<u>Answer</u>:
1. <em>The student could increase the number of loops of wire around the iron core. </em>Increasing the number of windings will increase the strength of the electromagnet also known as the magnetomotive force.
2. <em>The student could use a bigger battery so that the voltage is increased. </em>Thus, according to Ampere's Law, the magnetic field around the current-carrying wire will also increase as it is directly proportional to the current's strength.
In a hypotonic solution the water outside the cell is at a higher concentration than inside the cell. So gases, water etc. always want to move to lower concentration. So the water from outside the cell diffuses into the cell and makes it swell.

Try to stay true to who you are and find a good reason as to why you should be a great leader such as if you are in any AP classes or if you have demonstrated good leadership skills in the past. And if everything else fails people like food so you could bake/cook something cool that's has to do with science. Good luck!
