Endemic species are those that are native to a particular area and are not found naturally anywhere else.

Fluidity refers to the ability of a fluid to flow easily.

Excitability refers to the ability of a muscle to respond to a stimulus, such as a nerve impulse.

Excitability refers to the ability of muscles to respond to stimuli, such as nerve impulses.

Biomagnification refers to the increasing concentration of harmful substances in organisms at each trophic level of the food chain.

Specific heat capacity is defined as the amount of heat required to raise the temperature of 1 kg of a substance by 1 degree Celsius.

Specific heat is defined as the amount of heat required to raise the temperature of a unit mass of a substance by one degree Celsius.

Humidity refers to the amount of water vapor present in the air.

A watershed is the area of land that drains water into a river, collecting precipitation and runoff.

Inflorescence refers to the arrangement of flowers on a stem.

Climate refers to the average weather conditions in a particular area over a long period, typically 30 years or more.

The boundary between two different air masses is called a front.

The term for the boundary between two tectonic plates is called a Plate boundary.

Hydrostatic pressure refers to the pressure exerted by a fluid at rest due to the weight of the fluid above it.

Condensation is the process where gas turns into liquid as it loses energy.

Evaporation is the process of changing from liquid to gas.

Freezing is the process where a liquid changes into a solid.

Sublimation is the process where a solid changes directly into a gas without passing through the liquid state.

Sublimation is the process where a solid changes directly into a gas without becoming a liquid.

Sublimation is the process where a solid changes directly into a gas.

The neuromuscular junction is the synapse between a motor neuron and a muscle fiber, facilitating muscle contraction.

Embryogenesis is the process of development of an organism from a fertilized egg.

Cytokinesis is the process that divides the cytoplasm of a parental cell into two daughter cells.

The energy required to change a substance from liquid to gas is called the latent heat of vaporization.

The heat of fusion is the energy required to change a substance from solid to liquid.

Surface tension is the energy required to increase the surface area of a liquid.

Ionization energy is defined as the energy required to remove an electron from an atom in the gas phase.

Desorption energy is the energy required to separate an adsorbate from an adsorbent.

Adaptive radiation is the evolutionary process where one ancestral species diversifies into multiple species to adapt to various environments.

Internal respiration refers to the exchange of gases between the blood and body cells, where oxygen is delivered and carbon dioxide is removed.
