Before the presence of living organisms earth was a very different place match each fact about about precambrian earth to the sphere most affected

The correct matches are:

- Atmosphere - Oxygen spilled into this sphere from ocean waters;

The majority of the oxygen in thee Precambrian Earth was not in the atmosphere, but instead it was in the ocean waters. With the emergence of life, large portions of this oxygen went into the atmosphere as it was released as a waste product.

- Biosphere - Cyanobacteria started to emerge as a life form;

The cyanobacteria were one of the earliest life forms. They were producers, and started to use the process of photosynthesis in order to produce food. The usage of this process caused lot of changes on the Earth later on.

- Hydrosphere - Oceans contained far less salt than they do today;

The rocks and minerals in the Precambrian Earth were not weathering and eroding in the manner they are now. Instead they were kept compact for much longer periods, influencing the mixture of of different components with the water as well in meantime.

- Lithosphere - Oxidation in rocks and minerals was not possible;

Because there was way to small amount of oxygen in the atmosphere, very close to 0%, the oxidation of rocks and minerals was not possible, as the oxygen is the gas that causes this process.

what is the aerea shown

explanation:

hey bro i looked it up on google the structure of the eye-spot in euglena viridie, e. ehrenbergii, and phacus pyriyorme is not as franzé haa described it. the so-called “crystal body” and “lens bodies” were not found in any of the individuals of the species examined by me. as earlier observers have stated, the eye-spot consists simply of a mass of pigment granules arranged in a single layer, and probably embedded in a protoplasmic framework, but the latter could not be seen, and its presence was only inferred from the fact that the pigment granules must be held together in some way, thd the eye-spot as a whole is capable of expansion, and that the pigment granules can be separated from each other.

hope this   and an i get brainlsiest
