Difference Between O Positive and O Negative
The key difference between O positive and O negative blood group is that the O positive blood has Rh factor in their red blood cell membranes while the O negative blood does not have Rh factor. Human blood can be classified into four different types of groups according to the antigen in the cell surface […]
Difference Between Protostomes and Deuterostomes
The key difference between Protostomes and Deuterostomes is that in protostomes blastopore becomes the mouth while in deuterostomes it becomes the anus. Another major difference is that embryos of protostomes undergo spiral cleavage while embryos of deuterostomes undergo radial cleavage. In understanding these two terms it would be important to pay attention to how the […]
Difference Between Flea and Tick
Flea vs Tick Fleas and ticks are external parasites of many types of hosts, yet there are significant differences between them. Taxonomy, anatomy, and morphology would be important to consider in differentiating the two groups. They both can cause deadly diseases to their hosts, but the range of diseases varies between fleas and ticks. […]
Difference Between Amoeba and Paramecium
The key difference between amoeba and paramecium is that the amoeba moves using pseudopodia while the paramecium moves using cilia. Amoeba and paramecium are two very important unicellular eukaryotes. They are protozoans belonging to kingdom Protista. They live in aquatic environments, and they are heterotrophs. Both amoeba and paramecium are motile. They move using two […]
Difference Between Blood and Plasma
Blood vs Plasma In many multicellular organisms, oxygen obtained by the respiratory system and nutrients processed by the digestive system are distributed by the circulatory system. The circulatory system is also responsible for removal of carbon dioxide and other waste products within the body cells. All multicellular organisms have a heart that pumps particular […]
Difference Between Humoral and Cell Mediated Immunity
The key difference between humoral and cell mediated immunity is that the humoral immunity (antibody-mediated immunity) involves antibodies while the cell mediated immunity does not involve antibodies. Immunity is the ability of an organism to defend against pathogens and toxins and to avoid infections and diseases. Therefore, the immune system is the tissue system that […]
Difference Between Adult and Embryonic Stem Cells
The key difference between adult and embryonic stem cells is that adult stem cells are multipotent while embryonic stem cells are pluripotent. Stem cells are a category of cells with the ability to divide and develop into different types of cells in the body. They are distinguished from the normal cells since they divide and […]
Difference Between Ventilation and Respiration
Ventilation vs Respiration The respiratory and cardiovascular systems work together to ensure a constant supply of essential oxygen to every cell in the body and also the removal of carbon dioxide and other waste products from every cell. Both ventilation and respiration processes come under the respiratory system associated with the lungs and are […]
Difference Between Equal and Equivalent
Equal vs Equivalent Equal and equivalent are terms or words that confuse many not having a math background. This is because those having studied sets in math know that equivalent does not mean identical or the same. There are similarities between things or objects that are equivalent. However, it would be wrong to Say […]
