Quizs - Bio CP 2nd Semester Final Review -Vocabulary Terms

Trait variation

• Differences among traits; Traits occur in more than one form

• Uniformity in traits across a population

• The process of natural selection

• The genetic makeup of an organism

Heritable

• When a trait can be passed from a parent to a child

• A trait that is only found in one generation

• A trait that is influenced by environmental factors

• A trait that cannot be passed to offspring

Empirical evidence

• A type of evidence based on logical reasoning and deduction.

• A source of knowledge gained through observation or experimentation, and it provides information to support the theory of natural selection.

• A form of evidence that relies solely on theoretical models.

• A type of evidence that is only applicable in controlled laboratory settings.

Species

• A group of organisms that can interbreed to generate fertile offspring

• A classification level that includes multiple types of organisms

• The first part of an organism's scientific name

• A type of habitat where organisms live

DNA

• Forms the hereditary material of all life on Earth.

• Is a type of protein found in cells.

• Is responsible for energy production in cells.

• Is a carbohydrate that provides structural support.

Allele

• A contrasting/alternate form/version of a gene.

• A type of mutation in DNA.

• A segment of RNA that codes for a protein.

• A structure that carries genetic information.

Trait

• A specific characteristic that varies from one individual to another and are inherited from parents.

• A random feature that does not affect an organism's survival.

• A temporary condition that changes with the environment.

• A learned behavior that is not passed down genetically.

Adaptation

• A process by which organisms become extinct due to environmental changes.

• A process by which the heritable characteristics of a population change such that the organisms in the population become better able to survive and reproduce in their environment.

• A method of artificial selection to enhance certain traits in a species.

• A phenomenon where organisms migrate to different environments for better survival.

Crossing-over

• The exchange of genetic material between homologous chromosomes.

• The process of cell division in somatic cells.

• The formation of new alleles through mutation.

• The separation of sister chromatids during anaphase.

Chromosome

• A single piece of DNA that contains genes.

• A type of protein that helps in cell division.

• A structure that carries RNA molecules.

• A component of the cell membrane.
