<p>S phase</p>
<p>What are the stages of the Cell Cycle, in order?</p>
<p>tehcakeisaLIE its in the barrons book you know it now. Im not guessing, YOU KNOW IT NAAOOO.</p>
<p>Edit: phases of cell cycle:</p>
<p>Interphase - G1 S G2 phase (including G0)</p>
<p>Mitosis- prophase, prometaphase, metaphase, anaphase, telophase</p>
<p>cytokinesis.</p>
<p>interphase (G1, S, G2), mitosis w/ telokinesis and cytokinesis</p>
<p>Does anyone know where I can find a review site with visual aids or explanations for important biological process’?</p>
<p>Thanks alot.</p>

<p>involves neurons and the autonomic nervous (system?</p>
<p>(@darkflame)</p>
<p>I believe that involves a reflex arc which consists of a sensory neuron connected to an interneuron, which is directly connected to a motor neuron that moves a muscle. Yes?</p>
<p>Discuss the differences between the sympathetic and parasympathetic divisions of the autonomic nervous system.</p>
<p>The sympathetic nervous system causes the eyes to dilate and inhibits the salivary glands from secreting saliva. It is the initial reaction to something sudden or to an emergency, such as nearly escaping death. The parasympathetic nervous system is the set of reactions after the event. It is characterized by secretion of saliva.</p>
<p>After checking my book, I realize that a better wording of my description for the sympathetic nervous system is the nervous system involved with the “flight-or-fight” response. In addition, the parasympathetic nervous system also initiates secretion of digestive enzymes in the stomach.</p>
<p>Question: In the human digestive system, there are several specialized organs for the digestion of various molecules. From the list below, choose 2 organs, list what is digested there, and explain the processes of digestion in those organs. In addition, list the enzymes or fluids used in those organs.</p>
<p>Stomach
Small Intestine
Liver
Pancreas</p>
<p>@Darkflame: It is a reflex arc involving a sensory receptor (thermorececptor) that stimulates a sensory neuron (afferent neuron). The action potential propagates and reaches the spinal cord. The afferent stimulates an association neuron that will in turn stimulate a motor (efferent neuron) to fire. The motor neuron will then trigger a response in the effector organ in this case the shoulder, arm, hand, etc. </p>
<p>Also this response is NOT part of the autonomic nervous system. IT IS PART OF THE SOMATIC NERVOUS SYSTEM, because the effector organs are skeletal muscles. Other reflex arcs include patellar tendon, sneezing, and a few more. </p>
<p>@Happy Panda:</p>
<p>Small Intestine - Bile produced by the liver and stored in the gall bladder is released in the small intestine. It is able to emulsify lipids and absorb nutrients from them. </p>
<p>Stomach - pepsin and amalyase (sp?) are the enzymes. Pepsin breaks down proteins and amalyase can further break down carbohydrates that were not broken down in the mouth.</p>
<p>What are five ways evolution occurs?</p>
<p>5 ways of evolution: genetic drift(includes bottleneck and founders effect), gene flow, mutation, outbreeding, and natural selection. Note, these are the factors that can not occur to maintain hardy weinberg equilibrium.</p>
<p>^Isn’t outbreeding and gene flow essentially the same thing: migration?</p>
<p>Genetic Drift has two ways: Bottleneck & Founder
Gene Flow/Outbreeding/Migration
Mutation
Natural Selection</p>
<p>^I think outbreeding is the same as nonrandomm mating</p>
<p>I looked it up and according to wikipedia:</p>
<p>In evolutionary biology, outbreeding depression refers to cases when offspring from crosses between individuals from different populations have lower fitness than progeny from crosses between individuals from the same population.</p>
<p>So its similar to gene flow (different populations), but then natural selection acts on them.</p>
<p>@stigmatamartyr google McGraw hill mader biology animations; they’re amazing! </p>
<p>I have a question about functional groups. How do you “recognize” them? I have carbonyl carboxyl hydroxyl etc memorized but would they give us a diagram with the group attached or just the functional group itself?</p>
<p>AND</p>
<p>Do roundworms belong to annelids or a different phylum?</p>
<p>Round worms belong to the phlyum nematoda.</p>
<p>Earthworms are annelids.</p>
<p>I took the test last year and there were a lot of questions about plants…I don’t know if they switch around their topics from year to year but that was it.</p>
<p>Earthworms are annelids. Roundworms are Nematods. </p>

<p>On one of the practice tests, they had a list of unnamed functional groups (so they were diagramed) and they had four named molecules without a diagram that you had to match with the functional group. So, for functional groups, know what each one looks like and how a corresponding molecule with said group is named.</p>
<p>Oh yeah, I think that was 1994, you also had to know what hemoglobin looked like for that… =)</p>
