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.
Bilateral nervous systems, the simplest of which occur in flatworms, represent a distinct increase in complexity over the nerve net of radiate animals.
Microorganisms isolated from different sources (soil, water and air) or genetic manipulation are cultured on growth media.
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.
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

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?
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.
Biotechnology can be seen as an imprecise term since the harnessing of any biological process could justifiably be called biotechnology.
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.
Structural bioinformatics is concerned with computational approaches to predict and analyse the spatial structure of proteins and nucleic acids.
A tissue is a group of similar cells (together with associated cell products) specialized for the performance of a common function.

Horticulture may be described as the practice of growing plants in a relatively intensive manner. This contrasts with agriculture, which, in most Western European countries, relies on a high level of machinery use over an extensive area of land
Process by which an early metazoan embryo becomes a gastrula, acquiring first two and then three layers of cells.
Column chromatography is one of many forms of chromatography. Others include paper, thin-layer, gas, and HPLC. Most forms of chromatography use a 2-phase system to separate substances on the basis of some physical-chemical property.
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
