Answer:
See the answer below
Explanation:
<em>Amphibians are not totally adapted to live on land because the aquatic environment is needed for several life processes such as </em><em>reproduction</em><em>, </em><em>respiration</em><em>, and sometimes, </em><em>feeding</em><em>.</em>
<u>The eggs of amphibians are without any protective shells and will suffer desiccation in the terrestrial environment. Hence, water is needed in order to protect the eggs. In addition, the male am</u>phibians shed their sperm in the water close to the female eggs.
<u>The young ones of amphibians are essentially aquatic and may not survive out of water for a long time because they only breathe gills</u> - the lung is yet to develop or poorly developed at this stage. They have to grow and develop to a certain stage in water before they can start surviving on land.
Answer: dehydration synthesis reactions and hydrolysis.
Explanation:
<em>Large biological molecules often assemble via dehydration synthesis reactions, in which one monomer forms a covalent bond to another monomer, releasing a water molecule in the process. </em>
<em />
<em>The process of splitting the bond between monomers is called hydrolysis. Since a water molecule was lost during dehydration synthesis, hydrolysis brings the water back.</em>
