Answer:
Katherine wants to investigate if the time of day a plant is watered affects the growth of the plant right? If she waters the plants at the same time she is not doing the experiment. Although she has the same type of plants, the same amount of water, same location and same amount of sunlight for each of them, how is she going to find out what she needs to if she doesn’t water them at different times?

Katherine is only investigating the one plant in the one location. In order to properly investigate if the time of day a plant is watered affects the growth of the plant, then she needs multiple types of plants in multiple locations. Additionally she should label each location, a, b, c etc. Then she needs water each location of plants at a different time of day, and record the growths of each location.

SashulF [63]
Natural selection is the process where organisms that are best suited to their environment survive and pass on their genetic traits in increasing number to successive generations. At the same time, organisms that are less adapted fail to survive or multiply at a lower rate, and tend to be eliminated from the ecosystem.
