QuestionAnswer
What is evolution? The process of change over time
What was Charles Darwin's contribution to science? Darwin developed a theory of evolution that explains how modern organisms evolved over long periods of time from common ancestors.
What did Darwin notice about biodiversity around the world? Places around the world that had similar habitats often had different animals that were ecologically similar.
What are fossils? The preserved remains or traces of ancient organisms.
What did Darwin notice about biodiversity about biodiversity within a local area? Darwin noticed that different, related species often lived in different habitats within a local area.
What did Darwin notice when he compared some fossils to living species? Darwin noticed that some fossils of extinct animals were similar to living species.
What are acquired characteristics? Traits that change during the life of an organism.
What is deep time? The idea that Earth's history is so long that it is difficult to imagine
What is artificial selection? Selective breeding of plants and animals to promote the occurrence of desirable traits in offspring.
How is variation used in artificial selection? Nature provides the variation, and humans select the traits they find useful.
Organisms with traits that are the best match to their environment survive and leave more offspring.
When does natural selection occur? When more individuals are born than can survive;there is variation and adaptation;individuals have different fitness rates.
What is fitness? How well an organism can survive and reproduce in its environment .
What is adaptation? Any heritable trait that helps an organism survive in its environment.
What is biogeography? The study of where organisms live and where their ancestors lived in the past.
What are homologous structures? Structures that are shared by related species and that have been inherited from a common ancestor.
What are analogous structures? Structures that share a common function but are not structurally related.
What are vestigial structures? Inherited structures that have lost much of their original function.
What do anabolic pathways do? Build up organic molecules to store energy for later use
What is the equation for aerobic respiration? C6H12O6 + 6O2 + 6H2O --> 6CO2 + 12H20 + energy (ATP)
What is the equation for photosynthesis? 6CO2 + 12H2O + energy (light) --> C6H12O6 + 6O2 + 6H2O
What is ATP? Adenosine Triphosphate
What is ATP made up of? Adenine, Ribose(sugar), and three phosphate groups.
Living things that make their own food are known as. Autotrophs
