Researchers performing a well-designed experiment should base their conclusions on?
data from repeated trials of the experiment
What does a producer need for performing photosynthesis and what does photosynthesis produce?
they need sun, co2, oxygen, water... i think that's all.
What is scientific Dependent variable?
A dependent variable is a factor in an experiment that is influenced by another factor. An example might help to clarify. You are performing an experiment in which you are observing how sunlight affects plant height. Plant height is the dependent variable because it is dependent upon how much sunlight the plant receives. Sunlight is an example of an independent variable. It is not influenced by anything in this experiment, but may be changed to observe its effect on the dependent variable. It is possible to have more than one dependent variable in an experiment, but only one independent variable.
What is the importance of knowing the precautionary methods in performing or conducting an experiment inside a laboratory?
we need to identify the precautions method in performing an experiment inside the laboratory to determine do's and don'ts and to make our experiment satisfied. Knowing the laboratory set-up is important so that we can perform our experiments easy and enjoyable.
Is a plant part that cant do photosynthesis the roots?
Yes.Photosynthesis turns sunlight into food for the plant. Because the roots are underground, they don't get any sunlight. This prevents them from performing photosynthesis.
Within the framework of an experiment how do you describe the independent variable dependent variable and the controlled variables?
In an experiment, the independent variable is altered, and the effect observed is the dependent variable, or outcome. The controlled variable is intended to be kept the same throughout the experiment so that changes in it do not affect the results.
What would make the results of this experiment reliable?
performing the experiment multiple times
How will you ensure safety while performing experiments?
how will you ensure safety while performing experiment
How does oxygen get in the water?
It comes from an underwater plant performing photosynthesis
Researchers performing a well-designed experiment should base their conclusions on?
data from repeated trials of the experiment
How do you tell if a Mollie fish is a male or female?
By performing an experiment
What is another word for an observation made after performing an experiment?
results

is it true that an experiment is meant to prove that the hypothesis is correct?
An experiment is performed to generate more data. If the data proves to not support the hypothesis the experiment was still useful. You could reproduce your experiment to see if it is performing the way it should. After you have confirmed the experiment is performing correctly you then could devise another experiment to further test your hypothesis or accept the result and revise your hypothesis.
What is a sentence for the word cautiousness?
cautiousness is the best method for performing an experiment
When I test only one factor at a time?
You are performing a controlled experiment.
