There are many types of monomeric molecules. To name a few, we can mention

    Monomer                                 Polymer            

• Monosaccharide       ⇒        Carbohydrates

• Fatty acid                   ⇒        Lipids

• Amino acid                ⇒         Proteins

• Nucleotide                 ⇒         Nucleic acids

Monomers are organic molecules of reduced molecular mass and  relatively simple, defined structure.  

Monomers are composed of carbon, oxygen, and hydrogen atoms, which establish covalent bonds.

In the case of lipids, fatty acids and glycerol are the composing monomers.

Lipids have a hydrophilic head composed of glycerol and hydrophobic tails composed of fatty acid chains.

The correct option is C. The lipids monomers are fatty acids and glycerol.

A car with a mass of 1,324 kilograms, traveling at a speed of 20 meters/second, crashes into a wall and stops. What is the kinetic energy after this perfectly inelastic collision?

Answers

The kinetic energy of a car with a mass of 1,324 kilograms, traveling at a speed of 20 meters seconds is 264800J.

How to calculate kinetic energy?

The kinetic energy of a moving car can be calculated using the following formula:

K.E = ½ × m × v²

Where;

K.E = kinetic energym = mass v = velocity

K.E = ½ × 1324 × 20²

K.E = 264800J

Answer:

When a red onion cell is placed in a 5% NaCl solution, the central vacuole will occupy

B) less of the cell than when it was in water

This is due to plasmolysis

Explanation:

What is plasmolysis?

Plasmolysis is the process in which there is a loss of water from cells when these are placed in a hypertonic solution. The protoplast and vacuole shrinks away from the cell wall.

What is a hypertonic solution?

Hypertonic solution is that which has higher concentration of solutes (low water concentration) as compared to inside the cell. As water moves from high conc. to low conc., it moves from inside the cell to outside. Thus, the vacuole pulls away from the cell when placed in a hypertonic solution (5% NaCl).
