Radiant energy

a. moves in waves

b. includes nuclear and chemical energy

c. needs a medium to travel through

d. is transferred through conduction

The correct answer is option A. "moves in waves".

Explanation:

Radiant energy is basically the energy that comes from the movement of electromagnetic waves. All hot objects produced infrared waves, and transfer part of their energy via radiant energy allowing that nearby and faraway objects gain heat energy. The transfer of radiant energy is known as radiation, this is the phenomenon that allows that Earth gets heat from the Sun.

we would need to see the picture to answer it

the dna molecules have a negative charge because of the phosphate groups in their sugar-phosphate backbone, so they start moving through the matrix of the gel towards the positive pole. power is turned on and dna fragments migrate through gel (towards the positive electrode).
