Women synthesize several sex hormones including […]
Difference Between ICD and Pacemaker
The key difference between ICD and pacemaker is that ICD is an implantable device that sends out a shock when the heart beats way too fast rate while pacemaker is an implantable device that sends out electrical pulses when the heart beats way too slow. ICD (implantable cardioverter defibrillators) and pacemaker are two little implantable […]

Difference Between Open Circulatory System and Closed Circulatory System
The key difference between open circulatory system and closed circulatory system is that in open circulatory system, blood and interstitial fluid mix with each other while in closed circulatory system, blood and other fluids never mix with each other. Open circulatory system and closed circulatory system are two ways in which the circulatory system is […]
Difference Between Gene and Allele
The key difference between gene and allele is that the gene is a specific nucleotide sequence that encodes for a specific protein while the allele is a variant of a gene either the dominant or the recessive variant. A gene is the basic unit of heredity. Specifically, it has a precise nucleotide sequence that encodes […]
Difference Between Cell Wall and Cell Membrane
The key difference between cell wall and cell membrane is that the cell wall is a fully permeable cell layer present in bacteria, plants, fungi and algae while the cell membrane is a selectively permeable membrane present in all cell types including the animal cells. Cell membrane (plasma membrane) and cell wall are the outermost […]

They are very vital and useful decomposers in the environment […]
Difference Between Plant and Animal Cells
The key difference between plant and animal cells is that the plant cells have a cell wall composed of cellulose at the outside to the cell membrane while the animal cells lack a cell wall outer to the cell membrane. A cell is the fundamental unit of the living organisms. Some organisms are unicellular while […]
