They are like the lego blocks of life.
Many scientist studying organismal ecology focus on one aspect of the organism, such as its behavior or how it processes the nutrients of the enviorment.
Such organisms should be representative of the living beings for which they are to serve as proxy.

When viewed together, these eight characteristics serve to define life.
Understand how the role of cell organisation and different types of chemical reactions involved in maintaining high degree of internal order.
The word parasite comes from the Latin form of the Greek word παράσιτος (parasitos), meaning "one who eats at the table of another".
Heart, lung, brain, eyes, stomach, spleen, pancreas, kidney, liver, intestines, skin, urinary bladder, sex organs, and bones. Viruses are some ultra-microscopic entities, which multiply only after entering the cell of a specific living organism (Luria, 1953). What is Biology?

Reason: All the cells in the biological world are of same size. 1533 2. content • Introduction • Important yeast • Yeast as a model organism • Cloning in the yeast • Yeast E.coli shuttle vector • Yeast as expression vector • Yeast two hybrid system • Application of yeast two hybrid system • Conclusion • Refrence
Genetic recombination occurs naturally in meiosis.Meiosis is the process of cell division that occurs in eukaryotes, such as humans and other mammals, to produce offspring. Schistosoma eggs are eliminated with feces or urine, depending on species .Under appropriate conditions the eggs hatch and release miracidia , which swim and penetrate specific snail intermediate hosts .The stages in the snail include two generations of sporocysts and the production of cercariae .Upon release from the snail, the infective cercariae swim, penetrate the skin of the human host . Background: Model organisms are used for research because they provide a framework on which to develop and optimize methods that facilitate and standardize analysis. In 1784 W.SCHEELE's first time isolated from lemon juice as . 1.2.1 Fundamental Tenets of Molecular Biology. The central framework of molecular biology otherwise known as the "central dogma" is the starting point for the actual course of movement of genetic information within the cell's nucleus of an organism. You might expect more complex organisms to have progressively larger genomes, but eukaryotic genome size fails to correlate well with apparent complexity, and instead varies wildly over more than a 100,000-fold range.
Metabolism is the total amount of the biochemical reactions involved in maintaining the living condition of the cells in an organism. DNA I: The Genetic Material.

Life exists almost everywhere on the planet Earth.
The hormones are then secreted from the glands into the blood stream, where they are transported throughout the body. It is a biochemical process that occurs within the cells of organisms. Period 6 & 7 - Thurs April 18th. The transfer of genetic information within the cell of an organism (i.e. Size of bacteria range between 1 μm to 3 μm (smallest bacterium - Dialister pneumosintes (.15 m) (Largest bacterium is Spirillum volutans (13-15 m).

Each organism experiences a huge variety of interactions in its lifetime, and to study all of them is impossible. Even cells within the same organism show enormous diversity in size, shape, and internal organization. This process plays a major role in the development of humans and in developing and maintaining a healthy immune system.
It is a fastidious organism that exhibits narrow optical ranges of pH 7.2 to 7.4 and temperature 30 to 37°C. The outermost part of the cerebrum is a thick piece of nervous system tissue called the cerebral cortex, which is folded into hills called gyri (singular: gyrus) and valleys called sulci (singular: sulcus). Auxin Definition. clone, also spelled clon, cell or organism that is genetically identical to the original cell or organism from which it is derived.
