coagulase. a bacterial enzyme that reacts with a cofactor found in blood plasma to catalyze the formation of fibrin from fibrinogen. It is produced by most of the virulent strains of staphylococci, and by Yersinia pestis.nzymatic conversion of fibrinogen in rabbit plasma to fibrin is used as a means of identifying pathogenic species of staphylococci. The test may be carried out rapidly on a slide or in several hours or overnight in a tube. Most coagulase-positive staphyloccoci are pathogenic; coagulase-negative ones commonly are not.
Asexual reproduction is an advantage in a stable environment. This is because it produces offspring genetically identical to the parent which is already well adapted and suited to the environment.
Best Answer: Sexual reproduction allows traits that are adaptive/beneficial to spread through a population and species fairly quickly.It also allows 2 or more beneficial traits that have evolved independently in 2 or more individuals to be passed along to the same descendants.exual reproduction also promotes genetic diversity, so that a population is less susceptible in case of disease epidemics. For example, when the plague hit Europe, some individuals by chance had mutations that allowed them to survive, and they did.
