Aloe Vera Plant
Earthworm

On the Galapagos Islands, Charles Darwin studies many species of _____________ [a type of bird], and found that they had different types of beaks based on which type of food they eat.
Finches
100
Fossils are generally formed in which of the following kind of rock?
Igneous
Sedimentary
Metamorphic
Sedimentary - the other ones can cause damage that destroys fossils [Igneous is volcanic rock and metamorphic is formed under a lot of heat and pressure]
100
In the fossil record, there are two fossils, fossil A and fossil B. Fossil A is buried deeper than fossil B and is therefore ___________ than fossil B. [fill in the blank]
older - fossils that are deeper are older than fossils near the surface.
100
Name all three domains of life
Bacteria
Archaea
Eukarya
200
What word describes an organism that is made up of many cells rather than only one cell?
Multicellular.
One cell is unicellular
200
What is the difference between natural selection and artificial selection
Artificial selection is by humans - selecting what type of chicken to raise [page 18]
Natural selection is without human intervention.
200
Golden aged tree sap which often traps insects is known as ____________.
Amber
200
This is the term for when an entire species of a particular organism disappears completely.
Extinction
200
A step by step procedure of classifying organisms based on shared characteristics is known as a ______________. [Hint, we used this in class for aliens and salamanders.]
The dichotomous key
300
What is the fundamental unit of living things?
The cell
300
What are the four parts of natural selection?
overproduction
genetic variation
selection
adaptation
300
The Yeast - because there are 42 differences in the proteins between the yeast and the chimpanzee.
300
This era is known as the era of mammals. Reptiles stopped being dominant, and the earth was largely populated by more intelligent mammals.
Cenozoic Era. [This is the current era we are living in.]
300
Name the four kingdoms within the Domain Eukarya
Animalia
Protista
Plantae
Fungi
400
In living things, a stimulus produces a _________.
[Fill in the blank]
Response - something that the organism does when there is a stimulus is called a response.
400
Explain the difference between inherited traits and acquired traits.
Which of these traits is passed on?
Inherited traits - traits such as eye color, skin color, etc, that are a result of the person's DNA [in the nucleus of the cell].
Acquired traits - traits such as muscularity, which are the result of the person's actions when the live [such as lifting weights]
Inherited traits are passed on, while acquired are not.
400
A bat and a cat have the same numbers and types of bones in their arms. This can provide evidence for evolution. This type of similarity is known as what?
Common structures
400
This organism first began to produce oxygen in the early earth during the Precambrian period, so that later organisms could use the oxygen to live.
cyanobacteria
400
Organisms A and B are in the same phylum.
Organisms C and D are in the same order
Organisms E and F are in the same genus.
Which of these pairs of organisms are likely the most closely related?
E and F.
They are in the same genus, so they are very likely very similar kinds of creatures (like two species of foxes). The higher up you go in the pyramid, the more types of different creatures there are in the group. see page 57
500
Organisms try to maintain a stable internal environment, including a proper temperature, a proper salinity, etc. This stable state is known as ____________.
Homeostasis
500
An organism such as a rabbit produces lots and lots of offspring.
Which of the 4 parts of natural selection is represented by this type of behavior?
Overproduction - This means that the animal or plant produces more offspring than usually survive to adulthood. The rabbit produces lots of babies, so that some of them survive and carry on the DNA of the rabbit.
500
How does a cast fossil form?
A cast fossil forms when an organism dies in sedimentary rock. The organism eventually disappears, leaving an empty cast in the rock. Other minerals later on come by and form new rock in the shape of the old dead and now disappeared organism.
500
A mass extinction of dinosaurs occurred during the ____________ era. [fill in the blank]
Mesozoic

What is one important advantage of a scientific name over a common name?
A scientific name is always one name for an organism. But common names vary all over the world. [Remember the example of the cougar/puma/mountain lion/panther]
