Answer:
Transcription.
Explanation:
Transcription may be defined as the process of formation of RNA molecules from the DNA template. Specific enzymes and chemical factors are required for the process of transcription.
During transcription, the RNA copy is made from the DNA template. Three main different types of RNA are messenger RNA, transfer RNA and ribosomal RNA.
Thus, the answer is transcription.
The answer is b, decrease the oxygen gas pressure
Take note that the total distance that needs to be traveled is 360 miles. The train is moving at 60mph and 2.5 hours have passed. To get the remaining distance, first you need to solve for the distance traveled already.
Distance is equal to the velocity times the time travelling or:

So considering the given we can get the distance traveled in 2.5 hours.



So far, Ainsley traveled 150 miles. If her town is 360 miles away, you can get the remaining by subtracting the distance already traveled from the total distance.
360 miles - 150 miles = 210 miles.
Now if you want to put that into a single equation you can do that by combining all the equations together.
d = 360 miles - (vt).d = 360 miles - (60mph)(2.5 h)
d = 360 miles - 150 miles
d = 210 miles
