Answer:
Explanation:
No, the sorting process is not completed yet. The group that has two dragonflies in it should be sorted out independently and matched together to form a specie. The dichotomous key is used to identify items that belong to a particular specie.
The experimental designs are used in research to analyze and observe the changes to determine the result. In test tube, A (test) the lime water will turn milky, and test tube B represents the control.
<h3>What is an experimental design?</h3>
An experimental design is a setup that is used to observe and compare the test results of the control from the test group. Here, test tube A is the test and B is the control group.
From the experiment, the lime water in the test group will turn milky as there is cricket on the gauze of the tube. The cricket will release carbon dioxide as the result of cellular respiration and in return will react with lime water to produce a milky solution.
Test tube B, act as control as only lime water is present but the cricket is absent. It will be used to compare the results with the test group and will help in determining the role of carbon dioxide.
Therefore, the lime water will turn milky in test tube A.

An important buffer in the blood mixture of carbonic acid and bicarbonate ion.
Carbonic acid is a powerless inorganic acid, which is moreover considered a arrangement of carbon dioxide in water. Most of the carbonic acid at that point dissociates to bicarbonate and hydrogen particles.
