The correct answer is option D. She should place one flower in a similar container, but not pump carbon dioxide into it. She should also give each plant the same amount of water.
In the experiment, a control should be present to compare the effect of the variable in the experiment. In the control sample, all the parameters except the variable should be same as the experimental group. In this way, the comparison of the effect of variable can be easily done in an experiment.
In this case, the variable is amount of carbon dioxide the plant receives. So, Stella should include a control group by placing the plant in the same container and leave it on atmospheric carbon dioxide supply, no extra carbon dioxide should be pumped into it. Also, the amount of water she give to each plant should be the same to maintain the water level as constant.
Answer;
-Thoracic
Thoracic because of the rib facet on the body and elongated spinous process
Explanation;
-Thoracic Vertebrae functions to hold the rib cage and protect the heart and lungs. The twelve thoracic vertebrae are numbered T1 to T12. The range of motion in the thoracic spine is limited.
-Distinguishing features of the thoracic vertebrae include; the presence of facets on the sides of the bodies for articulation with the heads of the ribs, and facets on the transverse processes of all, except the 11th and 12th vertebrae, for articulation with the tubercles of the ribs.
The answer would be a multi-cellular organism. This is because multi-cellular organism's body parts depend on only themselves, so they do not rely on each other for survival.
