Answer:

Early cyanobacteria in stromatolites are thought to be responsible for increasing the amount of oxygen in the primeval Earth's atmosphere through their continuing photosynthesis. They were the first known organisms to photosynthesize and produce free oxygen.

How many kilometers above sea level would this mountain reach, and what would the approximate temperature be at this altitude?
UkoKoshka [18]

Answer:

It would be about 9 kilometers above sea level, and you can expect the temperature to be cold. (see explanation)

Explanation:

If there's no snow or rain and you’re not in a cloud, then the temperature decreases by about 5.4°F for every 1,000 feet up you go in elevation. That is 9.8°C per 1,000 meters. However, if you’re in a cloud, or it is snowing/raining, the temperature decreases by about 3.3°F for every 1,000 feet up you go in elevation. Thus meaning it’s a change of 6°C per 1,000 meters.

Changing one base in a gene could have the
saw5 [17]


answer: 2) sequence of building blocks of a protein found in a cell.

Just random FYI:

- it is a mutation, that is generally not looked upon as being severe or detrimental to the person

-by changing the base by either adding or deleting from a protein strand will cause the protein to be useless

-frameshift mutation deals with DNA sequence being shifted. For example: a DNA strand looks like a ladder. If one of the rungs on the ladders gets skipped and the next ladder rung gets the code that the previous rung should have gotten, then that is what a frameshift mutation is. Hopefully that makes sense. It's easier to explain if there was a picture.

there are other types of mutation but I won't get into them.


Hopefully this helped and good luck.
