    What is c in that context? I mean what does it represent?

    But if the smaller ball was hitting the floor, the bigger ball would move some more when the other ball hits the ground due to intertia right?

    Directly means there's no intermediate involved. Time, in this context, is not of the essence

    Actually it does. A robust growth of adjacent cells reduces the surface area...Think snout it.Smoking on the other hand...itLEADS to emphysema WGICH reduces the surface area

    What was B? Did it include that they both produce memory cells?

    Nope the picture was magnified by x10...that was A. Also guys lung cancer obviously reduces the SA to V ratio...it's for the same reason that larger animals have a lower ratio...cause they have more cells in their body

    Ib...25sin35=T 4b...count the squares and multiply it by the area on 1 small square 5c....it is losing power because the amplitude decreases. Intensity =(amplitude)^2 so you can determine the ratio from the graph

    Thanks but that doesn't answer my question...it actually makes it more confusing. In the potential divider question, the wire had some resistance too right? And to find the minimum potebtial difference between the two points, we took resistance of the potebtial divider as maximum and to find the...

    How come potential difference is highest when resistance is zero? Aren't potential difference and resistance directly proportional?

    And it was antigens, receptors and allows fat soluble substances to pass through.. Both glycoproteins and glycolipids act as both antigens and receptors

    It was D. The organism that everything else except plants was pointing toward. Decomposes break down nutriebts which plants take up so the arrow was pointing from that organism to the plants

    Oh wait they divided the speeds by acceleration! But why did they multiply by 2?

    It says in the ms that T= 2(1.7)-2(.7)..why? Those are the speeds not the time

    Why do we double the speeds then?

    Nope it is actually. Google it. And the highest magnification power if a light microscope is 400

    In 5(I) why do you multiply the speeds by 2 to get the respective times

    Did u talk to her about the plasmodium question? Or the lipid bilayer one?
