Answer:
b. the new species must be unable to breed with the original species.
Explanation:
By definition, species are defined as groups of similar organisms that can live and breed freely. This means that individuals in that species can interbreed and produce viable, fertile offspring. However, two different species cannot interbreed to produce fertile offspring due to biological barriers known as mechanisms of reproduction isolation.
These barriers are broadly classified as pre and postzygotic. Prezygotic barriers include the following:
- Habitat isolation: Two species occupy entirely different and distant habitats.
- Temporal isolation: Two species procreate at different times of the year.
- Behavioral isolation: Two species exhibit different mating behaviors.
- Gametic isolation: The gametes of the two species cannot fertilize.
- Mechanical isolation
Speciation, the production of an entirely new species, requires a maintenance of genetic diversity. Therefore, the new and original species cannot interbreed as this would limit the gene pool and decrease genetic variations.
Enzymes reduce the activation energy allowing chemical reactions to occur in living things.
The archaea are in a different domain from bacteria due to certain differences in their morphology and habitats, the Archaea are the separate domain of life in prokaryotes. For example; unlike bacteria, archaea cell walls do not contain peptidoglycan, they have different membrane lipid bonding from bacteria and eukarya.
Archaea is considered as the different domain of life in prokaryotes, as they are the most primitive type and known as the ancient microbes found in extreme niches such as hydrothermal vents, higher salt concentration, high temperature, and pressure etc
