<p>no L4 was the control</p>
<p>there was another question about the Independent Variable</p>
<p>ya the independent was the gene which he added to the plants. I forgot what it was called had a long name</p>
<p>^I second that answer.</p>
<p>^ I third it, lol.
L4 was control.</p>
<p>Oh yea the idependent variable was the tomato.
Height changed.
Genes were only added to a select few.
The last one was also dependent (can’t remember.
Thus the only item that remained the same was the tomato because it was used in all experiments.</p>
<p>no the tomato plant is not a variable it was the gene, variable is something that is different ie different gene in each plant</p>
<p>Gene’s weren’t added to every plant. The tomato plant was independent because it was constantly used.</p>
<p>that is why it is a variable in no way does the tomato plant vary from plant to plant because it is the same plant</p>
<p>I’m not talking about the L4 ones, I was talking about the tomato one.</p>
<p>i could be wrong but isn’t the independant variable the thing that changes the dependant variable? i think some ppl seem to be mixing up independant variable and controlled variable. a controlled variable is something that doesn’t change</p>
<p>yes you are correct. Thus, the gene added to the tomato plants is the independent variable and it controls the dependent variable, the plant height</p>
<p>i randomly put (F) for the very last question on the science section…
is this correct??</p>
<p>Are you guys sure it’s conduction? I’m pretty sure it’s Radiation only.
I just learned about conduction, radiation, and convection from AP Bio like Last week.
Conduction occurs when heat is transferred when something hot touches something cold.
Radiation occurs naturally and hot goes to cold.
Convection is when wind touches something hot, moving heat away.</p>
<p>Convection was definitely wrong.</p>
<p>It was only conduction. Conduction is the movement of heat from hot to cold where the particles are touching, such as in the insulator. Radiation is the transfer of heat through empty space, which was not what was being asked.</p>
<p>Ah. Got it. Alright, thanks for clearing that up.</p>
<p>twaan, people dont usually remember the letter answer of the questions, usually the answer itself. so if you remember the question at all, it would be helpful.</p>
<p>i filled random bubbles for the last 5 questions. couldn’t finish! :(</p>
<p>soccerrrgal - me too! I don’t no what it was about this science test but i def didn’t finish either. I just chose to fill in D for about all of the last 6. I hope I got at least two of these right!</p>
