For Gradualism, changes in species is slow and gradual, occurring in small periodic changes in the gene pool, whereas for Punctuated Equilibrium, evolution occurs in spurts of relatively rapid change with long periods of non-change
The fly would no longer exist and all popuations will cease in their value
(a) solute = substance (solid or liquid) in lesser amount, which will [dis]solve into the solvent
(b) solvent = substance (liquid) in larger amount, which [dis]solves the solvent
it's dissolvability is called "solvency"
water is known as the universal solvent because it is abundant on Earth and has a high solvency
(c) solution = the combination of solvent + solute
depending on the saturation of solute within solvent, the solution may appear clear, like the solvent
**think of warm sugar-water (solution), when all the sugar (solute) dissolves into the water (solvent), the solute seems to have disappeared
Solution
Cut open an onion.
Use forceps to peel a thin layer of epidermis from the inside.
Lay the layer of epidermis on a microscope slide.
Add a drop of iodine solution to the layer.
Carefully place a coverslip over the layer.
