Zymomonas mobilis cells are used for chemostat culture to produce ethanol in a 60 m3 fermenter. The yield of biomass from substrate is 0.06 g/g and YP/X is 7.7 g/g. The maximum specific growth rate of Z. mobilis is approximately 0.3 h-1 . The feed contains 12 g/L glucose, and KS for the organism is 0.2 g/L. Assume the culture follows Monod kinetics. Ignore maintenance energy. a. Draw a schematic for the problem. Label all appropriate streams, and list any assumptions.

The nervous system interacts with the endocrine system by a. using hormones as connections b. sending nerve impulses directly to glands c. using neuroendocrine cells as connections d. sending neurotransmitters directly to neurons

Agroup of plant cells was exposed to radiation, which damaged the chloroplasts and caused them to lose function. if the mitochondria were unharmed, what would happen to the overall function of the plant cells? a. the cells would not be able to make food, but would be able to release energy from biomolecules. b. the cells would not be able to replicate dna, but would be able to break down waste. c. the cells would not be able to break down waste, but would be able to replicate dna. d. the cells would not be able to release energy from biomolecules, but would be able to make food.
