Many prokaryotes are adapted to live inside the body because the majority of bacteria are mesophilic.
Depending on the optimal temperature of development, there are three types of bacteria:
* Mesophilic bacteria prefer average temperatures between 20 and 40 ° C. The majority of bacteria is mesophilic. This is the case of pathogenic bacteria of man and animals, but also commensal bacteria of natural cavities, cutaneo-mucous membranes and especially saprophytic environmental bacteria involved in the degradation and recycling of dead organic matter. (necromass).
* The psychrophilic bacteria have an optimal temperature of development close to 0 ° C.
* Thermophilic bacteria can live at high temperatures (45 ° C in hot springs).
Answer:

Answer:
Melanin is responsible for black colour of hair.
Explanation:
Hair is black in colour because it is determined by the amount of a pigment present in hair is called melanin. If eumelanin which is a type of melanin, present in hair, it gives people black or brown hair. If the receptor is not activated or is blocked in the hair, then melanocytes make pheomelanin instead of eumelanin and then the black or brown hair colour did not occurs so we can conclude that melanin is responsible for black colour of hair.
