Genetics
An organism that is genetically identical to the organism from which it was produced.
Clone
A diagram showing evolutionary relationships of organisms with a common ancestor.
Cladogram
The amount of different species in an ecosystem.
Biodiversity
Name a greenhouse gas
Carbon dioxide, methane, nitrous oxide
The variable that is chosen by the experimenter is the
Independent variable
The units of heredity that make up the chromosomes; pieces of DNA that make proteins.
Genes
A measure of an organism's reproductive success.
Fitness
A consumer or organism that can't make its own food.
Heterotroph
Give an example of a fossil fuel.
Coal, Natural gas, Petroleum, Oil
Things that are kept the same in an experiment.
Constants
A change in the DNA sequence that affects genetic information.
Mutation
Any trait that helps an organism survive and reproduce under a given set of environmental conditions.
Adaptation
The place where an animal/plant lives.
Habitat
Phenomena caused by the burning of fossil fuels, which produce gases such as CO2 that then get trapped in Earth's atmosphere.
Greenhouse Effect
The "normal" group or situation that is used for comparison in an experiment.
Control
The process of inserting a gene from one organism or species into the DNA of another.
Genetic engineering
The gradual change in species over time.
Evolution
Nonliving parts of the environment.
Abiotic
Destruction of forests that are caused by human activity.
Deforestation
Which variable goes on the y (vertical) axis of a graph? (And is generally the second column in a data table)
Dependent variable
The human process of selecting organisms with desired traits.
Selective breeding
The evolution of new species.
Speciation
The specific job done by an organism or population of organisms in the ecosystem.
Ecological niche
Identify one human action that could reduce the amount of greenhouse gases entering the atmosphere.
Driving less gas-powered cars (carpooling, walking more, using public transportation, or electric vehicles),
Switching to renewable energy sources (such as wind, solar, geothermal),
Reduce deforestation and/or plant more trees
What can be done to make an experiment more valid?
Repeat the experiment to see if the results are the same,
Increase the sample size.
