Virtual Population Dynamics Lab Assessment

This video tutorial is a virtual lab on population dynamics of two parium species. It involves setting up test tubes with individual and mixed cultures, observing and recording cell counts over 16 days. The tutorial guides students through the process of monitoring population density and graphing the data.

What is the main focus of the virtual population lab?

• Observing the population dynamics of parium species

• Analyzing the effects of temperature on bacteria

• Studying the growth of plant species

• Investigating the behavior of aquatic animals

How many test tubes are set up in the experiment?

• One

• Two

• Three

• Four

On Day Zero, how many parium Orelia cells are observed per milliliter in the first test tube?

• Zero

• One

• Two

• Three

What is the population density of parium cordatum on Day Zero in the second test tube?

• Three cells per milliliter

• Two cells per milliliter

• One cell per milliliter

• Four cells per milliliter

After two days, how many parium Orelia cells are observed per milliliter when grown alone?

• Five

• Seven

• Four

• Six

What is the population density of parium cordatum after two days when grown individually?

• Six cells per milliliter

• Four cells per milliliter

• Seven cells per milliliter

• Five cells per milliliter

What should students do after observing the population densities?

• Write a report

• Pause the video and count the cells

• Increase the temperature

• Change the test tube setup

What is the next step after determining the population of each species?

• Repeat the experiment

• Dispose of the test tubes

• Graph the data on graph paper

• Write a conclusion

On which day does the final observation occur?

• Day 10

• Day 12

• Day 14

• Day 16

What is the purpose of graphing the data collected in the lab?

• To predict future population trends

• To compare with other experiments

• To visualize the population growth over time

• To determine the accuracy of the experiment
