question 14 (2 points)
two separate leaves are submerged in water. one leaf is placed on a window sill in the sunlight and the other is placed in a dark cabinet. you would expect the leaf in the dark cabinet to have more bubbles on its surface that the leaf in the sunlight.
true
false

Explanation:

First Question (Random Sampling Lab)

In random sampling, the "roll the dice" method is used to select samples randomly. The term "randomly" fits as the dice roll introduces randomness in choosing plots, while "purposefully" is non - random, "repeatedly" refers to doing something multiple times (not about selection method), and "cohesively" is about working together (not relevant here).

Leaves produce bubbles (oxygen) during photosynthesis, which requires sunlight. The leaf in sunlight will photosynthesize more and produce more bubbles. The leaf in the dark cabinet has no light for photosynthesis, so it will have fewer or no bubbles compared to the one in sunlight. So the statement is false.

Answer:

C. randomly
