An example of ecological recycling occurs in the enzymatic digestion of cellulose. "Cellulose, one of the most abundant organic compounds on Earth, is the major polysaccharide in plants where it is part of the cell walls. Cellulose-degrading enzymes participate in the natural, ecological recycling of plant material."
In biology, a biological life cycle (or just life cycle when the biological context is clear) is a series of stages of the life of an organism, that begins as a zygote, often in an egg, and concludes as an adult that reproduces, producing an offspring in the form of a new zygote which then itself goes through the same series of stages, the ...
A cycle track or cycleway (British) or bikeway [1] (mainly North American), sometimes historically [2] referred to as a sidepath, is a separate route for cycles and not motor vehicles. In some cases cycle tracks are also used by other users such as pedestrians and horse riders (see shared-use route ).
Examples of exchange pools include plants and animals. [23] Plants and animals utilize carbon to produce carbohydrates, fats, and proteins, which can then be used to build their internal structures or to obtain energy. Plants and animals temporarily use carbon in their systems and then release it back into the air or surrounding medium.
Photoheterotrophs generate ATP using light, in one of two ways: [6] [7] they use a bacteriochlorophyll-based reaction center, or they use a bacteriorhodopsin.The chlorophyll-based mechanism is similar to that used in photosynthesis, where light excites the molecules in a reaction center and causes a flow of electrons through an electron transport chain (ETS).
Deputy Editor Tara Seplavy chats with 3x Olympian Bobby Lea to learn about the fast-paced disciplines of Olympic track cycling, track bikes, and training tips.
The zone between black and red lines is sprinter's lane, which is the optimum route around the track. A rider leading in the sprinter's lane may not be passed on the inside; other riders must pass on the longer outside route. Minimum 2.5 metres (8.2 ft) (or half the track width) above the inside of the track is the blue stayer's line.
Biological processes are regulated by many means; examples include the control of gene expression, protein modification or interaction with a protein or substrate molecule. Homeostasis: regulation of the internal environment to maintain a constant state; for example, sweating to reduce temperature
