• b) measuring temperature
• c) viewing tiny cells and organisms
• d) cleaning glassware

1. which career might someone in the biomedical/lab sciences pathway consider?

• a) chef
• b) laboratory technician
• c) pilot
• d) florist

1. what does \epidemiology\ focus on?

• a) the study of plants
• b) the study of weather
• c) the study of disease patterns in populations
• d) the study of stars

Explanation:

1. In a science lab, wearing safety goggles protects the eyes from chemical splashes, fumes, etc. Eating at the lab station can contaminate food or cause accidents. Touching chemicals with bare hands is dangerous as chemicals can be corrosive or toxic. Ignoring spills can lead to slips, falls, or further chemical reactions.
2. A microscope's main function is to magnify tiny objects like cells and organisms. Mixing chemicals is done with tools like beakers and stirrers. Measuring temperature uses thermometers. Cleaning glassware is done with brushes and cleaning solutions.
3. A laboratory technician works in a lab setting, which is relevant to the biomedical/lab sciences pathway. A chef works in a kitchen, a pilot in an aircraft, and a florist with flowers.
4. Epidemiology is the study of disease patterns (including occurrence, distribution, and control) in populations. The study of plants is botany, of weather is meteorology, and of stars is astronomy.

Answer:

1. B. Wearing safety goggles
2. C. Viewing tiny cells and organisms
3. B. Laboratory technician
4. C. The study of disease patterns in populations
