The independent variable is the chemicals and the dependent variable is the plant growth.

Answer: c. Transition Reaction
Explanation:
During the transition reaction, Acetyl-CoA is formed and connects the first stage of glycolysis with the Krebs Cycle (Citric Acid Cycle). In the presence of oxygen, pyruvate enters the mitochondria and is oxidized to form a compound of 2 carbon, acetate, with energy and CO2 release. During this process, the acetate binds to a coenzyme(coenzyme A (CoA)) - forming the acetyl-coenzyme A.
The 3 steps:
1. pyruvate is oxidized and forms acetate with liberation of CO2;
2. the energy released in the oxidation of pyruvate is stored in the reduction reaction of NAD+ to NADH + H+
3. The acetate molecule combines with coenzyme A to form acetyl-coenzyme A.
Answer: A. Plant
Explanation:
Plants have some of the most of complex cells of living organisms because they have different roles and structures to enable the plant to survive.
These include cells like the Parenchyma, Collenchyma, Sclerenchyma, Xylem and Phloem cells. Xylem cells for instance are complex cells located within the vascular tissues of plants and help transport water and minerals to the rest of the plant from the roots. Xylem cells look long and tracheal which is to enable them carry out the aforementioned roles.
<span>Of the 118 elements that have been discovered, 90 of them indisputably occur in nature. There is disagreement over whether four more or eight more occur naturally as a result of radioactive decay of other natural elements. The answer is, therefore, 94 or 98.</span>
