The basic components (depedent and indepedent variables) are the plants and altitude while the confounding variable is the 20 story building. Confounding variables affect the experiement variable and are mainly outside of the researcher’s control in the experiment. Ray cannot change the building but this variable can affect the depedent and indepedent variables and cause distorted or spurious results.
Answer:
This question is asking to formulate a hypothesis for the experiment in the question. A hypothesis is:
IF natural compost is used instead of artificial fertilizer, THEN the tomato plants will grow faster and taller than when artificial fertilizer was used.
Explanation:
In an experiment, a hypothesis is formulated to provide a possible explanation or solution to an observed problem or question. The hypothesis must be testable or falsifiable via an experimentation.
In this experiment involving a biology student who is trying to find out if using natural compost will cause his tomato plants to grow faster and taller than his previously used artificial fertilizer. A possible hypothesis for this experiment goes thus:
IF natural compost is used instead of artificial fertilizer, THEN the tomato plants will grow faster and taller than when artificial fertilizer was used.
1. One of the main reasons for the extinction of the trees in the Eastern Island is the extinction or sudden demise of the birds that carried the seeds to different places. Some of the human activities would have also led to the process of extinction, like the trees were being cut to construct canoes and to use as tools in order to erect statues, and to burn them for warmth.
2. There was a need to farm the trees and manage them in a proper framework. For example, if one is having 100 trees, then one should use 33 and then plant 33 seeds, and should always keep 34 intact. One should have not used all the trees at once.
