The correct answer is C. Translation.
The given figure is the scheme of the gene expression. It provides the flow of genetic information from a DNA sequence to a protein synthesis inside cells. This process of flow of genetic information from DNA to RNA is called transcription and the process of flow of genetic information from RNA to protein is called translation.
Thus in given figure label A is to be replaced by transcription and label B is to replace by translation.

"An oxygen-rich environment would cause a mass extinction of prokaryotes." Supports current scientific theories of how life might have originated on Earth.
<u>Explanation:
</u>
The reacting power of oxygen increases rigorously in an oxygen- rich environment, which leads to huge fire ignition even with the slightest spark which is generally non hazardous at all. Many prokaryotic organisms do not need oxygen as they perform anaerobic respiration. Oxygen is dangerous for some prokaryotes.
There were some prokaryotic organisms who were giving out oxygen as waste. Such excess amount of oxygen was hazardous for the environment and hence mass extinction was required to keep a check on the excess amount of oxygen being released.
Answer: The estimated size of the population is 150
Explanation: For the Mark-Recapture method, there is a formula that can be used:
N = (M × C)/R
where :
N = estimated number of individuals in the population
M = number of individuals captured and arked
C = total number captured the second time (with and without a mark)
R= number of individuals ecaptured (those with a mark)
So with this formula we can calculate an estimation of the population of rodents. Because there is no number of rodents captured the second time given, we will assume 30 was caught again, making the 20% found marked being 6. We calculate it as:
N = (M × C)/R
:N = ( 30 × 30)/ 6
:N = 900/6
:N = 150 estimated rodents in the population
