Question
Passage IV and As a banana external peel changes color the composition of the pulp changes experiments performed to study the ripening of Experiment I On Day 0. 100 bananas were harvested from the same banana plant. All the banana peel were completely green. so average peel color "completely green" was assigned to the group. Next, the bananas were stored under ripening conditions 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 Experiment 3 sugars in a was on each day that the mass of the analyzed, and determined. the the 3 further of sucrose in the sample was determined (see Figure 2). Table 1 Day Average peel color fructose completely green 7 green with yellow streaks 14 yellow with green tips 21 completely yellow 28 yellow 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 acum inate x M. balbisiana)." O2005 by sample were determined (see Figure 1)Explanation / Answer
21. the figure 2 shows that the plot of glucose and fructose is increasing linearly but sucrose increased and then decreased. So, answer is glucose and fructose and correct option is A.
22. The color of the peel was completely yellow for day 21 according to table 1. So, the mass of starch for day 21 is 4 g (from figure 1). So, correct option is G.
23. On day 14 in figure 2, the mass of sucrose is in between fructose and glucose. Correct option is B.
24. Option F is correct because the sampleing is done randomly and we suppose that the selected sample is representative of the rest of sample.
25. The sum of the masses of starch and sugar is not equal to 100 g for any day. So, It contained other componenets also including starch and sugar. Thus, option D is correct.
26. Option D is correct formula. 80 % means the sample is 80 % by volume. It means that 80 ml ethanol in total 100 ml solution. 100 ml of solution is comprised of 80 ml ethanol and 20 ml water.
27. It is an osmotic process. So, transfer of water takes place. In graph, mass of starch is decreasing and mass of sugar is increasing. So, option A is correct.
