C15. Exocytosis

Front

A process in which a cell releases substances to the extracellular environment by fusing a vesicular membrane with the plasma membrane, separating the membrane at the point of fusion and allowing the substance to be released.

Back

C18. Facilitated Diffusion

Front

A process in which substances are transported across a plasma membrane with the concentration gradient with the aid of carrier (transport) proteins; does not require the use of energy.

Back

C11. Environment

Front

The total surroundings of an organism or a group of organisms.

Back

C5. Endemic Species

Front

A species that is found in its originating location and is generally restricted to that geographic area.

Back

C21. Forensics

Front

The science of tests and techniques used during the investigation of crimes.

Back

C1. Dominant Inheritance

Front

A pattern of inheritance in which the phenotypic effect of one allele is completely expressed within a homozygous and heterozygous genotype.

Back

C13. Eukaryote

Front

A type of organism composed of one or more cells containing a membrane-bound nucleus, specialized organelles in the cytoplasm, and a mitotic nuclear division cycle.

Back

C8. Endosymbiosis

Front

A theorized process in which early eukaryotic cells were formed from simpler prokaryotes.

Back

C12. Enzyme

Front

A protein that increases the rate of a chemical reaction without being changed by the reaction; an organic catalyst.

Back

C17. Extracellular

Front

Located outside a cell.

Back

C23. Founder Effect

Front

A decrease in genetic variation caused by the formation of a new population by a small number of individuals from a larger population.

Back

C7. Endoplasmic Reticulum (ER)

Front

An organelle, containing folded membranes and sacs, responsible for production, processing, and transportation of materials for use inside and outside a eukaryotic cell. There are two forms of this organelle: rough ER that has surface ribosomes and participates in the synthesis of proteins mostly destined for export by the cell and smooth ER that has no ribosomes and participates in the synthesis of lipids and steroids as well as the transport of synthesize macromolecules.

Back

C3. Ecosystem

Front

A system composed of organisms and nonliving components of an environment.

Back

C20. Food Web

Front

A complex arrangement of interrelating the flow of energy between interdependent organisms.

Back

C14. Evolution

Front

A process in which new species develop from preexisting species (biological evolution or macroevolution); a change in the allele frequencies of a population of organisms from generation to generation.

Back

C10. Energy Transformation

Front

A process in which energy changes from one form to another form while some of the energy is lost to the environment.

Back

C6. Endocytosis

Front

A process in which a cell engulfs extracellular material through an inward folding of its plasma membrane

Back

C16. Extinction

Front

A term that typically describes a species that no longer has any known living individuals.

Back

C2. Ecology

Front

The study of the relationships between organisms and their interactions with the environment.

Back

C22. Fossils

Front

The preserved remains or traces of organisms that once lived on Earth.

Back

C9. Energy Pyramid

Front

A model that illustrates the biomass productivity at multiple trophic levels in a given ecosystem.

Back

C19. Food Chain

Front

A simplified path illustrating the passing of potential chemical energy (food) from one organism to another organisms.

Back

C4. Embryology

Front

The branch of zoology studying the early development of living things
