- Q1Which question could best be answered with her experiment?Question 1: Why did the water level in the test tube go down?Question 4: Would a different type of plant change the water level in the test tube?Question 2: Is light needed to change the water level in the test tube?Question 3: Did light cause the water level in the test tube to go down?60s
- Q2What is the dependent variable in the student's experiment?the type of plant in the test tube.the amount of timethe amount of lightthe water level in the test tube60s
- Q3#3 What is the main substance found in the top part of the test tube labelled X in figure 2?Oxygennothingwater vaporcarbon dioxide60s
- Q4Prior to starting the experiment, the biologist needed to fill out paperwork explaining procedures for using and caring for the fish in his experiment. What is the purpose of this paperwork?to determine whether all of the fish were of the same species and age.to verify that his sample size will be sufficient for meaningful results.to ensure that his research animals will be treated humanelyto document procedures so his experiment can be reviewed or repeated.60s
- Q5What information is least relevant to understanding this experiment?the type of clear divider used to separate fish.the time if took the trout to move to the back of the tank.the number of fish in each tank.the location where the trout were raised60s
- Q6Which of the following statements is the basis for the hypothesis that was tested?"The biologist thought that fish raised in hatcheries lost their fear of predators. ""The biologist found that the hatchery fish moved away much slower than the wild fish.""To test the idea, he placed 15 young hatchery trout and 15 wild trout of the same age and species into two separate but identical tanks""A fish biologist wondered if fish raised in hatcheries would be able to survive in the wild environment.60s
- Q7Which of the following changes should Teresa make to better communicate results?Include a legend that shows the type of solution used.Scale the y-axis to end at the greatest respiration rate (94mL)Label the x-axis to display the time in increments of five.Add units to the label of the independent variable.60s
- Q8An entomologist collected 5 samples of insects from a large puddle. The table shows the collected data. Which of the data displays BEST represents the distribution of insects collected from the puddle?B- Line graphD- Pie chartA- Bar GraphB- Bar Graph60s
- Q9Which list shows different levels of organization within a population ordered from least to most complex?organisms, organ systems, organs, organelles,organ systems, organs, organelles, organismsorgans, organelles, organisms, organ systems.organelles, organs, organ systems, organisms60s
- Q10Jim collected owl pellets in a field near his home then dissected them. The following table shows the frequency of mice found in the collected owl pellets. What is the mean number of mice per owl pellet?3.33.02.02.460s
- Q11A professor of molecular biology has completed an experiment on mutations. The results indicate that the current understanding of how mutations occur is incomplete. Which is the most appropriate way to share results of this experiment?Send the results to newspapers and magazines.Share the results with class of university students.publish the results in a scientific journalhold a press conference60s
- Q12A fertilizer company claims that their fertilizer causes rose bushes to produce new flowers. To support this claim, they set up an investigation. They added the recommended amount of fertilizer to 100 rose bushes in a greenhouse, and then they counted the number of flowers that developed on each plant. The number of flowers on each rose bush ranged from 28 to 36. The mean number of flowers on each plant was 33. A gardener was skeptical of the company's claim. Which statement provides the BEST reason to be skeptical?The investigation was conducted only on rose plants.The research was conducted without a control.The investigation tested only one variable.The sample size was too small to be valid.60s
- Q13Which of the following statements about scientific theories is NOT correct?Theories are inferred explanations, strongly supported by evidence.Theories explain a range of observations and are used to make predictions.Theories have been tested many times.Theories are incomplete, temporary ideas.60s
- Q14What is one way that copyrights on scientific literature hinder scientific advancement?Experiments or research projects are not able to start on sign.Background research for experiments is more complex.Scientists are protected so other labs or companies can't steal their ideas.Paying for copyright use increases the amount of funds available to do research.60s
