They are better because they are for comparative use for instance hair color to finger nails they both grow but onto separate parts of the body.

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
Answer and explanation;
-The hydrogen bonding in water is a a result of partial negative charge on the oxygen of one molecule which forms a hydrogen bond with the partial positive charge on the hydrogen of other molecules.
-When molecules of water are close to each other, their positive and negative regions are attracted to the oppositely-charged regions of nearby water molecules. This force of attraction is called a hydrogen bond. Each water molecule is hydrogen bonded to four others.
-This important property of hydrogen bond occurs in polar molecules such as water which contains weak, partial negative charge at one region of a molecule and also a partial positive charge elsewhere in the molecule.
Answer: D. Exponential
Explanation:
The exponential growth occurs when the resources are unlimited to the population of the species. The population grows rapidly at a constant rate. Thus the population size increases over concerned period of time. When the resources become limited the growth collapses this is called as logistic growth.
The exponential growth can be shown by the J-shaped curve.
