<p>@likeastarr bacterias have no nucleus 
So it was either plant or animal and because you would see the plate forming + no centrioles, then it was a plant.</p>
<p>What did that question day? Because myosin is in constant change, the only one that isnt is the keratyn (sp?) filament, not sure if it was an answer</p>
<p>@ Balt, likeastarr, and Killi: Thanks for the quick responses - I didnât consider that the plant cell (which had a cell wall I think) would be the only one with the chloroplasts. 
Thatâs how out of it I was.</p>
<p>Was the high chloestrol question in M? I remember a weird question with random diseases that I didnât know but donât know if it was in M.</p>
<p>Think I got the insect/human curves AND 2 order of evolution diagrams ones wrong (whales are mammals? I need to think more)⊠missed others too. What is a predicted curve for a 750? Really leaning towards canceling atm.</p>
<p>There was a cell plate between the cells im sure of it 
and im pretty sure the atp helped the myosin contract or watever something like that xD</p>
<p>Wait, sorry, just want to clarify. about the movement of myosin, why isnât the answer âatp stimulates muscle contractionâ? doesnât that mean like the same thingâŠ? b/c atp makes the muscle contract or the myosin move.</p>
<p>No, cholesterol was in general questions. It was atherosclerosis.</p>
<p>artheclorisis blah something like that was the answer for the random disease question lol</p>
<p>it doesnât stimulate though⊠thats like a hormone stimulating the ovaries or something. The atp was directly involved in the contraction now i dont know what im talking about im braidn dead X|</p>
<p>thanks daesung! but iâm wondering why atp starting the muscle contraction isnât the same as making the myosin move⊠isnât muscle contraction myosin and actin like moving?</p>
<p>wow you answered my question without me asking it first⊠psychic LOL but thanks again for explaining. i see; it makes sense now.</p>
<p>Muscle question asked what ATP did: choices were âcontract a muscle,â or âchange in myosin head by changing to ADP and P.â I chose latter.</p>
<p>Cholestrol - how are you supposed to know this? Was it in Barronâs? Really shouldâve gotten bought it thenâŠ</p>
<p>Wait wait, cholesterol was in the E section, I took the M and I didnt have that. Plus I finished early so I checked those questions and there it was :P</p>
<p>@likeastarr it didnt say that, it said that it started muscle contraction. That would be calcium, not ATP. The only thing ATP does is provide energy so that the actin can move pushing the myosin which was more or less what the answer said</p>
<p>can someone explain how canceling your scores work? </p>
<p>do you get to see your score if you are not sure about canceling it?</p>
<p>[Sliding</a> filament model - Wikipedia, the free encyclopedia](<a href=âhttp://en.wikipedia.org/wiki/Sliding_filament_model]Slidingâ>Sliding filament theory - Wikipedia) lol i suck at explaining</p>
<p>JAKE,you can cancel by this wednesday. basically, if you donât think you did well, you can cancel scores. and wouldnât it be nice if we could see our scores first then cancel? unfortunately, you canât do that :(</p>
<p>thanks again daesung! :)</p>
<p>The question that asked how does the nerve cell send a signal to a muscle cell was it Chemical?</p>
<p>yes i believe itâs chemical. someone confirm please?

<p>Im guessing like 4-6 wrong for a minimum of 780 i might be wrong though </p>
<p>@BerBer yea i think itâs chemical I put synapse changed my answer at last second AGGHH D:</p>
<p>Yep, it was chemical.</p>
<p>what does canceling it do? does it make it not appear on your transcript?</p>
<p>i thought that you get your grade and then choose to either use it or not use it.</p>
<p>thanks guys and there you have your answer</p>
