Evolution
What do we call a trait that helps an organism survive and reproduce in its environment?
What is Adaptaion.
A relationship where one organism benefits and the other is harmed, like a tick on a dog.
What is Parasitism?
The place where an organism lives and gets its food, water, and shelter.
What is a habitat?
The molecule that carries the genetic code from the nucleus to the ribosome
What is mRNA?
Preserved remains of ancient organisms, such as trilobites or dinosaur bones, that show connections to modern species.
What are fossils?
The process by which organisms better adapted to their environment survive and reproduce more successfully.
What is natural selection?
The type of succession that begins in an area with no soil.
What is primary succession?
A group of the same species living in the same area.
What is a population?
The process where the cell uses mRNA to build a protein.
What is translation?
Structures like human arm bones and whale flippers that share a common evolutionary origin.
What are homologous structures?
A change in the DNA sequence of an organism that can lead to new traits.
What is a mutation?
The stable, final community that forms at the end of succession.
What is a climax community?
The role or job an organism has in its ecosystem.
What is a niche?
The molecule that carries the correct amino acid to build the correct protein.
What is tRNA
Structures like the wings of a bird and the wings of an insect perform the same function but evolved independently in different groups.
What are analogous structures?
The preserved remains or traces of ancient organisms.
What is a fossil?
The process that happens after a forest fire, where life returns to the area.
What is secondary succession?
All the living and nonliving things in a particular area make up this.
What is an ecosystem?
The process where the cell uses DNA to build an mRNA molecule.
What is transcription?
The tiny pelvic bones found in whales, which no longer serve their original function, are examples of what kind of evolutionary evidence?
What are vestigial structures?
When a species changes over time in response to environmental pressures, this is called:
What is Evolution?
The first species to colonize barren areas, like lichen on rocks.
What are pioneer species?
The maximum population an environment can sustainably support over time.
What is carrying capacity?
The specific location in the cell where translation occurs.
What is the cytoplasm?
The fact that embryos of fish, birds, and humans all have gill slits at certain stages of development is used as evidence for evolution from a common ancestor. What field of study provides this evidence?
What is embryology?
