What end arrangement of atoms is present in amino acids that was also present in fatty acids?
Both amino acids and fatty acids have a carboxyl group at one end, which consists of a carbon atom double-bonded to an oxygen atom and single-bonded to a hydroxyl group (-COOH).
When did the Cambrian date start and end?
The Cambrian period began approximately 541 million years ago and ended around 485 million years ago. It is notable for the "Cambrian Explosion," a rapid diversification of life forms, particularly in marine environments. This period marks the first appearance of many major groups of animals in the fossil record.
What forms of living things characterized the Cambrian period?
Life took off in the Cambrian period (the Cambrian Explosion). By its end, all the main lines of animal types, whose descendants fill the world today, had been established. All of this diversity flourished in the sea; there was still no life on land. Fish w/out jaws were the first vertebrates. Just like molluscs & arthropods, early fish had a hard outer covering. This armor plating around their front ends was made of bone. They had probably ate by sucking in mud through their mouths.
What is the present participle of end?
Ending is the present participle of end.
What end arrangement is present in both amino acids and fatty acids?
Both amino acids and fatty acids contain a carboxyl group at one end of the molecule. This carboxyl group consists of a carbon atom double-bonded to an oxygen atom and single-bonded to a hydroxyl group (OH).
What event marked the end of the Precambrian Era?
The Precambrian Era ended with the beginning of the Cambrian Period, approximately 541 million years ago. This period is characterized by the sudden appearance of a diverse range of complex life forms in the fossil record, known as the "Cambrian explosion".
