Answer:
The density of the substance is 3.9 grams per cubic centimeter.
Explanation:
Given mass=27.3 grams
volume=7 cubic centimeter
We need to find the density.
Density of a substance can be calculated by dividing mass of substance by volume of a substance


Hence Density of the substance is
.
energy is completely different from energy conservation. Energy conservation means saving energy through such things as insulating your home or using public transportation; generally it saves you money and helps the planet. The conservation of energy has nothing to do with saving energy: it's all about where energy
The unique identity of amino acid is that each amino acid is bonded to each central atom known as R-group.
Explanation:
Amino acids are nothing but a basic structure which has a central atom called the "alpha carbon atom". This
carbon atom is bonded to an "amino group" (
), a "carboxyl group" (COOH) or a "hydrogen atom".
There are totally "20 types" of amino acids having a central atom bonded from the R-group. For example: When the R-group is hydrogen, then the amino acid is named glycine. Similarly, if it is attached to methyl group, then the amino acid is alanine. This makes the amino acids unique.
