Exploring Key Concepts in AP Biology Labs

Mr. Anderson covers the first seven AP Biology labs, focusing on inquiry-based learning. Labs include artificial selection with Fast plants, Hardy-Weinberg equilibrium using beads and spreadsheets, DNA comparison for evolutionary relationships, diffusion and osmosis experiments, photosynthesis rate measurement, respiration analysis with respirometers, and cell division studies using onion roots and sordaria.

What is the primary focus of the new AP biology labs?

• Memorizing biological facts

• Following a set of instructions without deviation

• Designing and executing parts of experiments

• Listening to lectures about biology

What tool is used to pollinate plants in the artificial selection lab?

• Bee stick

• Butterfly net

• Water sprayer

• Plant clippers

What type of selection is demonstrated in the artificial selection lab?

• Random selection

• Stabilizing selection

• Disruptive selection

• Directional selection

What does Hardy-Weinberg equilibrium imply about allele frequencies?

• They are not important in genetic studies

• They will change every generation

• They decrease over time

• They remain constant under certain conditions

What is used to simulate mating in the Hardy-Weinberg bead lab?

• A cup with colored beads

• Live animals

• A virtual reality setup

• A computer model

What is the purpose of using phenolphthalein in the diffusion lab?

• To color the water

• To act as a pH indicator

• To decrease diffusion rate

• To increase the temperature

What does the respirometer measure in the respiration lab?

• The growth rate of peas

• The volume of water displaced

• The change in gas volume due to respiration

• The amount of light absorbed

Which gas is essential for the photosynthesis experiment discussed?

• Oxygen

• Nitrogen

• Carbon dioxide

• Hydrogen

What does crossing over during meiosis indicate about genetic material?

• It is exchanged between chromosomes

• It is duplicated

• It becomes less complex

• It remains unchanged

What phase do cells spend most of their time in, according to the mitosis data presented?

• Metaphase

• Interphase

• Anaphase

• Telophase
