Answer:
Frogs reproducesexually and when organisisms reproduce sexually there are benefits which include:
produces genetic variation in the offspring.
the species can adapt to new environments due to variation, which gives them a survival advantage.
a disease is less likely to affect all the individuals in a population.
A disadvantage is that sexual reproduction takes longer than asexual reproduction. A mate must be found, the egg must be fertilised by sperm, and then the offspring develop. The benefit of introducing genetic variation into the species , however, outweighs this disadvantage.
