Usually used with multiplication, creating an expanded algorithm is taking a formula and "drawing it out," or making it longer (and thus more simplified) by "un-distributing" it. For example: Expand (a+b)n. Answer: an + bn Why: In the problem, n should be ...

Make sure that all of the variables(sunlight, temperature, space, amount of liquid) are the same for both plants. The only thing that should be different is the type of liquid you give each plant. Good luck!

I think what you mean is the cell membrane/plasma membrane of a cell. If so, they are the same thing. Unlike the cell wall, the plasma membrane is flexible. In a plant cell, the plasma membrane pushes out against the cell wall to keep its shape. It is always immediately ...

During DNA replication, DNA Polymerase matches up the pairs of nitrogenous bases, prepared by the RNA primer (made by the enzyme RNA Primase)to create a new segment of DNA. They are matched to the bases on the parent strand. This occurs on both the leading strand and the ...
