Question

Angie designs an experiment to investigate how different types of music affect the height of plant growth. She plans to place the same type of plant in different rooms and play different types of music in each room. Her hypothesis predicts that the plants exposed to rock music will grow the tallest in a given amount of time. What will be the experiment's independent variable? (1 point) the final height of the plants in each room the type of music played in each room the amount of sunlight in each room the type of plants used in each room 12. [01.03] There are several different insecticides sold at your local home and garden store. They all claim to be safe for use around animals and children, but you want to be sure of this safety before you use one of the products at your own home. What would be the best way to increase the scientific reliability of these safety claims? (1 point) Ask an employee of the store for her recommendation. Look up results of tests conducted by environmental agencies. Check for endorsements by celebrities of home-improvement shows. Use the sales records to determine which product is most popular. 13. [01.03] You are researching whether life could have ever existed on Mars. What would be the best choice for scientifically reliable information? (1 point) a book containing information and photos from satellites a NASA article containing data and photos collected on Mars a newspaper article debating the existence of life on other planets an article containing a poll of students at a leading university 14. [01.03] A scientist in Germany published his findings from a scientific investigation that he conducted. Other scientists from around the world conducted similar investigations to test the results. All of the investigations result in similar findings. What does this say about the findings of these investigations? (1 point) They have been proven to be scientific fact because all the investigations gave similar findings. The findings are automatically promoted to a law because they were proven by so many scientists. The results are considered more reliable because they were documented by separate investigations. They are ready to be published in the media and in textbooks as a new scientific theory.

Answer 1

Independent variable would be type of music played

look up results...

(most likely) an article from NASA

the results are considered more reliable :) if you would like an explanation on these answers I would be happy to help
