How can dichotomous keys be used to identify organisms?

• By measuring their size

• By observing their behavior

• By using distinctive characteristics

• By analyzing their DNA

What is the difference between a light microscope and an electron microscope?

• Light microscopes use light, while electron microscopes use electrons

• Light microscopes are smaller than electron microscopes

• Light microscopes have higher magnification than electron microscopes

• Light microscopes can see living cells, while electron microscopes cannot

What is the difference between magnification and resolution?

• Magnification is the size of an object, while resolution is the clarity of an image

• Magnification is the clarity of an image, while resolution is the size of an object

• Magnification and resolution are the same thing

• Magnification and resolution are not related to microscopy

What is biotechnology?

• The use of microorganisms in food production

• The study of fermentation

• The production of biological washing powder

What does biology study?

• Animal breeding, agriculture, and medicine

• Physics, chemistry, and geology
