What happens when muscle cell don't have enough oxygen? a.)decrease carbohydrate production b.) increase protein synthesis c.)decrease ph d.)decrease size

It begins producing acids and converting glucose instead of energy and the anaerobic exercise takes over then the power output drops and fatigue is getting in

When muscle cells does not he enough oxygen the carbon dioxide concentration increase as compared to the oxygen concentration. The increased concentration of carbon dioxide will cause acidic condition hence the pH decreases. Hence the correct answer is option C decrease in pH.

An ecosystem is in a certain area and includes living and non living plus there is weather conditions and a biome is a large amount of area with similar climate.so ecosystem is based on weather and biome is based on the average climate
