Students are setting up an experiment to determine what food source is most beneficial for fruit flies. Students create a choice chamber, shown below, that has two main chambers in it. One chamber is empty, and the other chamber has pieces of banana in it.Created for Albert. All rights reserved.After conducting the experiment, students learned that different food groups may have a different effect on fruit flies.Given the new information, what should the next steps be in this study?Elimination ToolSelect one answerACompare two different types of bananas in the choice chamber.BCompare protein with fats in the choice chamber.CCompare the banana to a protein food source in the choice chamber.DCompare sugar water to regular water in the choice chamber.S

In all cases when scientists have performed artificial selection experiments on fruit flies, a strong and predictable response has been observed.

Given the following choices, select the best hypothesis test to use in this situation.12 participants are randomly selected by their GP to assess the effects of eating fruit on blood sugar levels (mmol/L). Their blood sugar levels were measured for each participant upon entering the trial and again one hour later after eating three pieces of fruit.

In a classic experiment, scientists selected for fruit flies with many bristles on their abdomen by Blank______.Multiple choice question.picking out and breeding the 80% of the population that had the greatest number of bristlespicking out and breeding the 20% of the population that had the greatest number of bristles visually choosing and breeding flies that appeared to have relatively large bristles

Select the factor responsible for the change in the colour and taste the bananas. A moisture B. exposure to air C. keeping it at room temperature D. presence of certain cell components
