Answer:
The correct answer is the second option - glycerol and fatty acids combine to form lipids.
Explanation:
Lipids are a polymer or macromolecule, and the smaller pieces, or monomers, that make up lipids are glycerol and fatty acids.
Option 1 is incorrect because nucleotides are the monomer for nucleic acids, not proteins.
Option 3 is incorrect because amino acids combine to form proteins, not nucleic acids.
Option 4 is incorrect because polysaccharides are polymers (the monomer for carbohydrates is monosaccharides).

Hypertonic. Cells in hypertonic solutions shrink because water moves out of the cell (from an area of higher to lower water concentration).
Isotonic solutions have equal concentration to a cell and hypotonic solutions have a lesser concentration than a cell, causing cells to swell as water enters.
Trichomes increase the chances of survival for plants living in areas with infrequent rainfall.
If a plant in a very rainy place had trichomes, it would probably adapt and remove them as time passed as they are unnecessary.
Answer:
Explanation:
metal can become magnetic if they have many spinning electron. When the majority of atoms spin in the same direction the strong magnetic field is produced the direction of electron spin determine the direction of magnetic field
