AP Biology Labs - part 1

Mr. Anderson covers the first seven AP Biology labs, focusing on inquiry-based learning. He explains artificial selection with fast plants, Hardy-Weinberg equilibrium using beads and spreadsheets, DNA comparison with BLAST, diffusion and osmosis experiments, photosynthesis measurement with leaf chads, respiration rates using a respirometer, and cell division through mitosis and meiosis using onion root and sordaria.

What is the main focus of the first AP Biology lab on artificial selection?

• Studying the effects of temperature on plant growth

• Investigating the role of water in plant development

• Selecting traits to pass on to the next generation

• Measuring the impact of light on photosynthesis

In the Hardy-Weinberg equilibrium lab, what does the bead lab simulate?

• Natural selection

• Genetic drift

• Random mating

• Gene flow

What tool is used in the DNA comparison lab to analyze evolutionary relationships?

• PCR

• BLAST search

• Gel electrophoresis

• DNA sequencing

In the diffusion and osmosis lab, what happens to the agar cubes when placed in sodium hydroxide?

• They dissolve completely

• They turn blue

• They remain unchanged

• They change to a reddish color

What is the purpose of using a dialysis bag in the diffusion experiment?

• To measure the rate of photosynthesis

• To simulate a cell membrane

• To observe plant growth

• To test for glucose presence

In the photosynthesis lab, what causes the leaf chads to float?

• Absorption of water

• Release of oxygen bubbles

• Increase in temperature

• Addition of carbon dioxide

What is measured in the respiration lab using a respirometer?

• Temperature change

• Amount of carbon dioxide produced

• Rate of photosynthesis

• Volume of oxygen consumed

In the mitosis lab, which phase do cells spend most of their time in?

• Prophase

• Anaphase

• Interphase

• Metaphase

What organism is used in the meiosis lab to study crossing over?

• Onion root

• Sordaria fungus

• Germinating peas

• Fast plants

In the respiration lab, why does the respiration rate increase with temperature?

• Oxygen is less available

• Molecules move more quickly

• Carbon dioxide is more available

• Molecules move more slowly
