Answer: Very unlikely
Explanation:
Generally, point mutation can be easily reversed by another point mutation, so
before any changes occur in the amino acid sequence, it would have been corrected.
However, when point mutation occurs within the protein coding region of a gene it may results in the change of a single nucleotide to cause the substitution of a different amino acid (which renders the protein non-functional) as in the case of sickle-cell disease.
And this kind of point mutation is specifically called Missense mutation.
Above all, because point mutation is easily reversible, it is very unlikely to change the amino acid sequence of a protein
The statement 'Islands are often isolated, minimizing gene flow and maximizing diversification' explains why islands may have unique species on Earth.
<h3>What is isolation?</h3>
Isolation refers to the absence of gene flow between individuals of the same species for extended periods of time.
Isolation due to geographic barriers (e.g., a island) may led to reproductive differentiation and even to speciation.
In conclusion, the statement 'Islands are often isolated, minimizing gene flow and maximizing diversification' explains why islands may have unique species on Earth.

Answer:
A bacterial cell is a prokaryotic cell. Animal cells are eukaryotic cells.
Explanation:
ANIMAL CELLS: They are the basic unit of life of organisms which belong to kingdom Animalia. They have a well-defined membrane-bound nucleus, cytoplasm surrounded by plasma membrane and membrane-bound cell organelles in the cytoplasm to perform specific cellular functions necessary for the normal functioning of the cell. They can be of various sizes and shapes. Their size generally ranges between 1 and 100 micrometers.
BACTERERIAL CELLS: It is a simple, unicellular microorganism which means all life processes like feeding, digestion, and reproduction occur in one cell. It lacks the membrane-bound nucleus and organelles like mitochondria, lysosomes and other specialized cellular structures to perform cellular functions like energy production, transport of proteins etc. The cell wall of the bacterial cell is made up of glycoprotein, murein. Its main function is to provide support, mechanical strength and rigidity to the bacterial cell
