Both physical and chemical
D)By increasing or decreasing the size of systems that are difficult to study we make it easier for students to see how they work and therefore make it easier for them to learn.
Explanation:
Scientific models makes it easier to teach students about systems because their sizes can be adjusted and this makes it easier for students to see how they work.
A model is a simplification of the real work. It takes a part of the real world and studies it.
Models are highly desired in teaching and understanding very complex systems.
- Since a tutor owns the control of the model, they can make adjustments on them to a scale that is convenient to work with.
- Also, a part of a system can be studied one at a time making it simple for students to comprehend.

Answer:
1. Vegetable oil, which is a liquid at room temperature, is used in making cake batter. <u>Unsaturated</u>
2. Chocolate, which is solid at room temperature, is derived from a seed. <u>Saturated</u>
3. Butter<u>,</u> which is a solid at room temperature, is often used in cooking. <u>Saturated</u>
4. The oil inside flaxseed oil pills is liquid at room temperature. <u>Unsaturated</u>
Explanation:
Saturated fats are those kinds of fat that do not have a double bond between their carbon atoms when represented structurally. At room temperature, they tend to assume the solid-state, and they are mostly obtained from animal sources. Unsaturated fats do have a minimum of one double bond between their carbon atoms and tend to assume the liquid phase. They are mostly obtained from plant sources.<em> </em>
1. Vegetable oil is obtained from a plant source and is, therefore, unsaturated fat.
2. Chocolate even though it comes from cocoa is solid at room temperature and is mostly comprised of saturated fat.
3. Butter a solid at room temperature is mostly made up of saturated fat and is sourced from animals.
4. Flaxseed oil obtained from a plant source is mostly unsaturated fat.
