Packed inside an insect no bigger than a jellybean is a venom strong enough to cause intense pain in humans - and occasionally death, in people who are allergic to it.
To protect food quality and safety, antioxidants are often added to processed foods. These antioxidants can be synthetically derived compounds, such as butylated hydroxytoluene and ethylene diaminetetraacetic acid.
Most insects? tough exoskeletons protect their bodies from predators and from drying out. however, some insects?including young insects, such as caterpillars - have soft bodies. they benefit by adding an extra layer of protective armor.
Alkaloids are classified according to the amino acid that provides both the nitrogen atom and the fundamental portion of the alkaloid skeleton, and these are discussed in turn.
Atoms of certain metals will absorb and emit radiation of specific wavelengths when heated in a flame, in direct proportion to the number of atoms present.
Germplasm theory of Weismann was a very significant advancement in our understanding of heredity, since this was for the first time that a distinction between hereditary and environmental variations could be made on a sound basis.
Among all living organisms, flowers, which are the reproductive structures of angiosperms, are the most varied physically and show the greatest diversity in methods of reproduction of all biological systems.
Microorganisms isolated from different sources (soil, water and air) or genetic manipulation are cultured on growth media.
The most important areas of today's research which have potential economic value and prospects of commercialization are the cell and tissue culture based production of vaccines, monoclonal antibodies, pharmaceutical drugs, cancer research, genetic manipul
The biosphere as usually defined is the thin outer layer of the earth capable of supporting life. It is probably best viewed as a global system that includes all life on earth and the physical environments in which living organisms exist and interact.
Microalgae and macroalgae have been utilized by man for hundreds of years as food, fodder, remedies, and fertilizers. Ancient records show that people collected macroalgae for food as long as 500 B.C. in China and one thousand of years later in Europe.
Protiens are polymers of amino acids joined by peptide bonds (proteins are therefore also known as polypeptides). The number and order of the amino acids contained in a particular protein are prescribed by the DNA sequence of that protein?s gene.
The area of developmental genetics has also received major attention of geneticists in recent years to answer questions like the following. What are the relative roles of nucleus and cytoplasm in differentiation?
Coenzymes are small organic molecules that function with thousands of different enzymes in all organisms, assisting in the catalytic processes needed for life. They often contain vitamins as components.
Structural bioinformatics is concerned with computational approaches to predict and analyse the spatial structure of proteins and nucleic acids.
A biome is a major biotic unit bearing a characteristic and easily recognized array of plant life. Botanists long ago recognized that the terrestrial environment of the earth could be divided into large units having a distinctive vegetation, such as fores
