Based on his observations on monohybrid crosses Mendel proposed two general rules to consolidate his understanding of inheritance in monohybrid crosses. Today these rules are called the Principles or Laws of Inheritance: the First Law or Law of Dominance and the Second Law or Law of Segregation. Law of Dominance Characters are controlled by discrete … Read more

The lymphatic system has three primary functions: Fluid balance The lymphatic system helps maintain fluid balance. It returns excess fluid and proteins from the tissues that cannot be returned through the blood vessels.  The fluid is found in tissue spaces and cavities, in the tiny spaces surrounding cells, known as the interstitial spaces. These are … Read more

The circulatory system consists of three independent systems that work together: the heart (cardiovascular), lungs (pulmonary), and arteries, veins, coronary and portal vessels (systemic). The system is responsible for the flow of blood, nutrients, oxygen and other gases, and as well as hormones to and from cells. An average adult has 5 to 6 quarts … Read more

The endocrine system is made up of the endocrine glands that secrete hormones. Although there are eight major endocrine glands scattered throughout the body, they are still considered to be one system because they have similar functions, similar mechanisms of influence, and many important interrelationships.   Glands Feature   Pituitary Gland It is the endocrine … Read more

Composting is an anaerobic microbially driven process that converts organic wastes into stable sanitary humus like material. This material can then be safely returned to the natural environment. This method is actually a low moisture, solid substrate fermentation process. In large- scale operations using largely domestic solid wastes, the final product is mostly used for … Read more

. India is at the learning stage for many of the complex technologies required to create a BMD system. DRDO’s record in producing weapon systems has not been encouraging as exemplified by the delayed induction of the LCA, the failure of the Arjun MBT and the virtual rejection of the INSAS rifle by the Indian … Read more

Type 1: Reactive Machines. An example is Deep Blue, an IBM chess program that can identify pieces on the chess board and can make predictions accordingly. But the major fault with this is that it has no memory and cannot use past experiences to inform future ones. It also analyzes possible moves of its own … Read more

Genetic engineering Scientists have learned how to move genes from one organism to another. This has been called genetic modification (GM), genetic engineering (GE) or genetic improvement (GI). Regardless of the name, the process allows the transfer of useful characteristics (such as resistance to a disease) into a plant, animal or microorganism by inserting genes … Read more

Nanotechnology relates to the technology of rearranging and processing of atoms and molecules to fabricate material to Nano specifications such as nano meters, the technology will enable scientist and engineers to see and manipulate matter at the molecular level atom by atom create new structure with fundamentally new molecular organic material and exploit the novel … Read more
