Evolution/Diffusion Test

Question 0

Evolution

Answer 0

The process by which species may change over time

Question 1

Who developed the theory of evolution?

Answer 1

Charles Darwin

First Person who came up with the theory

Question 2

Theory

Answer 2

An explanation that has been scientifically tested and supported

Question 3

Natural selection?

Answer 3

Those organisms with the most beneficial traits are more Likely to survive and reproduce

Question 4

Variation

Answer 4

There is a variation (variety) in every population

Question 5

Competition

Answer 5

Organisms compete for limited resources

Question 6

Offspring

Answer 6

Organisms produce more offspring than can survive

Question 7

Genetics

Answer 7

Organisms pass genetic traits on to their offspring

Question 8

What is evidence to evolution?

Answer 8

Fossils

Fossil records

Question 9

How do we know organisms existed millions of years ago?

Answer 9

There is a fossil record

Based on fossil records found, the horse evolved from a small animal(size of a dog) to today’s larger sized horses

Question 10

What is the fossil record chart?

Answer 10

This chart shows the earths history revealing the many changes that occurred to species over the past billions of years
The earth is 4.6 billions years old
We have fossil evidence of organisms that once lived on earth

Question 11

Speciation

Answer 11

A lineage-splitting event that produces two or more separate species

Question 12

What is with speciation?

Answer 12

At that branching point, and every other branching point on the tree, is a speciation event
At that point, genetic changes resulted in two separate lineages, where previously there had just been one lineage

Question 13

Allopatric speciation

Answer 13

A PHYSICAL BARRIER divides one population into two or more populations
After a long period of time, the two populations will contain organisms that can no longer successfully breed with one another

Question 14

Sympatric Speciation

Answer 14

Occurs when a species evolves into a new species WITHOUT A PHYSICAL BARRIER.
The ancestor species and the new species live in the same habitat during the speciation process. THIS USUALLY HAPPENS TO PLANTS

Question 15

What are the causes of speciation?

Answer 15

Geographic isolation

Question 16

Geographic isolation

Answer 16

Common way for the process of speciation to begin
Rivers change course, mountains rise, continents drift, organisms migrate, and what was once a continuous population is divided into two or more smaller populations

Question 17

Classification

Answer 17

The grouping of objects or information bases on similarities

Question 18

Taxonomy

Answer 18

The branch of biology that groups and names organisms based on different characteristics

Question 19

How are organisms ranked?

Answer 19

Organisms are ranked in taxonomy that ranges from having broad characteristics to very specific characteristics

Question 20

How many levels are there in taxonomy and how are they placed?

Answer 20

8 levels

Largest—-Smallest

Question 21

What are the 8 levels of taxonomy?

Answer 21

Domain
Kingdom 
Phylum
Class
Order
Family
Genus
Species

Question 22

What are the rules to Binomial Nomenclature?

Answer 22

1) Genus and species
2) The Genus is capitalized, the species is lowercase
3) it is either in italics or underlined

Question 23

What is the Dichotomus Key?

Answer 23

Another method of grouping organisms based on similar characteristic. The closer they are on a tree, the more related they are to each other.

Question 24

Osmosis

Answer 24

The movement of WATER MOLECULES from an area of high concentration to an area of low concentration
Cell membranes are completely permeable to water, therefore, the environment and the cell are exposed and can have a dramatic effect on the cell.
