4. describe the steps that happen during interphase.
5. describe the steps that happen during mitosis
6. what is it called when elements cross the cell membrane performs a high concentration to low?
diffusion
7. list all passive transport.
8. list all active transport.

4) There are three stages in interphase: G1, S and G2.

5) Stages of mitosis: prophase, metaphase, anaphase, telophase. 

I can only do the firs two but I hope this helps a bit!

the most common energy conversion is from kinetic energy to potential energy, and then from potential energy to kinetic energy.

later on comes the heat energy, mechanical energy, and other energy conversions.

this energy conversion is so common that we can find it in our day to day lives as well.

- one of the most common energy conversions involves the changing of potential energy to kinetic energy or kinetic energy to potential energy

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
