A: the sun

Question: Read the passage below and choose the right answer to the following question (choices are decrease them or increase them ): As humidity increases, the water potential gradient across the inside and outside the leaf become more equal, and so the rate of transpiration decreases. Ian wants the transpiration rate to rise in his leaves, so he will do what with the humidity levels decrease them or increase them?
Answer: decrease them

*Question*
Read the passage below and choose the right answer to the following question (choices are increased or decreased ): A: As the car approaches the radar gun, the reflected microwaves get bunched up in front of the car. Therefore, the waves the receiver detects have a higher frequency than they would if they were being reflected from a stationary object. The faster the car is moving, the greater the increase in the frequency of the waves. The cop shot the radar gun at the super fast car, which increased or decreased the waves?
**Answer**
increased

(Q).
Read the passage below and choose the right answer to the following question (choices are rise higher or sink lower ): Warm air is less dense than cool air, so it rises higher in the troposphere. If Jim lowers the temperature of the air inside his balloon, will his balloon rise higher into the air or sink towards the ground rise higher or sink lower?
(A).
sink lower
