One adaptation to life in flowing water is - breeding in oceans
Adaptation is not a quick process but rather it is a slow and time taking process. It can be defined as an evolutionary process where an organism becomes increasingly well suited to living in a particular habitat. It is a feature of an organism that enables it to live in a particular habitat.
The parotid duct empties into the vestibule at the level of the second upper molar. Parotid vestibular submaxillary sublingual submandibula.
- The upper second molar tooth's crown is direct across from the opening of the parotid duct, also known as Stensen's duct, which secretes serous saliva and enters the gingiva-buccal vestibule of the mouth.
- The parotid ducts typically exit near the maxillary second molars, and they can be felt as little bumps (papillae) on both sides of the mouth. At the sublingual caruncle, the Wharton duct, the primary excretory duct of the submandibular gland, empties into the oral cavity. The sublingual caruncle is a papilla that is situated lateral to the frenulum linguae and medial to the sublingual gland. A set of lymph nodes located in front of the ear is known as the superficial parotid lymph nodes.

Answer:
Chemogeny may be a theory of chemical evolution that depends on the chemical reactions and formation of drugs on the bases of chemical reactions. This theory says that “Life occurs as a results of evolution of inorganic matter”.
In the 1920's Scientists Oparin and Haldane, developed this hypothesis of the chemical origin of life from the primitive atmosphere of the world having matter like methane, ammonia and water. there have been very low concentrations of oxygen thanks to the presence of high temperatures like 5000-60000C. So, these conditions weren't suitable for the free existence of organic compounds, so reactions started happening .
Under conditions like high sunlight and warmth , inorganic matter gets converted to inorganic compounds. And this might end in the storage of organic compounds, which gets more and more concentrated with the passage of many years.
These compounds interact with one another and end in “life”.
So, chemogeny is that the process of chemical evolution of earth and formation of life from pre-existing matter with the assistance of chemical reactions.

Hopefully I was able to help you with the concept. Good luck!
