Electrolytes :- Electrolytes are substances that produce an electrically conducting solution when dissolved in a polar solvent , such as water . The dissolved electrolytes separates into cations and anions , which disperse uniformly through the solvent . Examples – NaCl , HCl , H₂SO₄ , HNO₃ , CaCl₂ , NaOH , CH₃COOH , KNO₃…
Population :- A population may be defined as a group of organisms of the same species occupying a certain area or space at a given time . The term interbreeding implies sexual reproduction , a group of individuals resulting from even asexual reproduction is also generally considered a population for the purpose of ecological studies…
Biodiversity :- Biodiversity is the term popularised by the sociologist Edward Wilson to describe the combined diversity at all the levels of biological organisation . The most important of biodiversity are – 1 . Genetic diversity :- A Single species might show high diversity at the genetic level over its distributional range . The genetic…
Ecosystem :- An Ecosystem can be visualised as a functional unit of nature , where living organisms interact among themselves and also with the surrounding physical environment . Components of an Ecosystem :- 1 . Biotic components . 2 . Abiotic components . Biotic components :- Biotic components are living things that shapes an Ecosystem…
Microbes in Human Welfare :- Microbes are the major components of biological Systems on this earth . Microbes like bacteria and many fungi can be grown on nutritive media to form colonies , that can be seen with the naked eyes . Such culture are useful in studies on micro-organisms . Microbes causes disease in…
Applications of Biotechnology :- Applications of Biotechnology in – 1 . Alcohol production . 2 . Dairy products formation . 3 . Organic acids formation . 4 . Enzymes production . 5 . Vitamins production . 6 . Antibiotics production . 7 . Vaccines production . 8 . Hormones production . 9 . Recombinant DNA…
Biotechnology :- Biotechnology is recent branch of biology . Biotechnology deals with the techniques of using live organisms or enzymes from organisms to produce products and processes useful to humans . Principles of Biotechnology :- The two techniques are used for the development of modern Biotechnology . ( 1 ) Genetic Engineering :- This techniques…
Colligative Properties :- Colligative properties are properties of solutions that depends on the ratio of the number of solute particles to the number of solvent molecules in a solution and not on the nature of the chemical species present . All these colligative properties have the common characteristics that depend upon the number of Solute…
It is the homogeneous mixtures of two or more than two components . When the composition and properties are uniform throughout the mixture then it is called homogeneous mixture . It has following components – Solvent :- The component that present in the largest quantity is known as Solvent . Solvent can be solid ,…
Fertilization in Humans :- The Fertilization process was first study by Lillie in Echinoderms . Fertilization is the process in which male gamete and female gamete fuse together . In human being Fertilization takes place Fallopian tube between the two dissimilar gametes of the same Species . Fertilization may be external ( out side the…
Human Reproduction :- Human beings are nonseasonal breeders ,there is no Oestrus / heat . Male Reproductive System :- In human reproduction , The male Reproductive System Consists of paired testes , Several Accessory glands , a duct System and a mating Organ called the penis . Scrotum :- In man , both testes normally…
Development of Embryo in Flowering Plants :- Development of Embryo in Flowering Plants occur at the micropylar end of the embryo sac where the zygote is situated . Endosperm :- During the development of Embryo in Flowering Plants the primary endosperm cell divides repeatedly and form a triploid Endosperm tissue .The cells of this tissue…
