The four classes of polymers are:
1. Nucleic acids. Examples are DNA and RNA
2. Protein. Examples are enzymes and hemoglobin
3. Carbohydrates. Examples as starch and glycogen
4. Lipids. Examples are triglycerides and phospholipids
The building blocks of nucleic acids are called bases and there are four types known as Guanine, Adenine, Thymine and Cytosine.
The building blocks of carbohydrates are glucose molecules.
The building blocks of protein are amino acids.
The building blocks of lipids are a combination of fatty acids and glycerol.
Answer:
the ratio of the smallest division of main scale to the number of divisions of the vernier scale.
Explanation:
difference between the value of one main scale division and one vernier scale division
F=K*X,
F=M*a
M*a=K*X
2.5*9.81=K*0.0276
24.525=K*0.0276
24.525/0.0276=K
K= 888.6 N/m ---- force constant
assuming 2.5 refers to the new extension, just divide F/ 0.025
to get
981N/m
