Natural Selection & Adaptations
Unlike natural selection, this occurs when humans breed organisms for specific desired traits, like different dog breeds.
What is, artificial selection?
This term refers to the observable physical characteristics of an organism, such as eye color or height.
What is, phenotype?
Anything that has mass and takes up space (volume).
What is, Matter.
This type of adaptation allows an animal, like a peppered moth or a snowshoe hare, to blend in with its surroundings.
What is, camouflage?
Identified as a double helix in 1953, this molecule carries the primary hereditary information for all living organisms.
What is, DNA?
The smallest unit of ordinary matter that forms a chemical element.
What is, an Atom.
A bird migrating south for the winter is an example of this specific type of adaptation.
What is, a behavioral adaptation?
This type of diagram is used to trace the genetic history of a specific trait or disorder across several generations of a family.
What is, a pedigree chart?
This subatomic particle carries a negative charge and orbits the nucleus in a "cloud."
What is, an electron?
This occurs when one harmless species evolves to look like a dangerous or unpalatable one to avoid predators.
What is, Mimicry?
This term describes the condition where a person has three copies of chromosome 21 instead of two, resulting in a specific genetic disorder.
What is, Down Syndrome?
This state of matter has a definite volume but takes the shape of its container.
What is, a liquid?
This is the primary source of new genetic variations within a population.
What is, mutations?
This term refers to the genetic makeup of an organism, representing the specific alleles (like Bb) rather than the outward appearance.
What is, a genotype?
Found in the center of an atom, these two particles make up the vast majority of its mass.
What is, protons and neutrons?
