What else can I help you with?
What was the independent variable in sir Alexander flemings experiment on penicillium What was the dependent?
In Alexander Fleming's experiment, the independent variable was the presence or absence of penicillium mold, which he introduced to the culture plates. The dependent variable was the growth or inhibition of bacterial colonies in the vicinity of the mold.
In a experiment the group that is exposed to the variable to the tested is called the what?
That is the Control group.
What are three components of an experiment?
The three components of an experiment are the independent variable (the variable that is being manipulated), the dependent variable (the variable that is being measured), and the control group (the group that does not receive the treatment being tested).
Identify the variables that you need to control and the variable that you will change?
To conduct a controlled experiment, you need to control all variables except the one you are changing. The variable you change is called the independent variable, and the variable you measure in response is the dependent variable. Control variables are those that could potentially affect the outcome of the experiment but are kept constant to isolate the effect of the independent variable.
What is the part of an experiment that you keep the same?
The part of an experiment that you keep the same is called the "control variable." This variable is used as a baseline for comparison to measure the effect of changing other variables. Keeping the control variable constant helps to ensure that any changes observed in the experiment are a result of the manipulated variable and not other factors.
What is the difference of a dependent variable and an independent variable?
An independent variable is when you do not control what happens In an experiment,however; a dependent variable is when you actually control the experiment,
What is the difference of independent variable and a dependent variable?
An independent variable is when you do not control what happens In an experiment,however; a dependent variable is when you actually control the experiment,
What is the difference between control and controlled variable?
control is when nothing is done to the experiment and controlled variable is that you have control over the experiment.
What is the independent variable for growing mold on food?
The answer to your question depends on the experiment you are doing, but time would probably be the independent variable (and the amount of mold would be the dependent variable).
What is the control group and what is it used for?
The control is the part of the experiment where it remains constant, and never changes. The control is used so the changing variable in the experiment can be reflected off of the control, so thereby comparing the changing variable with the control (the variable that does not change) in the experiment. Without the control, the experiment is a waste.
What is a the difference between a control and a variable?
A control is the standard to which an outcome of an experiment is compared, but a variable is something in an experiment that can change.
Variable that doesn't change in an experiment?
The variable in an experiment that remains the same is known as the control.
What is an experiment that does not contain a variable?
The control does not contain a variable!:)
What variable is an experiment control?
The variable that stays the same
What is the difference between an experimental variable and a control variable?
In a controlled experiment, the control variable remains constant while the experimental variable changes with each trial of the experiment.
What is the difference between experimental variable and a control variable?
In a controlled experiment, the control variable remains constant while the experimental variable changes with each trial of the experiment.
What is the difference between an experimentation variable and a control variable?
In a controlled experiment, the control variable remains constant while the experimental variable changes with each trial of the experiment.
