Biology - December 2

<p>pretty sure nitrogen is correct.</p>

<p>what was the one with the cross like...what percent is BbTt or something like that??</p>

<p>idk i think it was either 1/4 or 1/8</p>

<p>It was 1/4.</p>

<p>no, you can put things more than once, meaning that it does not have to be compeition, it could be adaptation again.</p>

<p>yeah i was stuck between them but the way it was worded made competition make more sense...they have these adaptations to compete and such....</p>

<p>What did you guys get for the question that asked about the difference in vegetation growth between the two sides of rock, one side facing the east and one side facing the west? It specified that wind blew onto the west side. I narrowed it down between sparser vegetation on the west because the wind reduced moisture or denser because it increased moisture, but I felt the question could be contested.</p>

<p>vegetation is denser on the west because it increased moisture </p>

<p>u can see it here in california. if you drive over the sierras there is a huge forest on the western side but once u cross into reno there is nothing except desert :)</p>

<p>Yeah, that was what I thought initially, but I think it could be argued that the vegetation on the west side of the rock could be sparser. When I took AP biology last year, one of the labs in collegeboard's AP lab book involved a similar experiment, in which a pot of plant is exposed to breeze from a fan. The plant was suppose to grow bigger because photosynthesis increased as the fan brought in more CO2 and I suppose moisture as well. However, if the fan is placed too closely to the plant, the plant will close its stomata because the wind is too strong, thus leading to little to no growth. So, wouldn't the answer of whether the plant growth is sparser or denser be dependent on the intensity of the wind, which was not specified.</p>

<p>That cross one was 1/4. I did a little punnett square with the time I had left over.</p>

<p>the answer wasn't cloning- it was insemination-100% sure</p>

<p>W000TT...I so hope ur right crosscurrent....i put insemination...and i felt like a retard when others said it wasnt....</p>

<p>it is insemination....my dad works in a research lab lol.....I described him the scenario and asked him what it was and he said insemination right away lol- I then asked him if it's cloning and he said no- that to clone you have to clone OUTSIDE of the organism (in vitro) and then implant</p>

<p>cloning </p>

<p>The transplantation of a nucleus from a somatic cell into an ovum, which then develops into an embryo.</p>

<p>i found that in the online dictionary...isnt that basically what they did?</p>

<p>hahahaha tht is AWESOME.... </p>

<p>xD</p>

<p>dam blah...ur destroying my hopes and dreams man..</p>

<p>when do we find out our scores online?</p>

<p>ok what was the one with adding more stomata to the top off the leaf, does it improve respiration or whatever, or is there more evaporation.
and the practice books are too generous, about what does a 62 and a 65 raw score equate to approx.</p>

<p>stomata are openings in leaf-nothing to do with respiration- the correct answer was evaporation.</p>

<p>And I concede it was cloning</p>

<p>lol...i just want a 750</p>

<p>yes for evaporation and darn it...there goes the cloning / insemnation problem...</p>

<p>=/</p>

<p>lol blah...iono abt u i want a 800... =p</p>
