A substance with a pH of 6 is categorized as an acid. While it's close to neutral (pH 7), anything less than 7 is considered an acid in the field of chemistry.
In the context of chemistry, the substance you're referring to, with a pH of 6, is considered an acid. The pH scale runs from 0 to 14; substances with a pH less than 7 are classified as acids, substances with a pH greater than 7 are termed as bases, and a pH of 7 is neutral, represented typically by pure water. Even though a pH of 6 is close to neutral, since it's less than 7, it still falls under the category of an acid.

Answer: Cyanobacteria also known as blue green algae , they make their food by the process of photosynthesis.
Explanation: features of Cyanobacteria :-
Photosynthesis in Cyanobacteria is because of the presence of two pigments green pigment chlorophyll and blue pigment phycobilins. They found in aquatic and terrestrial habitat. They are adapted to live in extreem conditions.
They do not have membrane bound nucleus and other organells.
Answer:
Earth has many layers because of its complex history and the processes that have shaped it over billions of years.
