<p>Never heard of that lol. Hopefully the questions aren’t that detailed… or maybe I just don’t know enough… :S</p>
<p>What is punctuated equilibrium and how does it disprove gradualism?</p>
<p>Evolution occurred in rapidly at different times (spread out times/bursts) due to different factors. Gradualism was that evolution occurred slowly and steadily. Fossil record?</p>
<p>Difference between vascular bundles and veins in monocots and dicots.</p>
<p>Difference between gymnosperm and angiosperm</p>
<p>monocots-scattered throughout the stem
dicots-centered around a ring
gymnosperm-cone-bearing and reproduced by spores
anigosperms-flowering plants and reproduce by seeds</p>
<p>salt,water and urea?</p>
<p>what is the maximum number of species that an environment can support called?</p>
<p>Equilibrium point ?? ( I am just guessing from what I did in maths class)</p>
<p>What is corpus leuteum structure ? What does it do ?</p>
<p>what is the maximum number of species that an environment can support called? </p>
<p>carrying capacity</p>
<p>What is corpus leuteum structure ? What does it do ?
develops from the follicle, after releasing the egg, after implantation, it is stimulated by the embryo to maintain the endothelium by releasing estrogen and progesterone</p>
<p>Dammit, I haven’t gotten to answer any questions yet.
Remember to ask questions, too, people :P</p>
<p>A) Nephridia
B) Nephrons
C) Flame Cells
D) Malpighian tubules</p>
<p>What are the respective excretory structures for each organism? (I usually see these kind of excretory structure problems on most review tests.)</p>
<ol>
<li>Planaria</li>
<li>Grasshopper</li>
<li>Earthworm</li>
<li>Britney Spears</li>
</ol>
<ol>
<li>flame cells</li>
<li>malpighian tubules</li>
<li>nephridia</li>
<li>nephrons</li>

<p>how is an action potential passed along?</p>
<p>So when the impulse reaches threshold, the Na+ gated channel opens which depolarizes the membrane by allowing Na+ back into the cell. Then, K+ channel opens which repolarizes the membrane by letting K+ out of the membrane. The alternation of depolarization and repolarization creates action potential. It happens the same along the axon.</p>
<p>With myelinated axons, impulse will jump from node to node so it is faster.</p>
<p>What enzymes are secreted into the duodenum, and from where ?</p>
<p>Amylase, Peptidase, Lipase, Nuclease… Don’t know from where, but I think the pancreas.</p>
<p>Now describe the chemical signals for the nervous system… as opposed to the electric above.</p>
<p>neueotransimitters are rleeased from the synaptic knobs into a synapse by exocytosis and they are are the stimulus for the dendrites of the next cell </p>
<p>if the precentage of a recessive allele in a population is 9% then what will the percentage of the heterozygous freqeuncy in that population be</p>
<p>Assuming that the population is in Hardy Weinberg Equilibrium, heterozygote frequency would be 42%.</p>
<p>The source of oxygen in carbohydrates produced by plants is</p>
<p>A. CO2
B. H2O
C. O2</p>
<p>The oxygen released from a plant comes from</p>
<p>A. CO2
B. H2O
C. O2</p>
<p>CO2</p>
<p>H20</p>
<p>by what process in aerobic respiration is most of the ATP produced?</p>
<p>Electron Transport Chain</p>
<p>What kind of phosphorylation is this?? ( I think I may have asked this before) and approximately how many molecules of ATP are produced.</p>
<p>Electron transport chain ? I forgot the name of the process, any help ?</p>
<p>how does the 2n zygote develop in human ? (look for the names of balls of cells)</p>
<p>Balls of cells what?? You mean mitosis in a gastrula?</p>
<p>I’ll wait for more answers to mine.</p>
<p>electron transport chain: oxidative phosphorylation as opposed to substrate-level in glycolysis and krebs cycle</p>
<p>The ETC is chemiosmotic phospholyration. And I believe the ETC produces 34 ATP molecules.</p>
<p>actually the answer i was looking for was oxidative phosphorylation/chemiosmosis where the ETC is just the name of the sets up the means for producing ATP by creating a proton gradient to power theenrgy to phosphorylate ADP to ATP</p>
<p>cleavage to morula to blastula, grastulation to grastrula and endoderm, ectoderm and mesoderm forms and then organogeneis producing the organs </p>
<p>what two colors of visible spectrum are most effective for photosynthesis? least?</p>
