What is the scientific term for the things you make sure don't change during a experiment?
I assume the term for something that is not changed during an experiment is called, the control. Any changes observed in the experiment, can be compare to the control, which is still be in the original form before the experiment began.
What are the controlled parts of a controlled experiment?
the parts that you control
What is the part of an experiment to which you compare the results of the other tests?
The Control
When a chemist perform an experiment the quantity is being tested is the?
control
Why a controlled experiment might be impossible?
we don't have control over everything
What results from an experiment do you mistrust if your negative control is not as expected?
nothing
What is negative lactose fermentative organisms?
these are those bacteria which are not able to ferment lactose sugar hence are called non lactose fermenting or negative lactose fermenting organisms.
What's a negative control?
A negative control is a control group in an experiment where the variables are not expected to have an effect. It helps researchers to determine if any observed effects are due to the treatment being tested or other factors.
The positive control of the lactose operon in bacteria is what?
Catabolite repression is the positive control of the lactose operon in bacteria. Glucose is metabolized initially and when depleted, the lactose.
Does Morganella Morganii ferment lactose?
no, it shows negative for lactose fermentation on MacConkey's agar
What does controlled experiment mean in science terms?
All science experiments are performed in a controlled manner which means, there will be a positive control, a negative control and importantly the subject sample(s) who's behavior is not known. The experimental observation must be positive with the positive control sample and negative with the negative control sample, no matter whatever the condition is. Only in this set up the result of a subject (which is the actual unknown experimental sample) would be considered as a faithful result.Any fault or irregularities of the controls will destroy the authenticity of an experiment.
What is the controlled experiment in a science experiment?
The control in a science experiment is the same thing as a constant. It is something that you keep the same the entire experiment. For example if you were testing how various locations affect temperature your constants would be the thermometer you used and the time for measuring the temperature. If you don't have a constant than your experiment results won't be accurate.
Why are some organisms positive in the ONPG Test but negative when tested for the ability to metabolize lactose?
ONPG is for the detection of delayed lactose fermentation.
In a scientific experiment what is the definition of a variable?
Pretty much as it is in math, something that is undefined, but in Science it needs to be defined or the experiment cant continue. Your variables are basically what you measure, what you change and your control, both positive and negative (one with a 100% percent positive result and another with a 100% negative result)
Why is lactose fermentation common among enteric gram negative bacteria?
Probably because that is where the gram negative bacteria have found a food source. Lactose is not the perfered diet, but it works and they are most likely there because they can tolerate the environment, and survive (on lactose) when their #1 food source is not available.
Control of ball rebound experiment?
a control is something that stays the same in an experiment
What does control mean in an experiment?
control means to take conrol in a science experiment
