Biology is the study of living organisms. Biology includes many sub-disciplines, such as microbiology and biochemistry. Microbiology studies microorganisms, while biochemistry studies the building blocks that compose organisms. Although distinct areas of biology, the two share many attributes. The...

Organic chemistry is that branch of chemistry that deals with the structure, properties, and reactions of compounds that contain carbon. It is a highly creative science. Chemists in general and organic chemists in particular can create new molecules never before proposed which, if carefully designed,...

Rural development is a strategy designed to improve the economic and social life of a specific group of people the rural poor. From the very dawn of freedom struggle, the socio-economic transformation of the rural masses has been the focal point of all the developmental efforts. Following the political...

Sustainable agriculture can feed the world without damaging the environment or threatening human health. It is a way of growing food in an ecologically and ethically responsible manner. Sustainable crop production practices can lead to higher yields over time, with less need for expensive and environmentally...

Conventional agriculture has attempted to exploit arable land by applying chemical fertilizers, pesticides, and irrigation water. These practices become increasingly tenuous as they exhaust our supplies of fossil fuels, deplete aquifers and raise concerns about the safety of food and the overall effect...

Weed management is most successful when it involves an integrated approach using a variety of methods. The common methods used to manage weeds include prevention and cultural, mechanical, biological, and chemical means. Preventative methods are used to stop the spread of weeds. Preventing the introduction...

Adventure tourism is a complex industry with a wide variety of elements and suppliers. Some of these suppliers are also part of the mainstream tourism industry such as accommodation operators while others are specific to adventure tourism like equipment manufactures. The growth of adventure tourism...

A branch of genetics that studies heredity and variation chiefly in farm animals but also in domestic and wild animals. It is based on general genetic principles and concepts, and it mainly uses the hybrid, cytological, population, ontogenetic, mathematical-statistical, and twin methods of general...

A seed is a small embryonic plant enclosed in a covering called the seed coat, usually with some stored food. It is the product of the ripened ovule of gymnosperm and angiosperm plants which occurs after fertilization and some growth within the mother plant. The formation of the seed completes...

The study of nematode biology has led to a dramatic increase in understanding of how all animals function. In fact, the bacterial-feeding nematode, Caenorhabditiselegans, is one of the best-understood animals on earth. The fate of every cell in C. elegans development has been carefully mapped. It...

Knowledge in microbiology is growing exponentially through the determinationof genomic sequences of hundreds of microorganisms and the invention of newtechnologies, such as genomics, transcriptomics, and proteomics, to deal with this avalanche of information. These genomic data are now exploited in...

Animals and bacteria have cell surface antigens referred to as a blood type. Antigens from the human ABO blood group system are also found in apes such as chimpanzees, bonobos and gorillas. Other animal blood sometimes agglutinates (to varying levels of intensity) with human blood group reagents,...

Dairy farming has been part of agriculture for thousands of years. Historically it has been one part of small, diverse farms. In the last century or so larger farms doing only dairy production have emerged. Large scale dairy farming is only viable where either a large amount of milk is required for...
