If you could repeat the experiment and make it better, what would you do differently and why? There are always ways that experiments can be improved. Now that you are a veteran of this experiment and have experience with the procedure, offer some advice to the next scientist about what you suggest and why. 7 Life Science
100 points gave me a good answer.
Answers
1. Increase sample size: By increasing the sample size, the statistical power of the experiment increases, which makes it easier to detect differences between groups or conditions.
2. Use a control group: A control group is essential to reduce the impact of confounding variables and to validate the experimental design. The control group should be identical to the experimental group, except for the manipulated variable.
3. Randomize the assignment of subjects: Randomization helps eliminate bias and ensures that differences between groups are due to the manipulated variable and not due to pre-existing differences between subjects.
4. Blind the experiment: Blinding reduces the impact of bias by preventing experimenters and subjects from knowing which group they are in. This can be achieved through single-blind or double-blind procedures.
5. Replicate the experiment: Replication is crucial to ensure the reliability of the results. Ideally, experiments should be replicated by different researchers in different labs.
6. Use appropriate statistical analysis: Choosing the right statistical analysis is important to ensure the validity of the results. Statistical tests should be chosen based on the type of data collected and the research question.
7. Document all procedures: Documenting all procedures, including the experimental design, data collection methods, and statistical analysis, is essential for transparency and reproducibility.
Hope this applies to your experiment in anyways best of luck

Answers
And im not sure about the rest :(
Storing hormones, smooth and cardiac muscles are the correct answers.
Storing hormones is not function of skeleton system. Skeleton system protects internal organs such as heart, kidney and lungs etc. It is also responsible for the movement of the muscles as well as produces blood cells because of the presence of bone marrow.
Smooth and cardiac muscles can contract without nervous system stimulation because they are involuntary Muscle which is beyond the control of the nervous system so we can conclude that storing hormones, smooth and cardiac muscles are the correct answers.

A forest fire destroys trees in a large area. The forest rangers use the burned area to study the effect of different types of grasses on soil erosion. They choose ten plots of ground that are the same size. Each of these plots receives the same amount of sun. Each of these plots also has the same kind of soil and the same slope. The rangers plant each with a different type of grass. Measurements of soil erosion are made every week for the entire summer. Which is NOT controlled in the experiment
A.the type of soil in the plots B.the size of the plots C.the amount of soil erosion D.the amount of sun the plots receive
Answers
Answer:
C.the amount of soil erosion
Forest rangers used this opportunity to study the effect of different types of grass on soil erosion, in this observation, the amount of soil erosion is not controlled, hence option C is correct.
What is uncontrolled observation in the experiment?A forest fire destroys the trees in larger areas after this forest rangers use this burned area to study the effect of different types of grasses on soil erosion.
Soil erosion states the depriving soil from the ground through natural calamities such as floods, and earthquakes, this is the measure cause of the soil erosion.
To study rangers plant each with a different type of grass and observe the effect of soil erosion every week for the entire summer.
Therefore, in option C the amount of soil erosion is correct.
