Three examples that biology can help in our everyday lives:
1. When you are faced with an animal, for example, a snake, you will know how to deal with it. You will examine what species that the snake belongs to and you will be able to identify its weaknesses.
2. When you are lost in a forest and that everything around you are plants and trees, you will know what kind of plant is edible or not and you can survive in the forest by utilizing what is available at your disposal.
3. You would also know what kind of food is good or not for the system. You will be able to analyze the kind of nutrient of the food you eat and how it will interact with your body system.
