Achemistry student mixes 5 grams of sodium chloride (nacl) in 100 ml of water and stirs until all of the salt is dissolved. once dissolved, the student measures the electrical conductivity of the solution. an additional 5 grams of nacl is then dissolved in the solution. which statement most accurately describes how the additional five grams of salt will affect the electrical conductivity of the solution? a) the conductivity of the solution will increase because more ions are being added to the solution. b) the conductivity of the solution will decrease because salt is an insulator and more is being added. c) the conductivity of the solution will decrease because the concentration has changed--the solution is more dense. d) the conductivity of the solution will increase because additional electrical potential is being added to the solution.

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).

the design of a ski jumping suit involves a trade-off between giving the skiers lift to get higher jumps and ensuring the skier does not face a lot of drag before the jump itself. an expansive suit may to lift the skier higher, but at the same time, it will also increase the air resistance. higher air resistance as the skier goes down the slope limits the speed of the jump. a big suit also increases the risk of losing balance or control, especially if there's a strong gust of wind. while technologically enhanced suits a lot, clothing is not the only factor in a ski jumper’s success. gathering speed while skiing down the slope, ensuring good speed on the ramp, and maintaining good body posture and form in the air all contribute to a ski jumper's success.
