Answer:
b, a, d, c, e
Explanation:
The lac operon is called lactose operon is a cluster of genes with a promoter. The bacteria uses lactose as the source of energy by the proteins coded by genes. This is present in prokaryotes.
The regulatory gene codes for repressor protein. The repressor binds to lactose and prevent its binding to operator. In the absence of lactose repressor gets activated and binds with operator. Thus, RNA polymerase is prevented from binding the promotor. The transcription of genes inhibited. Thus correct order is b, a, d, c, e.
Chain reaction
Nuclear energy
Explanation:
Question 1:
Chain reaction:
A reaction in which when one occurs, it starts a series of other fission reaction is called a chain reaction.
Most nuclear reactions are chain reactions in which does not come to rest in one step like chemical reaction.
In nuclear reactions like which fusion and fission, one step leads to another until an atom attains stability or a stable product is formed.
The energy needed to sustain the chain process is produced in the previous reaction.
Nuclear energy:
The type of energy used in a nuclear power plant is called a nuclear energy. Nuclear energy is used to generate power in nuclear plant.
During a nuclear decay process, a huge amount of energy is released. This energy is channeled into electricity production and to do other useful works.
Nuclear energy is classified as a non-renewable source of energy.
