How does temperature affect electrical resistance?

a. as temperature increases, electrical resistance decreases.

b. temperature and electrical resistance are unrelated.

c. as temperature increases to approximately water’s boiling point, electrical resistance decreases. beyond this, it increases.

d. as temperature falls, electrical resistance decreases.

Temperature affects metal in numerous ways. A higher temperature increases the electrical resistance of a metal, and a lower temperature reduces it. Heated metal undergoes thermal expansion and increases in volume. so the answer is C

c. the initial amount of money placed in the savings account

passive transport is a movement of biochemicals and other atomic or molecular substances across cell membranes without need of energy input. unlike active transport, it does not require an input of cellular energy because it is instead driven by the tendency of the system to grow in entropy.

so, according to what that says, i believe it's hypertonic and hypotonic.

good luck!
