Hi
Before answering this question, we need to understand first that what a mutation is. <em>A mutation basically is a change in the DNA or genetic sequence of an organism that can significantly affect or not affect the function of a specific gene in organism. </em>
Now coming towards the question, yes ofcourse it is possible that a Norwar rats population carries a different genetic mutation than a population os same rats in Africa or any other region, Why? Because sometimes environmental factors of a certain area can cause the population of a region to undergo mutation (For example harsh UV rays) and the other population donot contains that mutation. This will cause a slight change in the genetic makeup of the population of rats of Norther America. However, if the changes in genetic makeup continues to happen in North American Norway rats, a time will come when they will be genetically very different from same rats in Africa and in this way they will become a separate or different specie, this phenomenon is called speciation.
Hope it helps!
Answer:
Fossils of mollusks would be found in lower strata than that of arthropods
Explanation:
Fossils are found in different layers of sedimentary rocks. The fossils of organisms that evolved earlier are found in the lower strata while those evolved later are preserved as fossils in the upper strata. If mollusks evolved before arthropods, fossils of arthropods would be present in upper layers while those of mollusks would be found in deeper layers.

Answer:
The correct answer is - regulation of the heavy metal and their toxicity.
Explanation:
Metallothionein is a group of cysteine-rich, small in size, and highly conserved proteins that bind to various metal ions and regulate their activity or toxicity in transcriptional level.
Metallothionein IIA is one of the metallothioneins that binds to heavy metal and helps cells to be protected from the toxicity of these heavy metals. These proteins are present in almost every eukaryotic organisms virtually. These proteins are highly induced to express highly in the present of heavy metals.
Thus, the correct answer is - regulation of the heavy metal and their toxicity.
The process that is similar to binary fission is Mitosis
