Astar is an example of a blackbody radiator because (1 point)
it reflects most of the light falling on them
it can neither emit nor absorb all wavelengths of light
it’s spectrum shifts to short wavelengths as temperature increases
it’s wavelength peaks in the blue end of the spectrum as temperature decreases

The correct answer is -  Base pairing rule and DNA.

Explanation:

According to the base pair rule during transcription, along with antisense strand DNA, the RNA was made and the bases of the purines and pyrimidines strands bind together, Uracil paired with the A-strand and the C strand being paired to G-strand in transcription within the nucleus.

Thus, the correct answer in the first line is "Base-pairing rule" while in the second line is "DNA".
