Answer: The correct answer is-
C.They replaced carbon dioxide with oxygen in the atmosphere.
Cyanobacteria ( also known as blue green algae) is a large phylum of bacteria that is capable of synthesizing its own food using carbon dioxide and water in the presence of sunlight ( photosynthesis).
They contain a green pigment called chlorophyll that absorbs energy from sunlight and helps in the formation of food ( glucose). They release oxygen as a byproduct in the atmosphere.
As these organisms utilize carbon dioxide ( that is present in the atmosphere) to give oxygen in return, therefore, they affected early atmosphere of Earth by replacing carbon dioxide with oxygen.
Thus, option C) is the right answer.
Nocardia is important in bioremediation process because they can decompose polycyclic aromatic hydrocarbons, polychlorinated biphenyls, chlorophenols, sulfonated azo dyes and alkanes.
<h3>What is bioremediation?</h3>
Bioremediation is the process of using living organisms such as microorganisms to degrade wastes in the environment in order to return it to its previous healthy state.
An example of a microorganism used in bioremediation is Nocardia spp.
Nocardia is important in bioremediation because they can decompose polycyclic aromatic hydrocarbons, polychlorinated biphenyls, chlorophenols, sulfonated azo dyes and alkanes.
Based on the complete question which is given as follows:
"Nocardia are of particular interest to scientists for the process of bioremediation because they can degrade _________. (Check all that apply) A. petroleum Hydrocarbons B. rence benzone C. pectin Keratin D. Decode Chiron", the correct options are A and B.

The two types of waste in the cellular respiration are aerobic respiration and anaerobic respiration.
Answer: Thermal energy from the fire moves to the water in the form of heat.
Because according to second law of thermodynamic, heat flows from higher to lower temperature region. Heat is the transfer of energy from an object at higher temperature to an object at a lower temperature. so energy flows from warmer to colder objects
