The Acanthaster planci It is a kind of invasive starfish, which destroys corals: it has poisonous spines and feeds on coral polyps at the expense of the reef.
On the other hand, CO2 reacts with water, forming carbonic acid and reducing the available calcium carbonate, an essential element so that marine organisms, from clams to hedgehogs, can form their skeletons and shells.
Answer:
In these experiments the control group is compared with the comparison group.
The control group will sometime be in the presence of carbon dioxide, and will be controlled, where the analyst or researcher will take an expert position and then will compare it evolutionarily with the comparison group that the ideal would be that there is not ever a carbon dioxide
Explanation:
If we have two poison ivy research groups that are representative of the poison ivy that the researchers are looking to investigate the results will have much better credibility and will be more reliable.
On the other hand, the comparison of the two groups makes it possible to rigorously analyze whether or not poison ivy grows in the presence of this gas.
