Trichodesmium is a nitrogen-fixing cyanobacteria. Why might this cyanobacteria be important to other organisms in nitrogen-poor
eimsori [14]
Cyanobacteria don't need oxygen to survive they produce oxygen. They where the first ever known organisms on the planet and they produced oxygen in the oceans which was absorbed by iron deposits and then once the iron had oxygen the ocean got the oxygen until it got into the atmosphere and Eukaryota bacteria evolved. So the answer would be: <span>They convert nitrates from the water into nitrogen gas (N2) that is released into the atmosphere.</span>

antiseptic1488 [7]

Answer:

Humans are gradually altering the climate and the earth's temperature through burning fossil fuels, destroying forests, and rearing animals.

Explanation:

This significantly increases the amount of greenhouse gases already present in the atmosphere, increasing the greenhouse effect and contributing to global warming.

Climate change is mostly caused by the greenhouse effect. Some gases in the Earth's atmosphere act as greenhouse glass, trapping heat from the sun and preventing it from escaping into space, causing global warming.

Which of the following statements describes a central role that ATP plays in cellular metabolism?
DaniilM [7]

Answer: The correct answer is D. ATP provides energy coupling between exergonic and endergonic reactions.

ATP hydrolysis is an exergonic reaction, as a large amount of energy is released when this molecule is hydrolyzed. ATP is converted into ADP ( adenosine diphosphate)  and inorganic phosphate. The energy released in this reaction is utilized by the endergonic reactions ( which require energy) such as photosynthesis.

Thus, the central role that ATP in cellular metabolism is that it provides energy coupling between exergonic and endergonic reactions.
