The statement "The DNA strand is used as a template for which a complementary RNA strand can be produced" accurately describes a step within transcription (option C)
Transcription is the process of copying genetic information from DNA into RNA. The DNA strand is used as a template, and the RNA polymerase enzyme reads the DNA strand and adds complementary nucleotides to form a new RNA strand.
The RNA strand is then released from the DNA and can be used to make proteins.

Loudness of a sound relates the intensity of any given sound to the intensity at the edge of hearing.
The loudness of sound waves that are in phase will be twice as loud as they would be by themselves, if they are out of phase, a beat will be produced, or maybe a neighborhood of no sound at all.
The intensity of a sound is the power of the sound in Watts divided by the area the sound covers in square meters. The loudness of a sound relates the intensity of any given sound to the intensity at the edge of hearing.
Thus, the sound waves that are in phase will be twice as loud as they would be by themselves,if they are out of phase, the beat will be produced.
To know more about the loudness of sound waves follow the link:
B. 1 km/1000 m
C. 100 m/1 km
D. 1 km/100 m
