Food preparation is the process that involves planning and preparing of meals. The food prep (preparation) list is a sheet that contains information of ingredients and the amount of each of the ingredients required when preparing a particular dish. The food prep list is part of a recipe which makes the kitchen much more organized and prevents wastage and excessive use of ingredients.
Answer:
You did not write the concept, so i will try to answer in a general way.
Why sometimes we really need to model concepts?
Well, sometimes the things are really complicated, or we just do not have the knowledge or tools to fully understand them.
Here is where the models came to be handy, we can somewhat "simplify" the things, and explain them with models.
For example, the movement of a particle as the wind pushes it can be really complex, so this can only be explained with a model.
Now, once we have a model (supported by theory and experiments) we can start to investigating furthermore in the given subject.
So for example, we could model how a given therapy acts on a given disease, and with that model, we could extrapolate the effects of the therapy in a similar disease (for example, testing how radiotherapy acts on a given tumor in some organ, can give information on how the same therapy can act on other types of tumors)
Concluding, models simplify some concepts, which allow us to understand them and work better with them
B <span>What is the effect of crop selection for pest resistance on the distribution of leaf size in a population of plants?

Plasma membrane. controls in/out of cell.
chromosomes. DNA, instructions for protein synthesis.
ribosomes. manufacture proteins.
metabolic enzymes. building and breaking down molecules.
cytoskeleton. skeleton of cell that proteins can move by.
Lipids perform all of these functions except are NOT responsible for creating proteins. The process of protein synthesis, which would involve transcription and translation does not involve lipid molecules being major players in the process.
