Salt in the ocean comes from rocks on land. The rain that falls on the land contains some dissolved carbon dioxide from the surrounding air. This causes the rainwater to be slightly acidic due to carbonic acid (which forms from carbon dioxide and water).
The another are differentiated from the anamniotes by the presence of their terrestrially adapted eggs. These eggs are protected by amniotic membranes. Development of these membranes have provided another with their own aquatic environment needed for development.
The development of amniotic membrane is a characteric of amniotic eggs. These membranes include: chorion' facilitating the exchange of gases between the embryo and the mother; amnion, protection the embryo from injuries and shock and also aiding hydration; allantois, excretion of nitrogenous waste such as urea and uric acid etc and also help in respiration.
Another characteristics is waterproof skin due to the presence of lipids.
Another is the existence of costal rib ventilation of the lungs: enables of loss of CO2 through the lungs rather than buccal pumping as foumd in anamniotes.

Memory consolidation
Explanation:
Short term memory is stored in the brain for relatively short period of time especially for few minutes. Long term memory is stored in brain for long period ( years or lifetime).
Short term memory can be converted into the long term memory by association, rehearsal and involved with emotional state. Memory consolidation is the process of learning new things and store them in previously stored memories. Hence, memory consolidation does not increase the conversion of short memory to long term memory.
