<p>What phylum do sea urchins belong to?</p>
<p>echinoderms </p>
<p>and cancer</p>
<p>what is the function of antennae in the chloroplasts</p>
<p>^is that actually a sat subject test level question?</p>
<p>i hope not because i have never heard of those</p>
<p>Echinoderms- starfish and urchins. Higher on the evolutionary chain but show radial symmetry as they reach adulthood/maturity. Really all you need to know.</p>
<p>He means antennae pigments.</p>
<p>I forget if those are the ones that surround the p680/p700 systems or the actual ones on which they take place…</p>
<p>EDIT: They are the ones that pass the light energy onto chlorophyll a et al.</p>
<p>EDIT: Oh I need a question… What is biomagnification, also known as bioaccumulation?</p>
<p>question about cell membrane:</p>
<p>can water just diffuse through the membrane by osmosis? I thought that charged particles couldn’t pass the membrane by themselves?</p>
<p>THANKS!</p>
<p>Yes to both of those. Hydrogen need to go through protein channels I believe.</p>
<p>Does the light dependent reaction of photosynthesis produce ATP?</p>
<p>Yes, by photophosphorylation.</p>
<p>What is the starting sugar in the light independent reactions?</p>
<p>Yes, it does.</p>
<p>Can anyone give a brief description of photosynthesis and cell respiration ?</p>
<p>RuBP?</p>
<p>Where does the light independent reaction occur?</p>
<p>stroma</p>
<p>What makes nitrogen usable in the nitrogen cycle?</p>
<p>nitrogen-fixing bacteria in the root nodules of legumes</p>
<p>Where do glycolysis, kreb’s, and electron transport chain occur?</p>
<p>Glycolysis happens in cytoplasm and kreb’s and electron transport chain occur in the mitochondria. More specific, glycolysis happens in the matrix and electron transport chain occurs in the cristae. Am I correct ??</p>
<p>What is the raw material to start kreb’s cycle ?</p>
<p>i think its acetyl?</p>
<p>Pyruvate and Coenzyme A make Acetyl CoA which enters the Krebs Cycle.</p>
<p>Um, is there something wrong with this statement???</p>
<p>B is not the correct answer. You should have selected B .</p>
<p>I don’t trust Spark Notes for Bio. lol, I’ve been going to all my threads and saying that. ha.</p>
<p>no that answer’s right
lol i wouldn’t trust sparknotes either…</p>
<p>electron transport chain occurs in the inner membrane
glycolysis happens in the cytoplasm</p>
<p>What are the steps of transmission of an impulse to the brain?</p>
<p>dendrite–>cell body–>axon?
What are the requirements for Hardy-Weinberg equilibrium?</p>
<p>large popultaion
no migration
no mutations
random mating
no natural selection</p>
<p>biomagnification is like when organisms at higher trophic levels are going to accumulate larger amount of toxic wastes like the bald eagles and DDT that thins their shells</p>
<p>what type of muscle is the myocardial infrarction related to</p>
