the answer is cell cycle!
Answer:
minerals may then be deposited, for example, as stalagmites or stalactites
The water dissolves and carries away the solid rock gradually enlarging the cracks, eventually forming a cave. Ground water carries the dissolved minerals in solution.
Explanation:
Ground water is a strong erosional force, as it works to dissolve away solid rock. Carbonic acid is especially good at dissolving the rock limestone. Working slowly over many years, ground water travels along small cracks.
Solution:
A peptide bond is a chemical bond formed between two molecules when the carboxyl group of one molecule reacts with the amino group of the other molecule, releasing a molecule of water (H2O). This is a dehydration synthesis reaction (also known as a condensation reaction), and usually occurs between amino acids.
Thus the required right answer is carboxyl group and other molecule.
