Question

This hands-on laboratory exercise is a highly simplified model that attempts to simulate evolution by means of natural selection. Predators will act as agents of selection on their prey, a species whose members vary in color. We will assume that color is an inherited trait. Small squares of paper will represent the prey, which will be spread out of a piece of printed colored fabric that will serve as the habitat. The predators (you) will prey upon the population, with the surviving members reproducing and passing along the genes for color.

Answer 1

I don't want a answer this is a lab asgmt I just want direction where I can complete work

Answer 2

biology eh ....

Answer 3

If you use the flvs link you would see everything but I'm try to figure this on the web maybe a link to a website or somthing

Answer 4

it looks like its trying to present the idea that prey that matches its habitat are harder to spot; and therefore get to live long enough to pass on their genes. If we assume color is inheritied then evolution would weed out the colors of the population that dont fit in with the environment.

Answer 5

the link to the website is useless; it monitors cookies and since i never logged into it to view that link I dont have to proper online credentials to view it.

Answer 8

That link is not authorized, it gives anyone but you this information:

The system is unable to access the cookie that was assigned to your computer upon login. The most likely cause of this problem is an improper access to the course via a bookmark, browser window that was left open, or an improper exit from the system.

To resolve the problem you will need to:

Log into your course
Delete your browser cookies
Click the "Logoff" button
Reboot your computer
Sign back into your account
Make sure you properly logoff and close your browser window each time you exit the system
If you need assistance resolving this problem please follow the steps below:

Click on the "Technical Support" link within your course.
Click the "Educator Help Desk" sublink, located just below the "Technical Support" button you just clicked.
Select that the "Nature of your problem" is with the "Educator System". This will route the request to our team.
In the problem description field, provide a brief description of the problem you are experiencing. In this case, something along the lines of "When I click on Lessons I get a cookie error" will be more than sufficient.
When you click the "Submit" button this will send your problem description to our team along with your account information and some information about the browser you are using. We will then reset your account as quickly as possible and provide you with the appropriate steps to reset your browser on your computer.

Answer 9

If it were you what steps would you take to completet this lab asgmt

Answer 10

dunno, Im not able to see the instructions to the lab. You might want to post the instructions as a whole so people can generate ideas.

Answer 11

Ok

Answer 12

This hands-on laboratory exercise is a highly simplified model that attempts to simulate evolution by means of natural selection. Predators will act as agents of selection on their prey, a species whose members vary in color. We will assume that color is an inherited trait. Small squares of paper will represent the prey, which will be spread out of a piece of printed colored fabric that will serve as the habitat. The predators (you) will prey upon the population, with the surviving members reproducing and passing along the genes for color.

Problem:

How does a population change as a result of natural selection?

Materials:

5 different colors of paper cut into 1 cm × 1 cm squares (at least 100 squares of each color)
Multicolored fabric or newspaper, approximately 1 meter × 1 meter
1 or 2 partners (friends or family)
Procedure:

The prey will be represented by the small 1 cm × 1 cm squares of paper and the habitat is represented by the 1 meter × 1 meter piece of fabric. Hypothesize which color prey you think is most likely to be captured by the predator and which color prey is most likely to survive, and then record your hypothesis. Be sure that your hypothesis includes explanations for your predictions.
Have the two partners (prey) stand with their backs to the habitat while you scatter 20 squares of each color randomly on the fabric. Try to achieve a uniform distribution, and be sure to separate any that are clumped together.
Have the partner(s) randomly pick up the prey as fast as they can. Have them stop when they have collected a total of 75 prey, leaving the other 25 remaining in the habitat.
Count the number of survivors of each color. Each surviving prey has three offspring of the same color, bringing the total population back up to 100. Record the number of each color in the next generation in your data table.
Count out the correct number of each colored prey and scatter them on the fabric. Repeat the process two more times, for a total of three generations.
Data and Observations:

Create a data table containing a tally of the number of each color of prey in each generation:

Color 1._________ 2._________ 3._________ 4._________ 5._________
Generation 0 20 20 20 20 20
Generation 1
Generation 2
Generation 3
Record any observations.

Data Analysis:

Create a graph that tracks the changes in the prey population’s colors.

Conclusion:

Be sure to answer the following reflection questions in the conclusion of your lab report:

How do the original and surviving prey populations compare?
How did the colors of each type of prey affect its population size over time?
What color(s) seemed to camouflage the best in this habitat? What color(s) seemed to stand out the most?
How do you predict the data would change if you continued? Explain your answer.
How would these results change if the colors or patterns of the habitat were to change?
Identify at least two things that are unrealistic and two things that are realistic about this exercise.
What traits could help a predator be more “fit” in this model environment?
Describe other adaptations besides color that could affect an individual’s survival.

Answer 13

This is my last retricemt I know there is a way to complete this online I just needed to be pointed in the right direction

Answer 14

it looks like my initial assumption was correct; but it is a hands on lab.

What would you form as your hypothesis?

Answer 15

Natural selection changes the genetic makeup of a population by favoring some genotypes over others.

Answer 16

My Hypthesis might be:

Prey that matches its habitat are harder to spot; and therefore get to live long enough to pass on their genes which weeds out the colors of the population that dont fit in with the environment.

Answer 17

The rest of it is testing the hypothesis using the materials and methods that they suggest

Answer 18

get 5 colors; cut into 20 little squares each

toss them on a colored fabric, and get 2 people to pick up the first 75 pieces as fast as they can; this means that they are going to pick up the ones that are easiest to spot first.

the remaining pieces each produce 3 new children of the same color

Answer 19

repeat the process and record the results

Answer 20

that may be true but for me effectively testing it is the problem because materia
ls i lack do youthing that there may be anyway to effectively research and virtual test online

Answer 21

i know of now online way to demonstrate this :/ srry

Answer 22

well thanks for helping you have been very helpful i appreciate taking your time

Answer 23

did you ever get this done?
