(03.01 LC)While some mutations can benefit an organism, others are harmful and can lead to cancer. Which of the following best describes how mutations can cause cancer in an organism?

(01.01 HC)Several groups of researchers conducted experiments to study how students’ diets affected their performance in school. Researchers asked students to record what they ate every day for a year. The findings suggested that students who ate a higher amount of vegetables as compared to protein tended to have better grades. What can the researchers validly claim based on these findings?

(02.03 MC)Plant and animal cells differ in shape. Plant cells are usually box-shaped, while animal cells tend to be irregularly shaped. Which of the following comparisons correctly identifies the reason for this difference?

(01.01 HC)Jordan has an organic garden. He is designing an experiment to determine if a mineral-oil bug spray made of garlic and habanero peppers is more effective on Japanese beetles than one made with just garlic. How could Jordan improve his plan for the experiment as outlined below? Prepare bug sprays, being sure to document ingredients in each type Determine which plants will be sprayed and section off two groups Spray every morning at 8:30 am Record number of beetles on each group at the same times every day Record significant rain or weather events that may affect application of the sprays Photograph damage on both groups of plants at the end of the trial

(02.05 MC)A swimmer sprints a short distance for a competition. The swimmer is not able to take in enough oxygen to make the ATP needed for the sprint. Which of the following processes is most likely going to occur in the swimmer’s muscle cells during the competition?
