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 angle formed of the rope with the surface = 40°
Force applied = 125Newtons
The displacement covered by the box =25metres
W= FDcos theta
[125×40×cos(40°) ] Joules
= [ (3125×0.76604444311)]Joules
= 2393.88888472 joules(ans)

Answer:
v = 10 [m/s]
Explanation:
The largest mass is that of 4 [kg], in this way the momentum can be calculated by means of the product of the mass by velocity.
where:
P = momentum [kg*m/s]
m = mass = 4 [kg]
v = velocity = 5 [m/s]
Now the momentum:
![P=4*5\\P=20[kg*m/s]](https://tex.z-dn.net/?f=P%3D4%2A5%5C%5CP%3D20%5Bkg%2Am%2Fs%5D)
This same momentum is equal for the other mass, in this way we can find the velocity.
![P=m*v\\20=2*v\\v=10[m/s]](https://tex.z-dn.net/?f=P%3Dm%2Av%5C%5C20%3D2%2Av%5C%5Cv%3D10%5Bm%2Fs%5D)
