Proteins, carbohydrates, nucleic acids, and lipids are the four major classes of biological macromolecules.
Macromolecules are made up of single units known as monomers that are joined by covalent bonds to form larger polymers.

Answer:
Explanation:
Simulation is imitating a process. It is doing exactly like a system will do. It can be used in technologies, education, health, training,
safety engineering. Simulation can be used when the original or exact system is not in place, or cannot be accessed.
A model is a process that helps to understands a system. A model is like an example to follow in achieving a result. A model may not be followed judiciously such that you may require an aspect of the model and then use but not necessarily all attributes while a simulation does exactly what the system does.
Answer:
Gene flow
Explanation:
Gene flow describes the process where genetic information migrates to another population, introducing new alleles into the gene pool and increasing the variation in that population.
Having physical barriers would prevent this exchange of information. For example, two populations separated by a mountain range or body of water would have far less chances to interact and exchange genetic material. This would make it difficult for gene flow to occur.
