Cacti are native to deserts in the Americas, whereas cactus-like euphorbs are native to African deserts. The two plant groups ar
e not closely related, and the euphorbs have normal broad-leaved plants such as the Christmas poinsettia in their ancestry. The most likely explanation for the similarity of some euphorbs to cacti is __________.
The convergent evolution is a process by which the unrelated or not closely related organisms independently evolve with same traits as a result of being exposed to the same kind of environment or having the same ecological niches. These organisms are linked due to common ancestry.
The given situation is the example of convergent evolution, this is because of the fact that both species (Cacti and cactus-like euphorbs) are native plants of different countries. These species are not closely related but they are sharing common ancestral characteristic with Christmas poinsettia.
These molecules need to pass through specific proteins or transmembrane proteins embedded in the cell membrane. A specific type of an integral membrane protein.
