Question
Passage IV and As a banana external peel changes color the chemical composition of the pulp Three experiments were performed to study the ripening of bananas 12 Experiment On Day 0. 100 bananas were harvested the same banana plant. All the banana peels were completely green. so average peel color "completely green was assigned to the group. Next, the bananas were stored under ripening conditions (6 and 85% relative the next 28 35 days. Every 7 days during that time period, the bananas were inspected and a new average peel color was assigned. Figure 1 The relationship between average peel color and time is shown was on each day that the mass of the in and determined. the sugars further analyzed, mass, the 3 determined (see Figure 2). sucrose in the sample was Table 1 Day Average peel color fructose completely green 7 green with yellow streaks 14 yellow with green tips 21 completely yellow ellow with brown spots Experiment 2 On each day that an average peel color was assigned, the following procedures were also performed: First, 3 bananas were randomly selected from the group and peeled. Then, the pulps of the 3 bananas were thoroughly mixed together, and a 100 g sample of the pulp mixture Figure 2 was collected. Next, an 80% solution of ethanol in H20 (by volume) was mixed with the sample to extract the starch Table and figures adapted from R. C. Adao and M. B. A. Gloria, and the sugars from the sample. Then, the mass, in g, of the "Bioactive Amines and Carbohydrate Changes During Ripening of starch in the sample and the mass, in g, of the sugars in the "Prata" Banana (Musa acuminate x M. balbisiana)." C2005 by sample were determined (see Figure 1)Explanation / Answer
21) From figure 2 it is clear that fructose and glucose contents increase gradually, Option A
22) From day 21 the bananas get completely yellow, so from fig 1 (starch) the mass of starch in the
sample will be close to 4gm, Option G
23) Day 14, Option B
24) Option H is the answer
25) option B is the answer
26) % Volume of ethanol in solution = ( 80mL of ethanol / 80mL of ethanol+20mL of H2O) * 100
Option J is the answer
27)Option C
