A coal mine in Wyoming, United States. Coal, produced over millions of years, is a finite and non-renewable resource on a human time scale.. A non-renewable resource (also called a finite resource) is a natural resource that cannot be readily replaced by natural means at a pace quick enough to keep up with consumption. [1]
The green box (central) may represent an evolutionary grade (paraphyletic), a group united by conservative anatomical and physiological traits rather than phylogeny. The flanking red and blue boxes are clades (i.e., complete monophyletic subtrees). A grade is a taxon united by a level of morphological or physiological complexity.
Nonfinite is the opposite of finite a nonfinite verb is a verb that is not capable of serving as the main verb in an independent clause a non-finite clause is a clause whose main verb is non-finite
While the probability of encountering food, potential sexual partners, or predators is the same in all directions for animals floating freely in the water, there is a clear difference on the seafloor between the functions useful on body sides facing toward and away from the substrate, leading their sensory, defensive, and food-gathering cells ...
There are structural differences between the limb anatomy of plantigrades, unguligrades, and digitigrades. Digitigrade and unguligrade animals have relatively long carpals and tarsals, and the bones which correspond to the human ankle are thus set much higher in the limb than in a human. In a digitigrade animal, this effectively lengthens the ...
Examples of precocial birds include the domestic chicken, many species of ducks and geese, waders, rails, and the hoatzin. Precocial birds can provide protein-rich eggs and thus their young hatch in the fledgling stage – able to protect themselves from predators and the females have less post-natal involvement.
Hyenas are large, powerful animals, up to 80 kg (176 lb) and represent one of the most prolific large carnivorans on the planet. The aardwolf is much smaller and is a specialised feeder, eating mainly harvester termites. Family Herpestidae (mongooses, kusimanses, and the meerkat) has 32 species. Previously, these were placed in the family ...
Extant primates exhibit a broad range of variation in sexual size dimorphism (SSD), or sexual divergence in body size. [4] It ranges from species such as gibbons and strepsirrhines (including Madagascar's lemurs) in which males and females have almost the same body sizes to species such as chimpanzees and bonobos in which males' body sizes are larger than females' body sizes.
