Suppose a persons stomach wall was irritated by an over-secretion of stomach acid. why do you think a person would take milk of magnesia, a basic solution? explain your answer in terms of ph.

The pH of stomach secretion is low. This means it is acidic. Too much production can corrode the stomach wall. Therefore in such a situation drinking a basic solution with a higher pH neutralizes some of the stomach acidic secretions hence relieving the effect;

Acid + Base - Salt + Water  

the speed increase from w to x due to increased gravity force

the speed decreases from x to y due to decrease in gravity

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
