Answer: (B) Archaebacteria
Explanation: Archaebacteria, like all prokaryotes, have no membrane bound organelles. This means that the archaebacteria are without nuclei, mitochondria, endoplasmic reticula, lysosomes, Golgi complexes, or chloroplasts. Because<u> these organisms have no nucleus</u>, the genetic material floats freely in the cytoplasm.
<h3><u>Answer;</u></h3>
He crossed two pure breeds
<h3><u>Explanation;</u></h3>
- <em><u>F1 or the first filial generation is the first generation of offspring produced by crossing a set of parents to help show what genes will be inherited from crossing pea plants. Therefore, the F1 generation consist of or offspring from the parents.</u></em>
- <em><u>Mendel performed a true breeding cross, meaning he crossed one homozygous recessive for a trait and one homozygous dominant for the trait. This gave rise to the heterozygous dominant offspring. </u></em>

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!
