The given question lacks the choices that are essential to answer, however, the concerned part is as follow:

Nuclear fission is used to produce electricity at nuclear power plants. Nuclear fission involves one large atom splitting into two smaller atoms. Nuclear fission takes place in the nucleus of an atom. Nuclear fission releases a huge amount of energy

Nuclear fission is different than nuclear fusion are -

Nuclear fission is used to produce electricity at nuclear power plants. Nuclear fission involves one large atom splitting into two smaller atoms.

Nuclear reactions are of two types; nuclear fusion and nuclear fission:

These processes occur in the nucleus of an atom.In nuclear fission a heavy and unstable nuclear splits into two parts to produce very high energy.in nuclear fusion, two small and unstable nuclei fuse and produce a very high amount of energy higher than nuclear fusionNuclear fission is used in producing electricity at nuclear plants.

Thus, Nuclear fission is different than nuclear fusion are -

Nuclear fission is used to produce electricity at nuclear power plants. Nuclear fission involves one large atom splitting into two smaller atoms.

Nuclear fission is the splitting of atoms while fusion is the combining

Explanation:

fission does not occur naturally while fusion occers in stars

transcription is a process in which information is rewritten. it is something our cells must do, in a more specialized and narrowly defined way. in biology, transcription is the process of copying out the dna sequence of a gene in the similar alphabet of rna. it needs to happen in the nucleus because that's where the dna is. dna is always inside the nucleus unless the cell is dividing.

transcription is the first step in gene expression, which involves copying a gene's dna sequence to make an rna molecule. transcription is performed by rna polymerases. it has three stages: initiation, elongation, and termination. rna molecules must be processed after transcription in eukaryotes.

explanation:

long version:

the protein synthesis consists two processes which are, transcription and translation. transcription takes place in the nucleus. it uses dna as a template to make an rna molecule. rna then leaves the nucleus and goes to a ribosome in the cytoplasm, where translation occurs. transcription is the first part of the central dogma of molecular biology: dna → rna. it is the transfer of genetic instructions in dna to messenger rna (mrna). during transcription, a strand of mrna is made that is complementary to a strand of dna.

these three stages are:

initiation: in which is the beginning of transcription.occuring when the enzyme rna polymerase binds to a region of a gene called the promoter. this signals the dna to unwind so the enzyme can ‘‘read’’ the bases in one of the dna strands. the enzyme is now ready to make a strand of mrna with a complementary sequence of bases.

elongation: in which is the addition of nucleotides to the mrna strand. rna polymerase reads the unwound dna strand and builds the mrna molecule, using complementary base pairs. there is a brief time during this process when the newly formed rna is bound to the unwound dna. during this process, an adenine (a) in the dna binds to an uracil (u) in the rna.

termination: in which is the ending of transcription, and occurs when rna polymerase crosses a stop (termination) sequence in the gene. the mrna strand is complete, and it detaches from dna.

there are mainly three domains in biological classification namely; archaea, bacteria, and eukarya.

archaea includes all the prokaryotic cells which are characterized by their lipid membranes. they have branched hydrocarbon which is attached to glycerol through an ether linkage.

bacteria includes all the prokaryotic cells, the cell membrane of which are made up of the unbranched fatty acid chain. in addition, they are attached to glycerol through an ester bond.

eukarya includes all the eukaryotic cells, that is, the cells contain a nucleus and other membrane-bound cell organelles.

they can be autotrophic as well as heterotrophic, unicellular as well as multicellular

they include kingdoms like protista, plantae, animalia, fungi et cetera.
