The diagram shows light- and dark-colored beetles that live on a tree.
Which result is most likely to occur to the beetle population due to predation over time?
A zoologist recorded the following information regarding breeding habits of the Kiwi bird:
The Great Spotted Kiwi can only lay a single egg once per year. While the female Kiwi reproductive cycle lasts from July through February, breeding season (when Kiwis lay their egg) is typically in January. The male kiwi then incubates the egg until it hatches in April or May.
Based on the information in the charts, what is the most likely explanation for the Great Spotted Kiwi to lay their eggs in January instead of any other month?
At the beginning of your simulation, 50% of the moths were light and 50% were dark. What percent of the moths were LIGHT at the end?
At the beginning of your simulation, 50% of the moths were light and 50% were dark. What percent of the moths were DARK at the end?
In the dark forest, which type of moth was better able to survive?
If these moths belong to the same species, what determines which ones survived?
Given the data below, which type of environment was this collected from?
How do different animals use color as an adaptation?
Match the 5 Principles of Natural Selection
| Draggable item | arrow_right_alt | Corresponding Item |
|---|---|---|
Struggle for survival | arrow_right_alt | Differences in traits within the species |
Evolution | arrow_right_alt | Producing many offspring, Increasing the chance that at least a few will survive |
Over-reproduction | arrow_right_alt | Organisms must compete for limited resources |
Variation in species | arrow_right_alt | Only those who survive can pass on traits (reproduce) |
Adaptation | arrow_right_alt | The environment determines which organisms survive |
Nature chooses | arrow_right_alt | A gradual change in heritable traits, over time |
The fittest will survive | arrow_right_alt | A good trait in a population that increases the chances of survival |
Analyze the following data to draw conclusions and make inferences about the populations involved. Remember to use your knowledge on Natural Selection and advantageous adaptations.
All of the following statements are supported by this data except?
Before the industrial revolution (year 1760), the population of white moths was greater than black moths. As years passed (1760 - 1840), the pollution of factories affected tree trunks making them darker than normal. What can be inferred to be the cause of change in the moth population?
Based on the pie chart above, what can be concluded about the future population of birds? Choose two answer choices.
Adaptations can be:
Which environment best suits this adaptation?
| Draggable item | arrow_right_alt | Corresponding Item |
|---|---|---|
Being able to run at high speeds | arrow_right_alt | An area where food is hard to find |
Having very thick fur | arrow_right_alt | An area where predators are fast |
Small pointy beaks to reach inside trunks | arrow_right_alt | An area with cold temperature |
Being able to run at high speeds | arrow_right_alt | An area where there are fast predators |
In this scenario, the light mouse population is , while the dark mouse population is .
The mice are able to survive and reproduce better, because they are .
The adaptation (good trait) in this scenario is .
A population of turtles that has both short necks and long necks lives in an area where food is found at both high and low bushes. A virus kills off all the low bushes, leaving only tall bushes for the turtles to eat. The picture below shows the change in the population over time.
In this scenario, the turtle with the has the higher fitness because .
The adaptation in this scenario is .
There must be (differences ) in species which increases the chances of survival.
In this example, the variation present in the beetles is
A population of turtles that has both short necks and long necks lives in an area where food is found only at tall bushes.
The variation in this example is. Variation is important is a species because .
What would happen to the turtle population if they were ALL short necked?
What type of environment do you think this data was collected from?
Natural selection is based on all of the following EXCEPT..
Some organisms have traits that improve their ability to survive and reproduce. If the traits also help their offspring survive and reproduce, then which of the following will most likely increase?
Use the graph below to answer the following questions. The solid line represents the dark colored moth frequency. The dashed line represents the light colored moth frequency.
Before 1850, the moth color that was more common was the . Between 1900 and 1950, the moth color that was more common then was the .
The change in the percentage of the light-colored moths between 1850 and 1900 , and the change in the percentage of dark-colored moths during the same period of time .
The moth color that was more fit between 1850 and 1900 was the .

In the light forest, why did the dark moth population decrease?
The moths were able to survive because .
