Which of the following is the higher limit of the Chemical oxygen demand of fruit juices ranges from 50g/l ?

Which of the following is the higher limit of the Chemical oxygen demand of fruit juices ranges from 50g/l ? Correct Answer 200g/l

The Chemical oxygen demand or the COD of fruit juices ranges from 50g/l for tomato juice and to 200g/l for apricot juice, 1g of glucose is nearly equal to 1.066g of COD. So, the chemical oxygen demand of the fruit juices is really high.

In tomato plant, red (R) is dominant over yellow (r) for fruit color and purple (P) is dominant over green (p) for stem color. Fruit color and stem color assort independently. The number of progeny plants of different fruit/stem colors obtained from a mating are as follows:
Red fruit, purple stem - 145
Red fruit, green stem - 184
Yellow fruit, purple stem - 66

In a well aerated and agitated microbial culture, the 'supply' of oxygen is equal to 'demand' (uptake) of the growing culture. The KLa for such a system will be (KLa = volumetric mass transfer coefficient, C* = dissolved oxygen concentration in liquid in equilibrium with gaseous oxygen, C = instantaneous value of dissolved oxygen concentration, 'r' = specific oxygen uptake rate per unit weight of cells, X = dry weight of the cells per unit volume)
