Co2 is the waste product of cellular respiration and fermentation. the yeast in this experiment are being grown in an oxygen poor environment and are thus performing alcohol fermentation. which of these statements correctly identifies the concentration in which yeast cells produce the most atp and why? a) 0% since no co2 was produced by the yeast cells. b) 10% since the co2 production is evidence of alcohol production. c) 50% since the co2 produced is evidence of atp production. d) 75% since it has the most glucose available for cellular respiration.

Option C

Explanation:

In fermentation, two ATP molecules are produced for every glucose molecule which is just half of the total number of ATP molecules produced during an aerobic cellular respiration process where four ATP molecules are produced per glucose molecule. This difference is due to the consumption of all NADH molecules in glycolysis due to which no NADH molecule enter electron transport chain reaction to produce ATP.

Hence, option C is correct

sand 60

clay 10

silt 30

sandy loam should be dominated by the sand. as the amount of sand increased, the amount of slit needed to anchor the plants' roots to the sand will also be increased. even though the amount is very little, 10% part of clay is still necessary for proper oxidation.

answer:

the water molecules are transferred from the roots to the stem or top parts of the tall tree because of important properties of water which are adhesion, cohesion and capillary action. cohesion is the property of water molecules keeps water molecules in a combined state by sharing of bonds between them at the atomic level. adhesion allows the interaction of water molecules with other substances or substrate. adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. capillary action occurs when the adhesive force to the vessel wall is stronger than the cohesive force between water molecules. capillary action mimics the transfer of water from a tube or pipe. in this way water utilizes its property to transfer water from down to top level of the plant.
