There are several, including decomposing animal matter, and various minerals and salts.
A weak acid
Water acts as a natural solvent to dissolve the water
Water is not a good pH buffer.
The chemical formula for water is H2O. In the human body it acts as a temperature stabilizer, it is a reactant in several types of synthesis and decomposition reactions, it serves as a protective buffer as in the cerebral spinal fluid, and lastly it acts as a solvent.
Buffer
The buffer AP1 is vital in DNA extraction as it acts as a cleanser to break up the lipids surrounding the cellular membrane. The buffer also maintains the right environment for the DNA so it is not damaged during the extraction process.
Decaying Plant Matter: APEX
A.
c. Decomposing animal matter
Literally every answer was wrong so the answer on apex (as all the other answers werent even an option for me) is decaying plant matter
Decaying plant matter
chalk, calcium
bicarbonate buffer is instant, followed by respiratory, renal, and phosphate.
There are many seashores that have a moderate temperature. This is because the water acts as a buffer and stabilizes temperature.
