Disease

Any impaired function of the body with a characteristic set of symptoms

Application:

Human biological risk

distribution
Distribution

Areas of the world in which a species live

Application:

Evolution shapes ecological niches and determines species distributions

disturbance
Disturbance

An event, caused by a physical, chemical, or biological agents, resulting in changes in population size or community composition

Application:

Ecosystem ecologists are often interested in how disturbances affect the flow of energy and matter through an ecosystem

divergent plate boundary
Divergent Plate Boundary

An area beneath the ocean where tectonic plates move away from each other

Application:

Attributed to the cause of seafloor spreading, which creates new lithosphere and brings important elements to the surface of Earth.

slide5
DNA

(Deoxyribonucleic acid) A nucleic acid, the genetic material that contains the code for reproducing the components of the next generation, and which organisms pass off into their offspring

Application:

Organic compound found in all living things. Without it we would not exist.

dose response study
Dose-Response Study

A study that exposes organisms to different amounts of a chemical and then observes a variety of possible responses, including mortality or changes in behavior or reproduction

Application:

To assess the risk a chemical poses to any organism by determining the concentrations that cause harm.

doubling time
Doubling Time

The number of years it takes a population to double

Application:

Used to calculate future population size.

e horizon
E Horizon

The zone of leaching that forms under the O horizon or, less often, the A horizon.

Application:

One of the layers in soil in which iron, aluminum, and dissolved organic acids are transported through and removed then deposited in the B horizon.

earthquake
Earthquake

The sudden movement of Earth’s crust caused by a release of potential energy along a geologic fault and usually causing a vibration or trembling at Earth’s surface

Application:

Part of a cycle of surfacing and sinking of magma from the mantle.

ebola hemorrhagic fever
Ebola Hemorrhagic Fever

An infectious disease with high death rates, caused by the Ebola Virus

Application:

An emergent viral disease that kills a large percentage of those infected. It has no cure and an origin has not been found.
