I think you're referring to the "control".
Read more here: http://en.wikipedia.org/wiki/Scientific_control
The parts of an experiment that stay the same are known as the controls. The parts that change are called variables (hence they vary).
controlled group
the consents
it is called a constant, you got it right
idkmm
constants

All variables except for the independent and dependent variables should be kept the same. The other two will be changed by a fixed amount and by an unknown amount to be discovered during the experiment, respectively.
An experiment must have a control to show what would happen if no factors were changed.
Experts agree that in order for an experiment to be counted as 'good science' or a 'good experiment', they must contain three things:A controlData collected from the experiment, usually put into a table/chart/graphA conclusion drawn from the experiment~Information obtained from: http://www.chacha.com/question/what-are-least-three-things-you-should-be-careful-to-do-when-designing-an-experimentI do not claim ownership of the above website nor its trademarks and I do not claim ownership for the information.
use t he internet to find out its what i do :P loser lol
you must repeat and redo the experiment
the temperature must be kept constant
If they are supposed to affect the results in the experiment ie. they are what is being tested, they are the test variables. If they must be kept the same to ensure a fair test ie. the scientist is not testing with them, they are called control variables.

Yes, some people keep sea horses as pets. They are not easy animals to keep because they require good water quality, constant water flow and a special diet. If you want to keep seahorses as pets you should start by researching the care of other saltwater animals. The more you know about the species of animal you want to keep the better.

sodium must be kept under kerosene
What variables must be kept constant
a controlled experiment must have only one manipulated variable becuase if the experiment had multiple manipulated variables then it would not be a controlled experiment anymore it would be a manipulated Deseret experiment
The factor that can change in an experiment
you must repeat and redo the experiment
