Answer:
mass- the amount of matter in an object
balance- tool used to measure mass
scale- a tool used to measure weight
weight- the downward pull on an object due to gravity
Centre of Mass then axis of rotation and then moment of inertia. This was the toughest question for your level... happy to help ^_^. It was purely experimental question.
One must have at least two visual pigments to distinguish between wavelengths independent of light intensity.
A substance that converts light energy into electrical potentials is called a visual pigment.
The basic structure of pigment consists of the chromophore, a colored molecule, and a protein called rhodopsin.
There are three types of visual pigments: Scotopsin, rhodopsins, and photopsin.
Scotopsin pigments are associated with vision and operate in less bright light while photopsin operates in a brighter light.
However, visual pigments are very significant substances as they are associated with vision and play a vital role in detecting light.
