Since there is a lot of diversity when dealing with life biologists classify organisms based on their characteristics. This is what is know as taxonomy. In short any living creature can be placed in a Domain, Kingdom, Phylum, Class, Order, Family, Genus and Species. For example a Panther would be classified as (in order) Eukarya, Animalia, Chordata, Mammmalia, Felidae, Panthera and Pardus. This tells us that the panther is an eukaryotic animal with a spinal chord that is a mammal in the cat family.

Biology is subdivided on the basis of levels that deal with basic units of life. Some branches of biology include botany, zoology, morphology and physiology.
The two main branches of biology are BOTANY (study of plants) and ZOOLOGY (study of animals).Although there have been discussions that there are actually three main branches of biology, this time including MICROBIOLOGY (study of microorganisms), but as far as it goes, botany and zoology are still the main branches of biology
The two main phases of cell division are mitosis and cytokinesis. Mitosis involves the division of the cell's nucleus into two identical daughter nuclei, while cytokinesis is the physical splitting of the cell into two separate daughter cells.
The vernier scale provides a more precise measurement by showing how much the object has moved past a whole number on the main scale. Since 4 divisions of the vernier scale coincide with one less division on the main scale, each division on the vernier scale represents 1/4 of a division on the main scale. In this case, the total reading would be 35 main scale divisions plus 4 divisions on the vernier scale, giving a total of 35.25 divisions on the main scale. To find the radius of the cylinder, you would measure the circumference with a tape measure or string and then divide that measurement by 2π to find the radius.
The two phases of the Cell Cycle are:InterphaseMitosis
mitosis, cytokinesisInterphase and Mitotic phase1.Prophase which is where the nuclear membrane dissolves. 2.Telophase which is where two new nucli form.
