Be sure to include how the ability to survive and reproduce impacts the process of natural selection. In your own words, what was the purpose of this lab? Please be sure to identify the test variable (independent variable) and the outcome variable (dependent variable) for this investigation. D. All laboratory-produced elements are unstable.

What caused the population of light-colored moths to decrease and the population of dark-colored moths to increase over time was because the dark-colored moths could camouflage themselves on the dark bark trees and the light-colored moths couldn't protect themselves from predators because they had no where to hid. Change the settings so that you still have brown fur mutations but this time remove the wolves and make the selection factor be food. Natural Selection Simulation at PHET. These statements reflect your predicted outcomes for the investigations. Access the simulation and explore the settings. What caused the tree bark to become darker is the time of the day the darker it is the darker the bark is.

The majority of the known elements have been discovered since 1990. b. In the lab simulation, which color peppered moth was able to have the highest rate of survival on the dark bark? Predict which color peppered moth would have a better chance of survival in your neighborhood? During the Industrial Revolution, explain what caused the population of light-colored peppered moths to decrease and the population of dark-colored peppered moths to increase over time. Be sure to list your hypothesis for each environment below. Run simulations in a variety of settings. You will investigate both environments. Natural selection lab report rabbits and deer. Test variable (independent variable): The test variable is the colored bark. Write the answer to your experimental question and then provide evidence for your answer from the simulation. Outcome variable (dependent variable): The outcome variable is the colored moths population. What are some VARIABLES that you have control over in the simulation?

REASONING (discuss WHY your evidence supports the claim, include biological principles as reasoning for outcome). Heritable genetic variation. Provide evidence from the simulation to support your conclusions. Using the simulation, determine the conditions when a long tail would be an adaptation. I believe that the dark-colored peppered moth would have a better chance of survival than the light-colored moths because there is mainly dark bark near my neighborhood instead of light-colored peppered moths. What is the difference between the arctic and equator environment? Experiment Challenge. Please write in complete sentences. Record your data for each trial of that environment in the data charts below. Recent flashcard sets. Hypothesis for the dark-colored bark: There will be an decrease in light-colored moths and an increase in dark-colored moths. Natural selection lab report rabbits and sheep. Jot down notes for each with what happened, you will need to synthesize this later. What are the three mutations you can add to your bunny population? Students also viewed.
The dark-colored peppered moth had a higher rate of survival than the light-colored moths. You will investigate two different versions of the tree environment as it changes over time: light-colored bark and dark-colored bark. Following the guidelines from the Experiment A, determine when long teeth provides an advantage to the bunny population. Rate of Survival for Dark-colored Peppered Moths. Reminder: The test variable is the item that is changing in this investigation. Potential for a species to increase in number. Factors that result in Evolution. Post-Industrial Revolution Bark (Dark-colored). What caused the tree bark to become darker? Natural Selection Lab Flashcards. CLAIM (answer): EVIDENCE (specific details and observations that support claim). Exploration of the Simulation.
