The correct answer is - cyanobacteria.
The atmospheric oxygen came from the cyanobacteria. These were one of the earliest living organisms on Earth. The cyanobacteria was using photosynthesis in order to create its own food. The photosynthesis process requires sunlight, carbon dioxide, water, and oxygen. The oxygen is mostly released as a waste product from the process of photosynthesis, thus the cyanobacteria were literally releasing oxygen that was ending up into the atmosphere. As more and more cyanobacteria there were across the planet, more and more oxygen they were releasing into the atmosphere, slowly changing the composition of the atmosphere, and setting the basis of it as we know it now.
35.5 degrees.
Explanation:
ACB = 1/5 of AOB
Plug in 61 degrees for AOB.
1/2 of 61 = 35.5.
If not correct, then you may correct me.
I believe the answer is E. d41 because it goes a11, A12, b21, B22, c31, C32, then it goes lowercase d41 and then the next one is going to upper case D42.
Hope this helps.
Answer:
The cold front is to the west of Dallas.
Explanation:
The curved line with triangles on the map represents a cold front, and the direction of the front is indicated by the way the triangles are pointing.
The cold front is most likely to affect Dallas in the coming hours and will probably bring rain, wind, and possibly thunderstorms to the Dallas area. After the passage of the cold front, the pressure will rise and the temperature will drop. The wind will now be out of the northwest.
The predictions are no always exact because some winter cold fronts can bring snow and not all cold fronts generate thunderstorms.
The reason for language diversion is the isolation of the people who speak the same language, but due to diversion and lesser contact between these people, now the language is used only in the dialects.
