Measurements of the amount of dna per nucleus were taken on a large number of cells from a growing fungus. the measured dna levels ranged from 3 to 6 picograms per nucleus. in which stage of the cell cycle did the nucleus contain 6 picograms of dna?

It's on the G2 stage

Explanation:

During the cell cycle, DNA levels range from a minimum during G1 to a maximum after S phase but before cytokinesis. Since the cell in question has more than the minimum but equally to the maximum per nucleus, it must be in the final phase, which is G2.

their crystal patterns have been disrupted by stress

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
