The experiments demonstrate the movement of pollutants through the ground water.
The sand and gravel make up the ground the water represents the ground water. The food coloring represents the pollutants.
Answer:
The answer is D) All four species may be related, but each would have a unique scientific name using binomial nomenclature.
Explanation:
(Original chart was not attached, make sure to include it in your questions)
Using the process of elimination, you can eliminate options A and C. Option A is incorrect because there is a visible relationship between each of the species, hence the phylogenetic tree, and the branches connecting each one. Option C is incorrect mainly because we cannot determine if W is extinct based on the chart.
Now as you're left with options B and D, you can knock B off the map because X and Y may have the same species, but either way this cannot be established because we are unknown of each organism and their species.
<em>The surest answer will be D as they are evidently all related, and each would have a unique scientific name due to binomial nomenclature. </em>
