Answer:
The correct answer is - observation.
Explanation:
Scientists like Si-Ling Chi, Aristotle, and Mary Anning developed various scientific processes and made discoveries that shaped the history of the world. such discoveries are discoveries related to silkworms and how to make cloth from their cocoons by Si-Ling Chi, developing the scientific method by Aristotle and Contribution to the field of paleontology greatly by Mary Anning.
All these scientists had a different type of skill and ability and one of the skills they had a strong power of observing the things or phenomenon work and many more other aspects of the scientific process.
The function of the lens is that it allows light rays to focus into the retina. They are composed of fluids that contains lots of nutrients for the lens to gain from it and cleanses dirt if it comes in contact the eye. Overtime, this lens, will slowly degrade as its fluid will start to lose.
It is best to use regular light microscopes to observe that.
For simple structures, onion cells doesn't require a very large magnification. Magnifications for such as 100X or 150X is already enough to determine the different structures of onion cells such as cell walls or cytoplasm.
It is not very suitable to use a electron microscope especially as high school or college students, as electronic microscopes can be really expensive, usually only top universities have them. Also, it is quite complicated to control the microscope comparing to the common light microscope that we can easily find in many school laboratories. They're easy to function and they're a lot cheaper.
So, it's best advised to use a light microscope, unless if you're really into studying very detailed structures and you're experienced in doing these sorts of things, then you should use a electron microscope.
