Question | Answer |
What is Evolution? | The gradual change in a species over time |
What is Natural Selection? | The process by which individuals that are better adapted to their enviroment are more likely to survive and reproduce than other members of the same species |
What are 3 factors that affect natural selection? | Overproduction Competition Variations |
What is a fact? | A natural phenomenon repeatedly confirmed by observation |
What is a Theory? | A well-substained explanation of some aspect of the natural world that typically incorporates many confirmed observations, laws, and succesfully verified hypothesis |
What in a hypothesis? | a possible and testable statement about a natural phenomanon |
What 4 features do all tetrapods have in common? | four limbs a backbone with spurs a pelvis attached to the backbone nosterals |
What are 2 factors that effect evolution? | Genetic mutation Changes in the enviroment |
What is the Theory of Natural Selection? | "survival of the fittest"- best adapted will survive, thrive, and pass on its genes when it reproduces |
When does a species become extinict? | when no members of that species are still alive |
How could a sudden change in a species habitat cause the species extinction? | If the enviroment changes quickly, animals wouldn't be able to eat the same things, or live in the same places. |
What is the study of similarities in body structure called? | Comparitive anatomy |
How do similarities in DNA and protiens provide evidence of an evolutionary relationship between 2 species? | 2 speicies with similarites in DNA and protiens probably evolved fromt the same ancestor. |
predators such as segals and crabs are an enviromental risk to newly hatched sea turtles. Why are some newly hatched turtles better able to survive than others in their enviroment? | They probably have a harder shell,and stronger flippers, and are probably faster, smaller and better camoflouged. |
Which domainincludes only prokaryotes? | Bacteria |
Which group of organisms includes only multicellular heterotrophs? | Animals |
What happens when a species gets geographicly isolated? | a new species forms |
Which kingdom includes both unicellular and multicelllular organisms? | fungi |
What are the the factors that affect natural selection? | Overproduction variations competition selection enviroment genes |
Why do scientists organize living things into groups? | so the organisms are easy to study |
What is a branching tree? | a diagram that shows how scientists think different groups of organisms are related |
What is taxonomy? | the scientific stufy of how living things are classififed. |
What is the role of genes in evolution? | without genetic variation, all members of a species would be the same |
What does an organism's scientific name consist of? | genus species binomial nomenclature |
What are the only traits that can be acted upon by natural selection? | Traits that are controlled by genes |
Who developed the naming system that groups organisms? | Carolus Linnaeus |
A trait that helps an organism survive is called an __________ | adaptation |
What is a genus? | a classification group that contains similar, closely related organisms |
The more classification levels that 2 organisms share, the more _________ they have in common | characteristics |
How are organisms placed into domains and kingdoms? | Their cell type,their ability to make food, and the number of cells in their body |
What 4 kingdoms are eukaryotes classified into? | Protists, fungi, plants, or animals |
What are Prokaryotes? | organisms whose cells lack a nucleus |
What are Eukeryotes? | organisms with cells that contain nuclei |
