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.

What is unique about the members of the group of fungi to which penicillium notatum belongs? they are not important for medicine. they are not made up of hyphae. they are used in fermentation. they lost the reproductive phase.

2. if scientists identify an animal with bilateral symmetry and no segmentation, which phylum can it definitely not belong to? a. roundworms b. annelids c. mollusks d. flatworms

Consider the motion of the balloon and its air contents in terms of momentum. in step 1 above, the total momentum of the balloon and its contents was zero. recall that momentum = mv. both the balloon and the air inside it had a velocity of zero and therefore the total momentum was zero. now think about what happened when the air escaped from the balloon. a certain mass of air accelerated in one direction. in order to keep the total momentum of the system zero, the balloon itself (which has mass) had to accelerate in the opposite direction. use this scenario to you explain why the soda can rotates when the water squirts out of the escape holes. what was your hypothesis concerning the water-filled can? according to your data, do you think your hypothesis was correct? (be sure to refer to your data when answering this question.) summarize any difficulties or problems you had in performing the experiment that might have affected the results. describe how you might change the procedure to avoid these problems. give at least one more example of newton's third law in everyday life.
