Any plant containing a system of vessels which transport water and nutrients between different parts of the plant (e.g., from the roots to the leaves) .
Industry:Natural environment
Electromagnetic radiation with wavelengths from just longer than the visible (about 0.7 micrometers) to about two micrometers.
Industry:Natural environment
Obligate or required. For example, an obligatory cleaner fish relies entirely on this feeding mode to obtain nutrients; opposite of facultative.
Industry:Natural environment
Relating to the sagittal plane, which extends through the midline of a bilateral animal, dividing it into two equal halves.
Industry:Natural environment
The chronological series of changes, from a lower to a higher state of organization, which multicellular organisms undergo from the fertilized egg (zygote) to maturity.
Industry:Natural environment
The metabolic processes that consumes energy and involve the synthesis of larger, complex molecules from simpler ones.
Industry:Natural environment
The situation where a diver is at a depth or pressure for a long enough period of time (12 hours or longer) to have the partial pressures of the dissolved gases in the body at equilibrium with the partial pressure of the gases in the surrounding environment. Scientists are able to live in and work around underwater habitats for extended periods without the risk of developing decompression sickness (the bends). Divers breathe compressed air mixed with light, inert gases, such as helium. When the diver's blood becomes saturated with helium, the time required for decompression, even if the diver returns to the surface after a period of weeks, is no greater than that required after a dive lasting just a few hours.
Industry:Natural environment
A bluish, copper-containing respiratory pigment with an oxygen-carrying function similar to that of hemoglobin that is present in the blood of certain mollusks and arthropods.
