The best answer would be letter D. C<span>ompare the average number of tomatoes that are produced by 10 tomato plants that are grown in clay soil to the average number of tomatoes that are produced by 10 tomato plants that are grown in sandy soil.
It would be best to grow more than one tomato plant in each soil to truly represent the tomato's growth in them. To average the number of tomatoes yielded by each soil sample would also allow a sample that is more representative of the tomato plants than merely comparing single tomato plants.

Answer:
The media describes Selective and Differential.
Explanation:
Given - MacConkey Agar contains crystal violet which binds to gram positive bacteria, preventing them from growing. The media turns yellow in response to the production of acid when lactose is fermented.
To find - Which two terms best describe this media ?
Proof -
The media describes Selective and Differential.
Reason -
MacConkey is a selective and differential media.
This media is used to selectively isolate gram-negative bacteria from other bacteria and differentiate them on the basis of lactose fermentation.
Lactose fermenters turn red or pink on MacConkey agar, and non-fermenters do not change color.
