The key difference between reptile and amphibian is that the reptile possesses a dry skin covered with hardened scales while the amphibian possesses a slime skin without scales. Kingdom Animalia includes eukaryotic, heterotrophic and mostly multicellular animals. There are two main groups of multicellular animals namely vertebrates and invertebrates. Vertebrates are the animals that possess […]
Difference Between Mammal and Reptile
The key difference between mammal and reptile is that mammal is a warm blooded vertebrate which can regulate the internal body temperature while reptile is a cold blooded vertebrate which cannot maintain constant body temperature. Vertebrates are animals that have a backbone or a vertebral column. They can be either warm blooded or cold blooded. Warm […]
Difference Between Mammal and Marsupial
The key difference between mammal and marsupial is that the mammal is a vertebrate which nourishes their young with milk produced inside the mammary glands of the mother while marsupial is a type of mammal which has a pouch to keep and nourish their undeveloped young ones. Mammal and marsupial belong to the same family […]
Difference Between Multicellular and Unicellular
The key difference between multicellular and unicellular is that multicellular organisms possess more than one cell while unicellular organisms possess only a single cell. Based on the cell number, there are two categories of organisms. Namely, they are unicellular and multicellular organisms. The behaviour, anatomy, and the functionalities of unicellular and multicellular organisms vary among […]
Difference Between Agar and Agarose
The key difference between agar and agarose is that the agar is a gelatinous substance obtained from red algae while the agarose is a linear polymer purified from agar or red seaweeds. Agar and agarose are two kinds of polysaccharide products that come from red algae or seaweed. They are very useful in a variety […]
Difference Between Tonicity and Osmolarity
The key difference between tonicity and osmolarity is that the tonicity measures only the concentration of non-penetrating solutes through a semipermeable membrane while the osmolarity measures the total concentration of penetrating and non-penetrating solutes. Osmolarity is the measure of osmotic pressure of a solution. In simpler terms, it is roughly the measure of the amount […]
Difference Between Bacteria and Viruses
The key difference between bacteria and viruses is that the bacteria can live without a host organism while the viruses cannot live without a living host. Many people think that both bacteria and viruses are germs that are harmful to human beings. Furthermore, they think that viruses and bacteria belong to the same category that […]
Difference Between Plants and Animals
The key difference between plants and animals is that the plants cannot move and they stay attached to the soil by roots while the animals can move from place to place. Also, the plants contain chloroplasts and chlorophylls but not the animals. Scientists tried to classify living organisms using different techniques. As a result, Robert […]
Difference Between a Ribonucleotide and a Deoxyribonucleotide
The key difference between a ribonucleotide and a deoxyribonucleotide is the sugar component of each nucleotide. Ribose is the sugar component of ribonucleotides while deoxyribose is the sugar component of deoxyribonucleotide. RNA and DNA are polymers of nucleotides; they are ribonucleotides and deoxyribonucleotides respectively. Though all human beings are alike in the sense that they […]
Difference Between Codominance and Incomplete Dominance
The key difference between codominance and incomplete dominance is based on the expression of the traits in the offspring. In Codominance, the offspring receive a combination of both parent genes, whereas, in Incomplete dominance, neither one of the parent genes expresses. In genetics, Gregor Mendel discovered the Principal of Dominance. But, it was found that […]
