Answer:
IF a high concentration of fertilizer is used, THEN orchid plants will grow best
Explanation:
The hypothesis in an experiment is the testable explanation given in support of an observer problem. It is a predictive statement that aims at proferring a possible solution to a problem or answer a question asked. The hypothesis must be able to be tested via experimentation as this is one important feature all hypotheses must possess. A hypothesis is usually written in an "IF, THEN" format.
In this question, an investigation is being carried out to know the effect of a certain amount of fertilizer on the growth of orchids in a greenhouse. A possible explanation/hypothesis will be:
IF a high concentration of fertilizer is used, THEN orchid plants will grow best.
This can be accepted or rejected depending on the outcome of the experiment.
Coal mining produces not only air pollution but solid waste; ash and flue - gas desulferization sludge ( look it up ), which contains toxic arsenic and radioactive uranium among other heavy metals. Water becomes polluted with these harmful substances through mountain top removal mining and so underwater creatures are poisoned and plants absorb deadly substances and die, which also contributes to the aquatic organisms death as the plants may have been a food source.
Although B and C both get his point across, C is the better option as it makes it easier to see. Graphs and infographics help researchers get points across colorfully.

Fission and fusion are nuclear reactions that produce energy, though they are not the same. Fission is the splitting of a heavy and unstable nucleus into two lighter nuclei. Fusion is the process where two light nuclei combine together releasing vast amounts of energy.
<span>Enzymes lower the activation rate of a reaction, thus lowering the energy needed to start a reaction.</span>
