Which statement is true?
a) hydrolysis of atp to adp and phosphate releases about 14 kj/mol of free energy.
b) ctp hydrolysis can be a source of chemical energy.
c) datp is the most common source of chemical energy in cells.
d) hydrolysis of the α, β and β, γ phosphoester bonds of a nucleotide is used as a source of chemical energy.

b: CTP hydrolysis can be a source of chemical energy

Explanation:

Purine and pyrimidine nucleotides are important sources of energy that drives reactions in biological systems. These nucleotides include;

Hydrolysis of ATP to ADP yields about 57 kJ/mol of energy, dATP acts as a substrate for DNA polymerase during replication and can also act as energy transferring molecules but definitely not the most common source of chemical energy in the cell. Hydrolysis of phosphodiester bonds of a nucleotide is significant in DNA repairs and not used as a source of chemical energy.

Hence, the correct option is b.

b because they naturally adapt to their environment plz mark brainliest

explanation:

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
