You want to test the effect of sucralose on the growth of a plant. Design a study using the steps of the scientific method. What
Julli [10]

Answer:

  • The independent variable is the concentration of sucralose present in the plant.
  • The dependent variable is the growth rate of the plant.

Explanation:

The study designed through the steps of the scientific method would be done as follows:

Observation: Sucrose is a very important molecule for the development and growth of plants, based on which sucralose, which is formed from sucrose, can be important for the same factors.

Question: Can sucralose influence plant growth as well as sucrose?

Hypothesis: Sucralose may establish some influence on plant growth.

Experimentation: Select a number of seeds inoculated with sucralose molecules and select the same number of seeds that were not inoculated with anything. Provide the same type of soil and environmental factors so that seeds can grow in the same way. Weekly evaluate the growth of the plants generated by each seed for a certain period of time. After this period of time, measure the weight of the plants and their roots. Place the plant and root to dry in an oven and measure the weight of the plant and root once again.

Analysis of results: compare the average weekly growth of plants generated by inoculated seeds, with plants generated from uninoculated seeds. Compare the average weight of plants generated by seed inoculated before and after kiln-dried. Compare the weight average between plant roots generated by inoculated seeds before and after kiln-dried. Assess whether there was a significant difference between the means.

Conclusion: Using the data presented in the evaluation of the experiment, state whether the hypothesis developed provides true or false information.

<u><em>Note: it is important that the seeds are from the same species of plant.</em></u>

When working with radioactive materials you must use radiation detection instruments. Which of the following instruments require
vampirchik [111]

Geiger-Muller tube is instruments requires you test three times the background of the work area.

<u>Explanation</u>:

These detectors are gas filled detectors and hence requires time for responding to the value. This time is taken because during this period it collects the electric charges and features of the electric circuit. It also gets stabilized during this period. This device has thumb rule i.e one must wait or hold for at the least 3 times the time constant before getting the precise and accurate reading. The time constant order is 10 seconds for the ionization chamber but for the Geiger counter it can vary from seconds to greater than 20 seconds
