A continuous process is set up for treatment of wastewater. Each day, 10³ kg cellulose and 105 kg bacteria enter in the feed stream, while 10² kg cellulose and 1.5 x 10² kg bacteria leave in the effluent. The rate of cellulose digestion by the bacteria is 8 x 10² kg d^-1. The rate of bacterial growth is 4x 10² kg d^-l; the rate of cell death by lysis is 6 x 10² kg d^-1. Write balances for cellulose and bacteria in the system.

sap is translocated from areas of supply, called sources, to areas of metabolism or storage, called sinks. Which of the following statements about source and sink are TRUE?

a.) Sinks include any nonphotosynthetic organs of the plant and organs that do not produce enough photosynthetic products to support their own growth or storage needs

b.) Sources include exporting organs that are capable of producing photosynthate in excess of their own needs

c.) During the growing season of the first year, storage root is a sink, when it accumulates sugars received from the source leaves. During the second growing season the same root becomes a source

d.) Roots, tubers, developing fruits, and immature leaves, which must import carbohydrate for normal development, are all examples of sources tissues

Find the correct combination of the source and sink pattern of translocation.
