A constitutive gene is unregulated, which means that its expression level is relatively constant. The expression of a regulated gene varies under different conditions. In bacteria, the regulation of genes oftentimes occurs at the level of transcription by combinations of regulatory proteins and small effector molecules. In addition, gene expression can be regulated at the level of translation or the function of a protein can be regulated after translation is completed.

An inducible gene is a gene whose expression is either responsive to environmental change or dependent on the position in the cell cycle.The rapid activation of gene expression in response to stimuli occurs largely through the regulation of RNA polymerase II-dependent transcription

kozerog [31]

Answer:

clusters of round shape bacteria

Explanation:

Microscopic examination of the potato salad should reveal clusters of round shape bacterium.

Staphylococcus or Staphylococcal are those that are round in shape (from the word 'coccus') and occur in clusters as opposed to individually or in chains. The word is derived from two Greek words - staphyle which means bunch of grapes and kokkos which means to be round.

Hence, when a magnified image of the Staphylococcus aureus is produced by the microscope, clusters of round shape bacteria would be seen.

The purpose of cell division

posledela

Cell devision has three main purposes; repairing the organism, reproduction and growth. Repairing the organism is important because it will allow the organism to survive longer. Reproduction is important because it allows the species of organism to live and survive longer. Growth is important because it allows the organism to grow larger and stronger.

You could also say that the neutron is the odd man out because the number of protons and electrons are the same because the negative charge from the electronics attracted to the positive charge from the proton.

On the next line you could say the election is the odd man out because the protons and neutrons reside in the nucleus and the electrons fly at high speeds in the electron cloud.
