1. Find the graph paper in your kit and graph your results by putting the generation number along the x-axis and the number of bears along the y-axis. When drawing the lines, use a different color to represent each type of bear. (Make sure to indicate which color goes with which type of bear.)

2. Summarize the trends you see in each population from each generation.

a. Dark bears-

b. Light bears-

3. Explain how this experiment demonstrated natural selection.​

Based on the nature of their environment, natural selection will favor the bear type that is better suited to its environment.

Natural selection is a process of evolution in which organisms which are better suited to their environment are selected for survival.

In the bear population, natural selection will favor each bear type that is better suited to its environment.

In cold and icy environments, the light bears are better suited to their environment and are naturally selected for survival.

In temperate and warm climates, dark bears are better suited to their environment and are naturally selected for survival.

Therefore, natural selection will favor the bear type that is better suited to its environment.

color goes with which type of bear.)

Okay, this is REALLY simple. Just make a graph with the info given to you.

2. Summarize the trends you see in each population from each generation.

a. Dark bears— Dark Bears with their arms up always had double to amount of the Dark bears with their arms down, and past Generation 3 the Dark Bears had more numbers than the Light Bears

b. Light bears— Light Bears start off with only arms down, and when arms up bears are introduced, they are more common/prevalent for the majority of the generations, having usually twice as much as the bears with the arms down.

3. Explain how this experiment demonstrated natural selection.

This experiment shows natural selection by hosting events in which certain bears are put more at a risk than other bears, such as environment changes favoring dark bears, or bears with their arms up.

4. If the environmental situation changes, is it possible for a population to be restored?

Via adaptations, it is completely possible for a bears population to thrive again, but perhaps not with the same characteristics.

5. How can natural selection help explain how a population becomes extinct?

As the environment changes, it may favor a species less and less, which leads to their decline, if they are unable to change with the times and adapt, the species will go extinct as it is no longer fit in its environment.

6. Which generations saw a population altering incident? Use your imagination to invent a possible environmental incident that could have caused this shift in populations.

The Light Bears faced a decline, and most bears with their Arms Down faced a decline too. Light bears could be explained via environmental factors, such as their original habitat being snowy, and without the snow they're more visible given their lighter colors. Arms down could simply be a dominants v recessive trait

7. How can environment impact a particular population of a species?

If a certain species is not fit for the changes made in an environment, it could result in either their extinction, or a mutations/adaptations so that the species can continue to thrive.

8. What are some natural reasons that animals in a population might die?

Competition, not enough resources, environmental changes.

9. What are some man-made reasons that animals in a population might die?

Things such as deforestation, overhunting, and introducing invasive nonnative species.

10. What are some ways that man has helped animals maintain their populations?

Protecting endangered species, rehabilitating injured animals, making animal reservations, etc.

Why is cellulose important for explaining how carbon atoms get "locked up" (stored) in a tree as long as it is alive?

O Cellulose is what is produced in photosynthesis.

O Cellulose is used to make new cell walls, when tree cells divide, which become part of the tree.

O Cellulose is made up of CO2 molecules from the atmosphere that stay in the tree.

O Cellulose is what the trees use to make starch, which stores energy for the tree to use later.

Naomi runs a computer simulation for a population of mice in a meadow ecosystem. The simulation begins with 100 mice, divided equally among brown and white variants. The variants are similar apart from their body color. A mating of a white and brown mouse may produce a speckled mouse, which is mostly brown with some white markings. The table shows the numbers of each mouse variant over 7 reproduction cycles. Only adult mice are reported in the table.
Which of these events did the computer MOST LIKELY include in its simulation?
A. After cycle 2, a disease arrived that affected white mice only.
B. After cycle 2, a predator arrived that saw white mice more easily than brown mice.
C. After cycle 4, brown mice and white mice began living separately, and stopped interbreeding.
D. After cycle 4, a predator arrived that saw white mice more easily than brown mice.
E. After cycle 4, a disease arrived that affected brown mice only.
