Sharks, whales, and dolphins share similar features such as body shape and the position of fins. However, sharks have gills for breathing, while whales and dolphins have lungs. Sharks and dolphins are similar in construction because they need their parts to complete many of same functions.
For example:
The dorsal fins that are found in both shark and dolphin are due to convergent evolution and they are actually not from common ancestor.

By definition, animal cells have no cell wall -- only plant cells do. That being said, the major function of the cell wall in plant cells is to control cell pressure<span> due to …the influx and exit of water into and out of the cell. hope that helped</span>
The answer is <span>geographic isolation.</span>
<span>When a new species form by geographic isolation, it is called
geographical speciation or allopatric speciation. Geographical isolation is a physical separation which prevents gene
flow between distinct populations (on the island and on continent). The island populations will eventually diverge from a single species that migrated to the island. The members of the populations, which once belonged to the same species, will
no longer be able to mate and produce offspring. Eventually, the formation
of new species will occur, for example kangaroos, koala, and wombats, form that one species.</span>
The general function of lactase is to regulate cell processes. It is an enzyme, and enzymes act as catalysts of chemical reactions within the body. It regulates different chemical reactions including breakdown of food substances, etc.
