<span>2) Tool used. making sure whatever measurement the investigator is using should be valid and reliable. avoiding the possible results to become biased and unstable due to errors which should be avoided </span>
<span>3) Sampling method. obtain the samples which are appropriate and that would cover the entire participants studied- not a half but the entirely of what you want to study. entirely means as much as the possible sample covers. </span>
<span>4) Have some one else double check your findings. hope that helped</span>

Answer:
Answer is E. sets of identical proteins.
Explanation:
A virus is an example of microorganisms and it is considered to be the deadliest. It made up of capsid, which is the protein shell, that protects the RNA or DNA, which is its nucleic acid genome.
Microtubules are the microscopic structure, which are tubular in nature, found in the cytoplasm. They support and give shape to the cell.
The actin filaments serve as track for the movement of myosin , which is the motor protein. It also help in the formation of long filaments by joining many molecules together.
The spherical shell is the shape of the virus.
They are all built by proteins which are identical.
A plant cell has a rigid outer cell wall while an animal cell does not. This is what gives the animal cell the more fluid shape, and the plant cell a more typically square shape. I cant think of any more off the top of my head but there are some! I suggest you Google it, i had to do this a couple of weeks ago and there is a entire website with a list of the differences.
