In an experiment, a scientist compares the effect of adding acid rain to
samples taken from two different lakes. the scientist observes that ten drops
of acid rain added to water taken from lake minnetonka in southern
minnesota does not change the ph from 7.5, but ten drops of acid rain added
to water taken from upper kintla lake in glacier national park causes the ph
to change from 7.5 to 5.2.
which conclusion is supported by these observations?
o
a. both lake minnetonka and upper kintla lake contain a buffer,
o
b. upper kintla lake contains a buffer, but lake minnetonka does
not
o
c. neither lake minnetonka nor upper kintla lake contains a buffer
o
d. lake minnetonka contains a buffer, but upper kintla lake does
not

both anaerobic and aerobic respiration use glucose (or other carbohydrates), proteins and lipids to produce atp and nadh. cell uses those energy molecules, obtained from food and   breaks them down during the chemical reactions of respiration. in anaerobic respiration, nadh is regenerated to nad+ by enzymes lactate dehydrogenase (lactate is produced, e.g. in muscle cells) or by alcohol dehydrogenase where ethanol is produced (alcohol fermentation), while in aerobic respiration, electrons from nadh are deposited in the mitochondria to regenerate nad+ (electron transport chain. anaerobic respiration produces 2 atp per molecule of glucose compared to aerobic respiration where about 38 atp molecules are produced.

because the light is a great source of energy for the plants to survive. (i hope this )

the cost of mining is extremely low compared to the money earned from mining, creating income to improve the environment.
