Adaptation explained in an easy to understand way.
Adaptation
A trait that helps an organism survive in its environment. Adaptation. In simple terms, adaptation is when animals or plants change over time to better fit their environment.
Allele frequency
The proportion of one allele of a gene compared to other alleles of the same gene. Allele frequency. Allele frequency is how often a specific version of a gene shows up in a group.
Carrying capacity explained in an easy to understand way.
Carrying capacity
The largest population that an environment can support. Carrying capacity. Carrying capacity is the maximum number of living things an area can support without running out of resources.
Exponential growth explained in an easy to understand way.
Exponential growth
A dramatic population increase in a short time. Exponential growth. Exponential growth means the population multiplies rapidly over time, like in a chain reaction.
Fitness
The ability of an organism to survive and reproduce in its environment. Fitness. Fitness means how well an organism can live and have babies in its environment.
Hardy Weinberg principle
States that allele frequencies in a population are constant unless a factor causes change. Hardy Weinberg principle. The Hardy-Weinberg principle explains how the genetic makeup of a large, random-mating population will stay the same over generations unless influenced by outside factors.
Logistic growth explained in an easy to understand way.
Logistic growth
When population growth starts slow, then sees exponential growth, then slows again. Logistic growth. In simple terms for Grade 8, logistic growth is how a population grows quickly at first, then slows down as resources run out.
Natural selection explained in an easy to understand way.
Natural selection
The individuals best suited to survive in an environment. Natural selection. Natural selection is the process where organisms with traits better suited to their environment are more likely to survive and reproduce.
Trait explained in an easy to understand way.
Trait
Any characteristic of an organism. Trait. In Grade 8 science, a trait is a feature or quality of a living thing, like brown eyes or tall height.
