A model is a way of describing natural phenomenon that scientists uses to make various prediction.
Explanation:
A model is said to be good if it is both accurate as well as easy to understand which makes powerful as well as simple. Most of the models have certain approximation those are necessary for describing a model. As the observations are not exact so there may be little difference between what we observe. Models which are simple increase the accuracy and becomes superior in nature as well.
There are certain limitation of model such as , most of the model cannot explain the complex natural phenomena. For example when we want to measure distance it becomes difficult ,in the model we can represent earth as a sphere but it is difficult to show variation in distance as there are valleys mountain ranges and other features.
Using the cladogram about fish, the best description of the organism is it has jaws but no bones.
The correct option is (D).
<h3>What is a cladogram?</h3>
Cladograms are diagrams that depict the relationships between different taxonomic groups, or "clades."
Cladograms are made up of species that have similar derived traits.
Cladogram uses lines to make diagrams. And upper line contain the ancestor species.
Thus, option (D) has jaws, but not bones is correct.

Answer:
Tumor
Explanation:
When cell division does not occur in the usual pattern, a tumor results. This is also the major cause of cancer as there is usually the presence of tumors or cancerous cells
These cells multiply through cell division rapidly and abnormally thereby causing problems in the organisms as a result of them affecting and spreading to other parts of the body which are close to the tumor growths.
They copy the DNA from each cell and split into different cells to “reproduce” or make copies of each other.
The careful use of resources is called CONSERVATION. You can remember this because we are CONSERVING resources, which means to only use them when necessary.
Answer: conservation
