<p>Hoping for a 5. But at point, it seems like a 3 or 4 is more probable :/.</p>
<p>We literally spent a whole month on just 1 chapter…ugh.</p>
<p>
</p>
<p>Cliffs, IMO.</p>
<p>I have never consulted Princeton Review, but I have learned quite a bit from Cliffs.</p>
<p>If my teacher on the way he curves his tests, then I should definitely get a 5 unless I blow all the essays or MC</p>
<p>Hopefully 4-5. Want a 5 though.</p>
<p>Question: Name the four basic tissue types of animals.</p>
<p>This is just a guess but dermal, skeletal, connective, and organs?</p>
<p>
</p>
<p>I believe the four main tissues are connective, epithelial, muscle, and nervous.</p>
<p>mifune is correct.</p>

<p>I have a test that includes spermatogenesis and oogenesis, but it was never really taught to me in depth. Can someone explain these?</p>
<p>
</p>
<p>Spermatogenesis and oogenesis are basically different versions of meiosis:</p>
<p>Oogeneisis = development of mature ova (eggs)
It basically starts with a differentiated cell, oogonium (2n) from the ovary that will undergo mitosis at first. Eventually, one of the oogonium will undergo meiosis, but it will be arrested at prophase in meiosis I; at this point it is known as primary oocyte. At the beginning of puberty, the primary oocyte, triggered by hormones, will complete meiosis I. Because of unequal cytokinesis following meiosis I, the smaller of the two cells will become a polar body and simply degenerate while the larger cell (known as the secondary oocyte) will undergo meiosis II. However, the secondary oocyte will only follow through meiosis II to completion when it is penetrated by a sperm cell , resulting in the formation of an ovum. Once again, due to unequal cytokinesis, one of the cells becomes an nonfunctional polar body (second polar body). When the nuclei of both the egg cell and sperm fuse, fertilization occurs. </p>
<p>Spermatogenesis = produce of mature sperm (continuous lifelong process)
Spermatogenesis starts off spermatogonium, that will divide mitotically to form a large number of spermatogonia. One of these spermatogonia will go through meoisis I (then known as primary spermatocyte) and divide to form two haploid secondary spermatocytes. Meiosis II will take place, resulting in a total of 4 haploid spermatids. The spermatids will differentiate and develop into the full form of a sperm cell by producing a flagellum, acrosome, and head (which is known sperm cells)</p>
<p>Note: unequal cytokinesis is a feature of only oogenesis. </p>
<p>Hopefully that helps…</p>
<p>I agree w/ B</p>
<p>Question: Describe gel electrophoresis.</p>
<p>Substances are placed in hallows in the gel. The gel is immersed in water with electrolytes (like salt water) in a small tub, and an electric current runs through the tub. The tub has a negative side and positive side, and the substance moves in different directions and at different speeds depending on its size and charge. This helps us find similarities and differences in molecules like DNA and proteins as well as identify them.</p>
<p>Protists are ridiculous. They change every day, and different school systems/states use different versions of biology textbooks. Some groups of them no longer exist, and new ones are currently being created. How are you guys tackling learning about protista?</p>
<p>^ my teacher says they are really insignificant. I would just get the basic idea of reporudction and how they get food, but that’s about it. Rather than trying to get down these tiny details I would spend more time on the common tested subjects.</p>
<p>Thanks, Indianjatt! That’s a good idea… honestly, how many questions can the test makers actually ask about Protists? 
</p>
<p>Just wondering, does any one use Campbell Reece 8th (AP) Edition Biology?</p>
<p>
</p>
<p>I agree. A basic knowledge of protists is fine but time is best invested elsewhere.</p>
<p>What is everyones favorite topic? Least favorite?</p>
<p>Favorite: probably some cellular stuff</p>
<p>least: plants</p>
