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

In the laboratory setting, selection for a trait in fruit flies Blank______.Multiple choice question.has had mixed responses (as predicted for some traits but not for others)has consistently lead to a strong, predictable evolutionary responsehas never achieved a consistent, predictable evolutionary response

How does artificial selection contradict the claim that selection can only produce minor evolutionary change?Multiple choice question.Artificial selection has produced many new species of plants and animals.Industrial melanism can be reversed within 20 generations.Variation in bristle numbers among different populations of artificially selected fruit flies does not overlap after about 35 generations.Differences between breeds can be larger than differences between different genera of animals or plants.

Experiments with fruit flies have shown that significant evolutionary change can be observed within Blank______.Multiple choice question.1-2 generations35-40 generationsno fewer than 100 generations

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

What did Darwin study in his research of artificial selection?a. Dogs and catsb. Farm and pet animalsc. Birds of preyd. Insects
