Atomic number, the number of a chemical element in the periodic system, whereby the elements are arranged in order of increasing number of protons in the nucleus. Accordingly, the number of protons, which is always equal to the number of electrons in the neutral atom, is also the atomic number.

It's 4. just took it, that's 1000% the right answer. that other person stinks for that non-answer, sorry. hope this helps. 
ps. if it's not obvious, you figure it out by taking the hypotenuse (120) and putting it over the height (30). 120/30 is pretty simple division.

Compare hypertonic, hypotonic, and isotonic solutions. When an environment is hypotonic, what happens to the cell?
algol13

When an environment is hypotonic, the cell has more solute so solvent move from outside the cell to inside causing the cell to swell.

WHAT IS TONICITY?

  • Tonicity is the ability of a solution to induce water loss or water gain in a cell. A solution can either be; hypertonic, hypotonic or isotonic

  • A hypertonic solution has more concentration of solute than its surroundings while a hypotonic solution has less concentration of solute compared to it's surroundings.

  • If a hypotonic solution has less solute, this means that it will have more solvent (water). Based on the principle of osmosis, water moves from a region of high concentration to region of low concentration.

Hence, water will move into a cell that is located in a hypotonic environment, causing it to swell.
