organ donation forms

Acid-base reactions according to this concept involve donation of electron pair by a base to an acid to form a co-ordinate bond. Lewis bases can be neutral molecules such as the ones shown below: These have one or more unshared pair/s of electrons or anions such as C..

Two or more individuals with identical genetic make up formed from one parent by asexual reproduction are called clones. For example, daughter plants produced by strawberry runners and whole plants produced by tissue culture are clones. Similarly, the individuals formed by..

Chemical evolution resulted in the formation of life on earth about 3.8 billion years ago. The primitive cells that resulted from this process gradually gave rise to primitive forms of organisms such as bacteria, algae, fungi and protozoan. These organisms in tur..

Evolution may be defined as a gradual development of more complex species from pre-existing simpler forms. It is an extremely slow process and has occurred over millions of years. Evolution that has occurred is clear because of the evidences of fossils, etc. However, the mechanism o..
