<span>factor is a variable
I would say its false, you can test 1 factor at a time</span>
Answer:
The temperature is kept at room temperature and mostly preferred to be constant, so that the temperature does't be a variable factor effecting the accuracy of experiment.
Temperature is kept constant to take it as a control factor, so that experimental results are not effected by such outside factors. Such control variables are important in experiments as they minimize the influences from outside.
Answer:
I'm pretty sure its the 1st one!
Explanation:
Dna are used to make chromosones, which are then uesd to make genes!
Hoped this helped!
Distillation is one of the processes that are used in the laboratory to remove impurities from substances. Distillation employs the differences in the boiling points of two liquids to separate them. The distillation apparatus must have an opening to the atmosphere at an end in order to avoid developing a dangerously high pressure within the system when heat is applied.<span />
