Answer:

e. horizontal transfer of genes from a marine bacterium

Explanation:

Horizontal gene transfer is the transfer of genetic material from one independent mature bacterium to another and creates new gene combinations in the recipient bacterium. It mostly occurs between the bacterial of different species and is responsible for the spread of new genetic traits such as antibiotic resistance, digestion of specific substances, virulence, etc.

Transfer of genetic material from the donor to host bacteria can occur in three ways: transformation, transduction, and conjugation. According to the given information, marine Bacteroidetes have enzymes required to digest porphyran and agarose. <em>B. plebeius</em> might have acquired the genes for these enzymes from marine Bacteroidetes by horizontal gene transfer. This resulted in its ability to digest the marine seaweed while its close relative species cannot do so.

Nuclear fusion is the combining of atomic nuclei to produce energy and new types of
galben [10]
Im not sure how to answer this since there were no choices given but I will answer by telling you what nuclear fusion is...

so basically nuclear fusion is the merging or combining of 2 isotopes, typically isotopes of hydrogen, under conditions of extreme temperature and pressure thus resulting in the release of massive amounts of energy. I think the answer to your question would be new types of electricity because the heat emitted from the reaction could be turned into electricity by using its steam. This is what happens in nuclear reactors  

i hop this answers your question
