For each example, identify if the food contains mostly saturated or unsaturated fatty acids. Vegetable oil, which is a liquid at room temperature, is used in making cake batter.
Chocolate, which is solid at room temperature, is derived from a seed.
Butter, which is a solid at room temperature, is often used in cooking.
The oil inside flaxseed oil pills is liquid at room temperature.

1. Vegetable oil, which is a liquid at room temperature, is used in making cake batter. Unsaturated

2. Chocolate, which is solid at room temperature, is derived from a seed. Saturated

3. Butter, which is a solid at room temperature, is often used in cooking. Saturated

4. The oil inside flaxseed oil pills is liquid at room temperature. Unsaturated

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.

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.
