A prominence refers to a bright, large, gaseous feature projecting externally from the surface of the Sun, usually in a loop shape. Prominences are attached with the surface of the Sun in the photosphere and elongate outwards into the corona of the Sun.
The prominences are related to the discharge of the high energy constituents called a solar flare. These solar flares have been considered to influence electronic communication as their energy blends up the upper atmosphere of the Earth, making the radio transmissions weak and noisy.
Hence, the correct statements are prominences can disturb radio communications on Earth and prominences are loop-shaped.
During interphase, the cell grows and the DNA replicates. After that there's the mitotic phase where the replicated DNA and the contents in the cytoplasm are sperated in a way that the cell divides.
