What is a species?

A group of similar organisms that can mate and reproduce offspring, that can also mate and reproduce.

100

Only individuals with a desired trait are bred describes what type of "selection"

Artificial Selection

100

What is one way a mutation could increase an organisms fitness?

A mutation that leads to an organism blending in better with their environment.. other possible answers as well.

100

Small gradual changes over time..

Microevolution

100

The common ancestor that all organisms share is called?

LUCA

200

Who created the scientific theory of evolution?

Charles Darwin

200

There are 3 factors that play a role in natural selection, what are they?

- Over production

- Variation

- Competition

200

occurs when individuals with new alleles physically move from one population to another.


DD: Does this increase or decrease genetic variation?

Gene Flow 

DD: increase

200

Similar bone structure that is inherited by a common ancestor is known as..

Homologous structures.

200

Scientists believe bacteria evolved to become what 2 organelles?

Mitochondria and Chloroplasts 

300

Any difference between individuals of the same species is known as...

Variation.

300

A mutation is any change to an organisms....

Genetic Material

300

What 2 things does an organisms "fitness" represent?

Ability to survive and reproduce

300

Major changes overtime, typically leading to a new species being created.

Macroevolution.

300

Symbiosis is the interaction between 2 similar organisms..


Endosymbiosis is when an organism moves...

Inside another organisms cell.

What's Mr. Browns favorite candy?

Sour Patch Watermelons

Darwin studied finches while on the Galapagos Islands, what adaptation did he notice, and how did that adaptation come about?

Their beak shape was based on the type of food they ate, or that was available on the island they were on.

400
A new development is being built in babcock in an area heavily populated by black snakes. When construction started, most of the black snakes were killed. What is this an example of?

Genetic drift

400

Climate change such as the Ice Age can lead to extinction of certain organisms. What are two other factors that could lead to extinction?  

new predators, disease, and competition with other species.

400

What 4 molecules make up proteins?


DD: what is the other molecule that can sometimes be present in proteins?

Oxygen, Nitrogen, Carbon, Hydrogen


DD: Sulfur

500

an inherited trait or behavior that helps an organism survive and reproduce.

Adaptation

500

What 3 mechanisms can lead to evolution?

Natural Selection, Artificial Selection, and Mutations

What are 3 of the 4 important jobs that proteins have?

Carry materials through the body

Act as a messenger

Help fight diseases

Carry out chemical reactions
