A list of aggrecultural project in minimum space
Most of the agrecultural project required big space. Big space occupied agriculture project obviously provide you big earning. But it is costly matter.
Some common types of aggrecultural project that you can operate from a small range of space and even with low cost.
Apiculture
Cultivation of bees. Cultivation of bees can give you big earning from small scale space. It is too much cost effective.
Mashroom
Mashroom cultivation is another types of aggrecultural project that can operate from small scale space.

Heredity
Heredity means the transfer of characteristics of organism from the ancestor to offspring. The previous generation of any animals or plants is called the ancestor of this animals or plants.
In more biological term, heredity is gene transfer to generation to generation. Genetics is nothing but the study of heredity in biology.
Heredity can cause through both asexual reproduction or sexual reproduction.
Let us think about the brown color hair of an individual is gained form the previous generation is a trait of human being. This trait is completely depends on the gene structure. A complete set of gene in genome is called genotype.
We sometime make complexity between genotype and phenotype. Phenotype is the complete set of observable trait of organism that exactly depends on the environmental exposure of organism and any structural change in organism is not the gene function rather it an environmental function.
DNA elaborately says Di-Oxyribonucleic acid is a molecule through which genetical information transfer from generation to generation.

Evolution
Evolution is a process of change in generation to generation heritable characteristics. One of the visual results of evolution is biodiversity in world.
Due to a long evolutionary process, speciation and extinction of population member happens. Speciation is formation of new species and extinction is loss of any species.
In phylogenetics there found extra-ordinary relationship of existing species with extinct species.
At first Charls Darween discover the evolutionary theory by natural selection process in his book Origin of species.
The process of changing of gene to gene is called evolutionary mechanism. Evolutionary mechanism may be in four kinds.
Sexual selection
Genetic drift
genetic mutation
Gene migration

Mitosis cell division
Mitosis is a process of cell division in higher class of animals and plants. Growth is a normal physiological process in life. Hence, cell division is mandatory to grow up. There have certain types of cell division.
Amitosis
Mitosis
Meiosis
In mitosis cell division one mother cell divides equally into two daughter cell. The properties of daughter cell is as same as the properties of mother cell. Here, mother cell is the cell that undergo into cell division to produce new daughter cell.
Mitosis cell division happens through Five steps
Prophase
Pro-metaphase
Metaphase
Anaphase
Teluphase

DNA Replication
The term replication in genetics is meant somewhat with the word reformation. Hence, DNA replication means the reformation of DNA during cell division.
Cell division is a normal physiological process in every plant and animal. The higher class of animal and plant undergo into Mitosis cell division, where lower class living organ such as bacteria undergo into amitosis cell division. Meiosis is another special types of cell division that occurs in reproductive cell.
During cell division nucleus have to divide and daughter cell nucleus would be same properties with mother cell.
Division of nucleus start with the breaking down of double helix DNA into single helix. Each single helix made copy of itself and than again recoiled and form DNA. This is called DNA replication.
