The correct answer is A. maintaining homeostasis.
Homeostasis is a term referring to an organisms continuous process of maintaining and auto-regulating the conditions of its internal environment. Variables such as pH, temperature, and fluid balance need to be at optimal conditions in order for the organism to function properly.
In this example, the phosphate buffer system permits the organisms to maintain a constant pH in their intracellular fluid. This is one of the organism's homeostatic mechanisms.
Most likely a silent mutation. Silent mutations are mutations in DNA that do not have an observable effect on the organism's phenotype because the same amino acid is produced regardless of the change in the nucleotide sequence by the mutation.
Answer:
The O2 gas in uses in Aerobic Respiration and That O2 is performing that process to make ATP for your body and making glucose to function your body
Explanation:
Lactic Acid Fermentation is Anaerobic Respiration which doesn't Involve Oxygen
Sorry if I'm wrong
Hope this helps!
Airborne is the most common.
