Which of the following statements best defines the term operon?
a. an operon is a region of rna that consists of the coding regions of more than one gene.
b. an operon is a region of dna that codes for sugar-metabolizing enzymes.
c. an operon is a region of dna that codes for a series of functionally related genes under the control of the same promoter.
d. an operon is a region of dna that consists of a single gene regulated by more than one promoter.

C

An operon is a function portion of a DNA strand that contains a cluster or genes that are controlled under one promoter. This is found in an bacteria or cell and controls protein synthesis. It helps conserve the energy of the cell by only producing proteins when necessary.

i think its control and coordinate because im pretty sure thats what tissue does and the joints are what control movement and then your skeletal/ bones provides portection. hope that .

answer: zinc is the substance which has a volume of 1.38 .

density is defined as the mass of an object per unit volume.

it can be calculated by dividing mass of a substance by its volume i.e.

si unit of density is kg per cubic meter and cgs unit of the same is gram per cubic centimeter.

now from the given data volume can be calculated by the formula .

hence, the volume of aluminium will be = which comes out to be 1.703 .

similarly, volume of zinc, chromium, and nickel will be 1.378 , 0.869 , and 0.356 respectively.
