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 ...

If 40.0 g of water at 70 degrees C is mixed with 40.0 g of ethanol at 10.0 degrees C, what is the final temperature of the mixture? How does one go about solving this problem? I found the specific heat of water and ethanol, but now what?

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!

Biology: Why do cells divide?
Which cells in the human body divide most frequently? Why is this? What activities or conditions spur cell division? What slows it down?

I believe that the "lines" that you would see (the cell wall and the plasma/cell membrane) would be thicker. They may even look like someone traced them with a pen, for example.

On average, what percentage of the cells in an onion root tip are in each of the different phases of the cell cycle? This question is for the purpose of checking lab data.

What is the difference between ATP synthetase and ATP synthase?

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 ...

Here's your answer: The pH scale ranges from 0 to 14. Pure water is 7. An acid has a pH value less than 7 and a base has a pH vale greater than 7.

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 ...

Monomer of the polymer nucleic acid (found in DNA and RNA, for example). Composed of a phosphate, a sugar, and a nitrogenous base.
