the answers for the Kinetic Molecular Theory Quick Check are

1. the energy an object has because of its motion, 2. solid, liquid, gas, 3. the measure of the average kinetic energy of particles in an object due to motion, 4. solid, 5. helium

Explanation:

I promise these are right I just took the quick check

organisms that are both used in toothpaste as well as cause malaria are protista and monera.

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.
