    Primitive organisms are the one who appeared early on earth and have simpler structures and body plans than the advanced organisms.
    Advanced organisms are complex and have acquired new features morphologically and anatomically by evolution from simpler organisms to better adapt the changing environmental conditions. However its not always true that advanced organisms have complex structures. For ex. Mammals have fewer teeth than primitive fishes.

    Density   (Specific Gravity) Relative density
    i. Mass per unit volume of a substance is called density. i. The ratio between density of a substance and density of water is called relative density.
    ii. Density = mass/volume ii. Relative density = Density of the substance/density of water at 40C
    iii. SI unit of density is Kg/m3
    CGS unit of density is g/cm3    		 iii. Units: Relative density has no units because it is the ratio between the similar physical quantities (density).

    A molecule of water will always have two hydrogen atoms and one oxygen atom, meaning that in a bottle of pure water the hydrogen to oxygen atom ratio will always be 2:1. This seems very logical to us today. But 300 years ago, scientists didn't understand compounds this way. However, in 1794, Joseph Proust published the Law of Constant Proportions, which says that a chemical molecule will always contains the same elements in the same proportion. There are two parts to the law of constant proportions: 1) there will always be the same elements that make up a compound, and 2) the mass of these compounds will always be in the same proportion. Elements in Compounds Pure water will always have hydrogen and oxygen atoms. It will never contain nitrogen, carbon, or phosphorus; it will only have hydrogen and oxygen atoms. Pure glucose will only contain carbon, hydrogen, and oxygen but no other elements. Pure ammonia will only contain nitrogen and hydrogen.
