A. Use a scale to measure the mass of a cup of water. Leave the cup out for one day and measure the mass again.
Explanation:
Jenny can predict is evaporation occurs by using a weighing scale to measure that mass of a cup of water, then he leaves the cup out for one day and he measures the mass again.
- If the mass remains the same, then evaporation did not occur.
- If evaporation occurs, then the mass will be lesser after the second measurement.
- From this Jenny can infer the mass loss and made good deductions.
- Evaporation is a phase change in which liquid turns to vapor.

Answer: option D - After eating a large batch of salty popcorn, levels of salt in the urine increase
Explanation:
Homeostasis is the ability of a living organism to ADJUST its internal environment to maintain a stable equilibrium
FOR EXAMPLE: warm-blooded animals like humans allow blood vessels dilate during hot weather, and constrict during cold weather IN ORDER to maintain a constant body temperature.
Thus, after eating a large batch of salty popcorn, levels of salt in the urine increase due to the homeostatic mechanism of the ANTI-DIURETIC HORMONE stimulating reabsorbtion of water from urine, and excretion of excess salt.
