<u>Answer:</u>

Scientist think colonies of Cyanobacteria called stromatolites were responsible for the introduction of oxygen into earths atmosphere is true.

<u>Explanation:</u>

  • In primeval earth’s atmosphere, stromatolites (colonies of Cyanobacteria) are believed to have increased the level of oxygen by their photosynthesis process.
  • These are the first known organisms that started photosynthesis process and produced the oxygen to the earth’s atmosphere.
  • There is a theory that, these organisms produced oxygen in the environment and the organism disappeared that couldn’t live in the atmosphere with the oxygen.
  • Scientists gave this a name called as “great oxygenation event”.

The diagram below shows the relative concentration of molecules inside and outside of a cell. Which statement best describes the
11111nata11111 [884]

Answer:

4

Explanation:

This is the answer because I have tested it and got it correct. As oxygen-rich (and carbon dioxide-poor) blood travels by a cell the oxygen diffuses through the cell membrane to the area of lower concentration inside the cell. It can do this easily because the oxygen molecule (O2) is very small and has no charge or polarity. The oxygen is used up rapidly by mitochondria.

How would soil fertility likely change during the early years of primary succession?
11Alexandr11 [23.1K]
Primary succession is a method of fertilizing soil that was barren and had never supported plant life, for example soil left over by a moved glacier of lava.
The soil is first "normalized", using pioneer species such as lichens, algae and fungi.
After this, plants able to survive in less harsh conditions such as grasses.
Therefore, the fertility of soil during early years of primary succession does not increase much and it is a process that involves a long period of time.
