On early earth, the one that was referred to as "Primordial Soup" is : B. The combination of organic compounds in warm salty water
Many speculated that these organic compounds mutated and evolved into a single cell organism, which became the origin of the organisms on earth
hope this helps
The biologists have categorized protozoans as a part of Kingdom Protista, they have attempted to sort protists in comparison to three of the other kingdoms, that is, animals, plants, and fungi. However, this has not worked as several of the protists demonstrate features from two or more of these kingdoms.
The protozoans show considerable diversity, that is, some live as predators, some as parasites, and some others are thriving as producers. Scientists have attempted to categorize the organisms within the protists as either fungus-like, plant-like, or animal-like.
However, close testing and genetic examination have shown that these classifications often does not imply.
Answer;
Amino acid side chains have many carboxyl and amino groups.
Explanation;
-A buffer solution is a solution that resists changes in pH when small quantities of an acid or an alkali are added to it. It is a chemical substance that helps maintain a relatively constant pH in a solution, even in the face of addition of acids or bases.
-Buffering is important in living systems as a means of maintaining a fairly constant internal environment, also known as homeostasis.Small molecules such as bicarbonate and phosphate provide buffering capacity as do other substances, such as hemoglobin and other proteins.
-
Protein buffer systems depend upon proteins, as opposed to nonprotein molecules, to act as buffers and consume small amounts of acid or base. Since amino acids have the capability of reacting with both acid and base, they naturally act as buffers.
Amino acids they are called. #YODARULES
