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>

Answer:

Answers may vary. Here’s one possible answer:

The scientific method design will consist of these steps:

Make observations: A sugar substitute was detected in the environment where the plant lives. Earlier studies have shown that the sugar substitute affects energy production in plants.

Ask questions: Would plants grow if the water contained the sugar substitute?

Construct a hypothesis and make predictions: Plants that are given plain water will grow taller than plants given water containing the sugar substitute.

Test the hypothesis: In the experiment, the independent variable will be the type of water the plants receive. The dependent variable will be the growth of the plant. Use two identical plants for the experiment. Give one plant water with the sugar substitute, and give the other plant plain water. Keep the plants in identical environments. Give each plant the same amount of water every day. Measure their growth over the course of three months.

Analyze the results and make a conclusion: After three months, analyze the data to see whether one plant grew taller than the other.

Test/Modify: If the hypothesis is proven right, repeat the experiment. If not, modify the hypothesis and design a new experiment.

Both the nervous and endocrine systems control body functions. How are they similar and dissimilar in the way they work, types o
polet [3.4K]

Answer:

Similarity

Both nervous and endocrine system are similar in a way that they perform the regulatory function in the body and act as regulator in various body functions.

Difference

1. nervous  system uses  electrical impulses (neural)for signaling while endocrine system  uses chemical signals called hormones, which travel through the bloodstream and control the actions of cells and organs.

2. The nervous system can respond quickly to stimuli, through the use of action potentials and neurotransmitters. Responses to nervous system stimulation are typically quick but short lived. The endocrine system responds to stimulation by secreting hormones into the circulatory system that travel to the target tissue.

Amoebas, paramecia, and euglenas can all reproduce by fission. <br> a. True<br> b. False
Sever21 [200]
The answer is True.

Amoebas, Paramecia, and Euglenas are all types of protist that can reproduce asexually through binary fission. This is the most common form of reproduction in prokaryotes. The reproduction occurs in a single cell. The cell divides into two nearly equal sized along with its genetic material.
