevolution is when two species evolve together. A hummingbird and a flower. Say the flower develops a longer something, and the hummingbird has to adapt to reach the nectar in the longer something, I forgot what they are called =P.</p>
<p>Adaptive Radiation is Darwin’s finches.</p>
<p>BiologyHate : Thanks aloot for This Topic …</p>
<p>My Que: What about The Stages of Menstrual Cycle With role for Each Hormone ?</p>
<p>Hey. I’m doing some biology revision too. </p>
<p>I’ll dont mind helping out. I was really nervous when I took my SAT IIs especially the self-studied ones. </p>
<p>Thanks for creating this thread btw!</p>
<p>Bummmmmmmmmmmmmmmmmmp</p>
<p>examples of Natural selection and discuss it please</p>
<p>@Lometa: I haven’t gotten to that review section yet, sorry.</p>
<p>@Shalaby: </p>
<p>Let’s give a scenario to make this simpler. So there is a large population of rats on an island, and they vary in color from white to black.</p>
<p>Directional: Over time, one color is preferred over the other. Black ones survive more because forests are growing more rapid, and black blends better, so they survive more.</p>
<p>Stabilizing: Neither extreme color is preferred, but rather in the middle. So say gray or brown ones survive instead of white/black.</p>
<p>Disruptive or Diversifying: Where both extremes are preferred, but nothing in the middle. So only black or white survive, but no gray/brown.</p>
<p>“Adaptive Radiation is Darwin’s finches.”</p>
<p>Can someone explain this in a little more detail?</p>
<p>The finches migrated to the islands as one species. But over time, each population’s characteristics changed to suit the island’s specific characteristics. An island with more harder shells on seeds caused birds to adapt with stronger or larger beaks.</p>
<p>@Lomenta & everyone
I’ll try to write whatever I can, please add on too everyone!! </p>
<p>Topic: Stages of Mensural Cycle (MC)</p>
<p>There are 2 cycles in the MC a) Uterine Cycle b) Ovarian Cycle</p>
<p>Uterine Cycle:
<p>2) Proliferative Phase: Day 5 - Day 14
<p>3) Secretory Phase: Day 14 - Day 28
<p>Ovarian Cycle:
<p>2) Ovulation: Day 14
<p>3) Luteal Phase: Day 14 - Day 28
<p>Question!: Do we need to remember the specific sequence recognized by restriction enzymes? And the name of the enzyme and where it was found?</p>
<p>Example: EcoRI found in E. coli.
5’-GAATTC-3’</p>
<p>Please and thank you!</p>
<p>THX aloot myeyeballs …</p>
<p>Myeyeballs, probably not. That would be extremely stupid. Even the Barrons test didn’t have questions like that.</p>
<p>what about Question of Genome of DNA ?</p>
<p>Is any one reviewing from the AP Biology (Cliffnotes)?
Any tips on what to skim and what is good info to learn?</p>
<p>I’m taking the SAT Biology SparkNote tests for revision…
There are 5 tests, I think.
If you guys have taken them, post the scores!
I’ll post mine when I’m done.</p>
<p>What’s the difference between lymph vessels and lymph nodes?</p>
<p>Bump 
@Biologyhate help? </p>
<p>Also, did you guys remember the parts of the urinary system?
Eg: Afferent arteriole, Proximal convoluted tubule, Loop of Henle, etc.</p>
<p>Lymph NODES are connected to one another by lymphatic VESSELS.</p>
<p>Yes I remember the kidney stuff.</p>
<p>Here’s a good challenge: describe the photosynthesis processes! :)</p>
<p>Please Help meeeeeeeeeeeeeeeeeeee in Endosymbiosis Theory :S:S</p>
