Examine the micrograph of the yeast cells. the scale bar under the photo is labeled 1μm. the scale bar works the same way as a scale on a map, where, for example, 1 inch equals 1 mile. in this case the bar represents a much smaller distance. using the scale bar as a basic unit, determine the diameter of the mature parent cell and the new cell. start by measuring the scale bar and then each cell diameter. the units are irrelevant, but working in millimeters is convenient. divide each diameter by the length of the scale bar and then multiply by the scale bar’s label to give you the diameter in μm.

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.

i believe it is "they are not used up by reactions" as the answer to your question, text me back if this is correct because i just learned this.

i think it is d. objects resist changes in their state of motion.
