Answer:
RNA
Explanation:
Transcription is the second stage of central dogma of life (1. replication, 2. <u>transcription</u>, 3. translation). 
During transcription, DNA (which is already replicated) is transcribed to RNA. This is because, the genetic information is present within nucleus and thus it is required to be transported outside the nucleus in order to  perform key enzymatic functions. Therefore, transcription takes place and the genetic information travels outside in the form of RNA, where  ribosomes decode this message to form proteins. The ribosomes make proteins (translation) required for enzymatic functions.

Answer:
B. 1,000,000
Explanation:
A pH of 14 is 1 x 10^-14 while a pH of 8 is 1 x 10^-8. 
So, all we have to do is subtract 8 from 14 and then solve it.
14 - 8 = 6 
1 x 10^6 = 1,000,000
