Carbon is released into the atmosphere only during the burning of fossil fuels
Explanation:
During the process of fuel burning, carbon is released in the atmosphere. The human invented power plants, factories, cars and other vehicles releases carbon in the form of carbon di-oxide in atmosphere.
However, the cellular respiration is similar to that of fuel burning as it is too a combustion process. But the carbon produced in this process fuels the inner cellular activities rather than releasing it in the atmosphere.
<span>Tertiary</span> structure - three-dimentional structure of one polypetide chain.
Proteins are considered as for their conformation in four different stages:
Primary structure is referred solely to the sequence of amino acids<span> in the polypeptide chain.
</span>Secondary structure is the immediate basic folding of a protein and it can be α-helix and β-sheets.
Tertiary structure is the three-dimentional folding of a singles polypetide.
Quaternary structure is the thee-dimenional structure that results from the combination of two or more individual polypetides working as single protein.
I think the answer is A im sorry if its not right
