Answer:
Homology refers to the similarities between the group of species that share the common ancestor. The homology individuals arise from a common ancestor. They shows divergent evolution. The basic structure in homology is similar. The organs perform different function. They occur due to the evolutionary process.
Homoplasy refers to the shared characters of the group of species that do not share the common ancestor. The homoplasy do not involve the common ancestor. They shows convergent evolution. The basic structure in homoplasy is different. The organs perform the similar function. They occur due to the adaptation in different habitats.
<span>The site active of the enzyme bins the substrate to form the complex enzyme-substrate to start a specific chemical reaction. The site active of the enzyme has to fit exactly the shape of the substrate to trigger the catalysis.</span>
