Systemic.Cell Theory is one of the basic principles of biology. Credit for the formulation of this theory is given to German scientists Theodor Schwann (1810-1882), Matthias Schleiden (1804-1881), and Rudolph Virchow (1821-1902). The Cell Theory states: All living organisms are composed of cells. They may be unicellular or multicellular.1. Define the word "Heredity".

It is defined as the phenomenon that transfers genetic information from a parent to their offspring. Some of the heredity examples can be given as; if a child is left-handed then there ...Biology is the scientific study of life. It is a natural science with a broad scope but has several unifying themes that tie it together as a single, coherent field.
