Answer:
Producers are limited by consumers.
Explanation:
Answer:
Cell size is limited by a cell's surface area to volume ratio. A smaller cell is more effective and transporting materials, including waste products, than a larger cell. Cells come in many different shapes. A cell's function is determined, in part, by its shape.

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.
This is going to be false. There were mammals that had some characteristics of dinosaurs, such as sharp teeth.
The right answer is A.
Storing and transmitting the genetic information is the role of the DNA.
Proteins are biological macromolecules found in all living cells. They are formed of one or more polypeptide chains. Each of these chains consists of the sequence of amino acid residues linked together by peptide bonds. They can have multiple roles depending on their structure and composition
1- Maintenance of oncotic pressure
2- Buffer role
3- Transport function
4- Enzymes and Coenzymes
5- Role in coagulation and fibrinolysis
6- Role in immunity and allergy
7- Role in inflammation
8- Hormonal role
