Nowhere to Hide Teacher Sheet

Introduction

Students should use the resources on the Nowhere to Hide student esheet to answer the questions on the student sheet. This sheet provides you with the answers to the questions.


Answers to the matching activity found on the student sheet. The terms (numbered items) should be
matched with the appropriate definition (lettered items).

1. What is natural selection?   E

2. What is selection?   D

3. What is evolution?   F

4. What is adaptation?   B

5. What is another term for natural selection?   H

6. What is a variation?   A

7. What is heredity?   I

8. What is a species?   G

9. What is extinction?   C

A. All the observable characteristics of an organism (e.g., shape, size, color, and behavior) that result from the interaction of its total genetic makeup with the environment.

B. The process by which an animal or plant changes in response to its environment.

C. Dying out or termination of a species.

D. The preferential survival and reproduction (or elimination) of individuals with a certain genetic makeup via means of naturally or artificially controlling factors.

E. The process by which an organism adapts to its environment by selectively reproducing changes in its genetic makeup that are necessary for survival.

F. The biological theory that animals and plants have their origin from other types of organisms and that distinguishable differences are due to changes in successive generations.

G. A classification composed of related organisms that share common characteristics and can interbreed.

H. Survival of the fittest.

I. Transmission of physical and mental traits from parents to offspring through their genes.

 

Nowhere to Hide Interactive Questions
1. Which bugs were eaten more when there was a low level of pollution (background green)?
The orange bugs.

2. Which bugs were eaten more when there was a high level of pollution (background orange)?
The green bugs.

3. What factor determined the survival of the bugs? Why?
Their color. If the level of pollution was low, then the orange bugs were most visible to the birds, thus they were eaten more readily. And, if the level of pollution was high, then the green bugs were most visible to the birds, thus they were eaten more readily.

4. If the pollution level is high for an extended period of time, does this affect the survival of the green
bugs?
Yes.

5. Would they increase or decrease over time?
Decrease.

6. If the pollution level is low for an extended period of time, does this affect the survival of the orange
bugs?
Yes.

7. Would they increase or decrease?
Decrease.

8. In natural selection, the organisms that are best suited to survive in an environment have the most babies and grow in numbers, while organisms that aren't as well suited to the environment shrink and disappear.
True.

9. Do you think this process occurs over a short period of time or a long period of time?
Long period of time.
