Answer:
A. An OH group from one component and an H atom from the other form a water molecule.
C. Monomers or polymers are joined to form longer chains.
Explanation:
Dehydration reactions are the ones in which a water molecule is released during the formation of a covalent bond. Since these are "synthesis" reactions, complex molecules are formed from the simpler monomers. Therefore, dehydration synthesis refers to the reactions that form complex polymers by joining the monomers together.
For example, when a peptide bond is formed between two amino acids, OH group from one amino acid and "H" from the other amino acid join together and are released in the form of "H2O". A covalent bond is formed between the two amino acids. many amino acids are joined together in this way to form long polypeptide chains.
It can by a more truthful theory
Answer:
Over time, many species gradually adapted to a more oxygen-rich enviroment, allowing them to survive in shallow water and on land.
This would indicate that the most accurate diagnosis of your condition would be sickle cell disease.
Sickle cell disease is a condition that affects hemoglobin; the iron containing molecule in red blood cells that transport oxygen from the lungs to the rest of the body. This condition causes the red blood cells to become misshapen or deform into an abnormal crescent shape which can easily get accumulated together and block off small blood vessels. The blocking of the blood vessels will prevent blood from flowing to where it should in the body and this can result to pain and organ damage in affected persons.
