Explanation:
B)speciation
C)convergent selection
D)stabilizing selection
Answer:
B)speciation
Explanation:
Speciation is the term used to refer to the division of a lineage that produces two or more different species. In a nutshell, we can say that this is the process of the emergence of a new species, and the crucial event for this to happen is reproductive isolation. This reproductive isolation impedes the gene flow, therefore, obeying the biological concept of species, we say that a new species has emerged.
An example of speciation is shown in the question above, where a volcano separated two species and left them in reproductive isolation. The result of this was that two populations became so different from one another that they became unable to breed, creating new species.
B is the correct answer for e2020
B. ribosomes
C. mitochondria
Answer:
Option B, Ribosomes
Explanation:
Ribosome exists in both free state and also as a membrane bound organelle. Thus, ribosomes is found in both the eukaryotic and prokaryotic cells as it is an essential component that facilitates the translation of RNA and formation of protein.
Golgi apparatus and mitochondria are membrane-bound organelles and all membrane-bound organelles are found in eukaryotes only. Prokaryotes do not have membrane-bound organelles
Thus, option B is correct
