The ph scale measures whether solutions are acidic, basic, or neutral. the ph needed by living cells is very specific, and can vary only slightly. because all living things are made up of cells that are mostly water, the ph of cells is close to?

The pH of cell is close to the pH of water

Explanation:

Water is chemically neutral which means it is neither acidic nor basic in nature. Since acidic substance have pH less than 7.0 and basic substance have pH more than 7.0, water being neutral has exact pH of 7.0. Therefore, all cells which predominantly consists of water will have their pH value near to the pH value of water but it is not sure whether it will be slightly less or slightly more than 7.0

regulation of gene expression. gene expression can be regulated by various cellular processes with the aim to control the amount and nature of the expressed genes. these regulatory proteins bind to dna and send signals that indirectly control the rate of gene expression
