21) B. They reproduce by binary fission. Biological species concept does not apply to organisms that reproduce asexually, such as prokaryotes.
22) C. Temporal isolation. It is a type of prezygotic isolating meachanisms where species breed at different times
23) C. Mechanical and temporal isolation. Prezygotic isolating meachanisms lead to reproductive isolation by preventing the formation of hybrid zygptes. This is attained by ecological isolation (species occupy different habitats), Temporal isolation (species breed at different times); behavioral isolation (species engage in distinct courtship and mating rituals) and mechanical isolation (Blockage in the formation of zygote, inability of sperm to bind to egg)
