How will you set up a controlled experiment
satela [25.4K]
Research is necessary to gather data that is used to formulate a hypothesis and to create the experiment.

Identify a problem. The problem is the question you are trying to answer. Without a problem, there is no reason for experimentation.

Formulate a hypothesis. The hypothesis is a statement, based on your research, that is intended to provide a solution to the problem. The hypothesis is what you are trying to prove or disprove.

Conduct your experiment to prove the hypothesis. A controlled science experiment is setup to test whether a variable has a direct causal relationship on another.

Identify your independent and dependent variables. The independent variable is commonly known as the cause, while the dependent variable is the effect. For example, in the statement A causes B, A is the independent variable and B is the dependent. A controlled scientific experiment can only measure one variable at a time. If more than one variable is manipulated, it is impossible to say for certain which caused the end result and the experiment is invalidated.

Do not alter your hypothesis midway through the experiment. The setup of a controlled scientific experiment must be constant. You can not make changes once you have begun, even if the results you are getting do not seem to support your original hypothesis. When you change your hypothesis, you change the entire experiment and you must begin again.

Do not be upset if your results are not what you expect. Some of the greatest scientific advances have come from experiments that disproved the original hypothesis.

Start over again with a new hypothesis or find new variables to manipulate. Scientific advancement is a painstakingly slow process and scientists often spend years and even an entire lifetime working on the same problem.

Which virulence factor is a substance that directly damages cell membranes or enters cells and changes their function?
Vedmedyk [2.9K]

Exotoxin virulence factor is a substance that directly damages cell membranes or enters cells and changes their function.

Exotoxin- Exotoxins are a class of soluble proteins released by bacteria that enter host cells and catalyze the covalent alteration of one or more components of the host cell in order to change the physiology of the host cell. Exotoxins are produced by both Gram-positive and Gram-negative bacteria.

Bacteria- Microorganisms that are unicellular, capable of autonomous reproduction, and generally free-living are known as bacteria. In nature, bacteria are found everywhere. The foundation of all life on earth, they are architecturally basic but functionally sophisticated creatures.
