Although the terms erosion and denudation are used interchangeably, erosion is the transport of soil and rocks from one location to another, [1] and denudation is the sum of processes, including erosion, that result in the lowering of Earth's surface. [2] Endogenous processes such as volcanoes, earthquakes, and tectonic uplift can expose ...
For example, endogenous substances, and endogenous processes are those that originate within a living system (e.g. an organism or a cell). For instance, estradiol is an endogenous estrogen hormone produced within the body, whereas ethinylestradiol is an exogenous synthetic estrogen, commonly used in birth control pills .
Developmental bioelectricity is a sub-discipline of biology, related to, but distinct from, neurophysiology and bioelectromagnetics.Developmental bioelectricity refers to the endogenous ion fluxes, transmembrane and transepithelial voltage gradients, and electric currents and fields produced and sustained in living cells and tissues.
Surficial processes are the physical and chemical phenomena which cause concentration of ore material within the regolith, generally by the action of the environment. This includes placer deposits, laterite deposits, and residual or eluvial deposits. Superficial deposits processes of ore formation include; Erosion of non-ore material.
A general name for this class of material is biological materials. Biomolecules are an important element of living organisms. Biomolecules are an important element of living organisms. They are often endogenous , [ 2 ] i.e. produced within the organism, [ 3 ] but organisms usually also need exogenous biomolecules, for example certain nutrients ...
Instead, they replicate via binary fission, a replication process uncoupled from the host cells in which they reside. [ 10 ] [ 11 ] Some human parasites, e.g. Wuchereria bancrofti and Mansonella perstans , thrive in their intermediate insect hosts because of an obligate endosymbiosis with Wolbachia spp. [ 12 ] They can both be eliminated by ...
The history of life on Earth traces the processes by which living and extinct organisms evolved, from the earliest emergence of life to the present day. Earth formed about 4.5 billion years ago (abbreviated as Ga, for gigaannum) and evidence suggests that life emerged prior to 3.7 Ga. [1] [2] [3] The similarities among all known present-day species indicate that they have diverged through the ...
There are exogenous processes and endogenous processes. Endogenous is a process that develops as a part of species biology so they typically include changes in biology, behavior, and interactions within or between species. Endogenous threats can result in changes to breeding patterns or migration patterns and are often triggered by exogenous ...
