All stable atoms are made of
-positively charged, with the number of protons exceeding the number of electrons
-negatively charged, with the number of electrons exceeding the number of protons
-neutral, with the number of protons equaling the number of electrons
-neutral, with the number of protons equaling the number of electrons, which is equal to the number of neutron

1. D. Charge-to-mass ratio of electrons was the same, regardless of the gas used.  

2. Millikan

3. A. 1/840 the mass of a hydrogen atom

4. C.  Neutral, with the number of protons equaling the number of electrons

interphase   is the cell cycle stage in which the cell acquires nutrients, creates and uses proteins and other molecules and starts the process of cell division by replicating the dna. it is the longest stage in the eukaryote cell cycle.

the following   can go wrong during interphase:   a base pair could be mismatched during the duplication process causing a mutation.   correct answer: c
