Before a cell goes through cell division (mitosis), it must grow and make a copy of its DNA which is termed as an Inter-phase.
<u>Explanation:</u>
Some tasks must be carried out by the cells before they undergo division: The cell must grow, it must copy the genetic material (DNA) present in it, and divide into two daughter cells. These steps carried out by cells are termed as cell cycle.
Cells that contains a nucleus or Eukaryota cells, there are two major phases called interphase and the mitotic (M) phase. that comprises the cell cycle.
In inter-phase, growth of the cell and making a copy of its DNA is carried out.
In mitotic (M) phase, the cell separation of the DNA in the cell into two sets and division of its cytoplasm takes place resulting in the formation of two new cells.
Answer:
You could check the pH!
Explanation:
This is an idea, when you break down H2O2 (Hydrogen peroxide) you will be left with H2O (Water) and O2 (Oxygen gas). H2O2 theoretically would have a lower pH than water. Water has an average pH of around 7 while H2O2 will have a pH of about 4.5.
So theoretically to figure out if hydrogen peroxide is being broken down you can test for the pH. This is a very simply process, you just stick a little peice of litmus paper into the solution and immediatly it will change color to tell you the pH.

Answer:
Operons afford the organism the opportunity to simultaneously regulate transcription of multiple genes, whose products are active in the same process.
Explanation:
Operon is the group of related genes and the operator and promoter sequences that regulate their expression. All the genes in an operon are expressed together and are under the regulation of the same promoter and operator sequences.
Operons consist of the genes that are involved in related metabolic pathways. For example, the genes that code for the enzymes of lactose catabolism are expressed together as lac operon. It allows simultaneous expression of the genes of lactose catabolism only when lactose is present in the medium. Similarly, these genes are inhibited simultaneously in absence of lactose by binding of repressor protein to the operator sequence.
