The following statements are real-world applications of life science:
1. Farmers study plant growth and are able to grow more fruits and vegetables.
2. Doctors can determine what is wrong with a patient and prescribe the right medicine.
4. Scientists can track animal movements and predict where they might be feeding.
5. Dentists recommend you brush and floss daily because bacteria cause tooth decay.
Statement 3, "Scientists study weather patterns to provide information about future weather," is more related to the field of meteorology rather than life science specifically.
