Classify these four newly discovered organisms by selecting the domain to which they belong. A marine biologist took a sample from a hot spring. The cell has no nucleus and looks different from bacteria found in water.

A seed was discovered and, when planted, grew to be a large flowering plant.

This organism is a single cell that was isolated from the human body, has no nucleus, and was causing the patient to be ill.

A new type of worm was discovered in some bananas on a cargo ship.

real, smaller and upside-down.   so the answer should be b.

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
