While researching a topic.a student has taken the following notes: - Puntius javanicus is a species of commercially raised fish. - Researchers in Indonesia recently found that adding pineapple extract to fish food increased both the feed utilization efficiency and the growth rate of P.javanicus. - Adding the pineapple extract did not affect total food consumption. - The researchers thus determined that the increased growth rate resulted from the increased feed utilization efficiency. - The enzyme bromelain in pineapple extract enhances the hydrolysis of ingested proteins. - This allows the fish to more readily absorb them. 27 The student wants to explain how pineapple extract increased the growth rate of P. javanicus. Which choice most effectively uses relevant information from the notes to accomplish this goal? A Researchers in Indonesia recently found that adding pineapple extract to fish food increased the growth rate of P. javanicus. B An enzyme in pineapple extract, bromelain increased the growth rate of P. javanicus by enhancing the hydrolysis of ingested proteins,in turn affecting the fish's total food consumption. C i the growth rate of P.javanicus was affected not by food consumption but by feed utilization efficiency. D The enzyme bromelain enhanced R javanicus's absorption of ingested proteins, increasing the growth rate of fish fed pineapple extract.

## Step 1The problem is asking us to choose the most effective explanation for how pineapple extract increased the growth rate of P. javanicus. We need to consider the information provided in the notes and choose the option that best explains this.## Step 2Option A only states that researchers found an increase in the growth rate of P. javanicus when pineapple extract was added to the fish food. However, it does not explain how the growth rate increased.## Step 3Option B suggests that the enzyme bromelain in pineapple extract increased the growth rate by enhancing the hydrolysis of ingested proteins. However, it incorrectly states that this affected the fish's total food consumption.## Step 4Option C correctly states that the growth rate of P. javanicus was affected not by food consumption but by feed utilization efficiency. However, it does not explain how the feed utilization efficiency increased.## Step 5Option D correctly states that the enzyme bromelain enhanced P. javanicus's absorption of ingested proteins, increasing the growth rate of fish fed pineapple extract. This option effectively uses the relevant information from the notes to explain how the growth rate increased.
