Singles Variables
a single variable
The methods section allows the experiment to be repeated by other scientists.
The main reason for conducting a science experiment is to test a hypothesis or answer a specific question through a systematic and controlled approach. It allows scientists to gather empirical evidence and draw objective conclusions about the natural world.
for a-plus biology answer to that question is: methods
Joseph Priestly
An experiment is based on controlling the environment, reactants, and conditions under which the procedures are carried out. If other externalities (variables) are not accounted for the experiment will be subject to sources of error. If a single variable is held constant than the test will be more accurate and replicable.
a conclusion
Scientist must isolate and clone diseased genes in order to study them. A clone of the gene allows scientist to find an exact cure.
a controlled experiment

A controlled experiment can be used to test almost anything. In a controlled experiment, the scientist (or experimenter) use a control group and an experimental group. The control group has nothing changed about it, and experiment group is changed based on the variable of the experiment. One of the most common uses of controlled experiments is the testing of new medications. In a medical study, a pharmaceutical company usually brings in a group of 100 people. Those people people are randomly assigned to two groups of 50. The experiment group is given the medication being tested, and the control group is given a placebo (a sugar pill). After several weeks, the experimenter can then see the side-effects of the medication, by comparing the differences between the experiment and control groups.
The manipulation of an independent variable during a scientific experiment allows a scientist to find a cause and effect relationship between variables. This is because the manipulation changes the results and measurements.
