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.
The correct answer is D. Characteristic of prokaryotic and eukaryotic organisms
Explanation:
Cells are the basic unit of life as all living organisms are made of one or more cells; additionally, all cells are surrounded by a membrane and contain substances and organelles that allow them to grow, obtain nutrients, reproduce and other basic functions for life. Additionally, as cells are the basic unit of life they are characteristic of both prokaryotic and eukaryotic organisms, although the structure in cells differs in both as in prokaryotic organisms there is no defined nucleus or bounded organelles. Thus, cells are characteristic of prokaryotic and eukaryotic organisms.
