When automobiles are designed, engineers try to maximize their fuel efficiency. Even with modern technology, today's most efficient vehicles can only attain about 30% efficiency. That means of all the chemical energy of the fuel put into an automobile, only 30% of the fuel results in car motion. Which statement best explains why this happens?(1 point)

Jay wants to know how the amount of acidity in rainwater influences the weathering rate of limestone. To answer his question, Jay performs an experiment in which he soaks identical pieces of limestone in 200 mL of different carbonic acid solutions. The pH of the solutions range from 3.0 to 5.5. After performing his experiment once, he reports his data and draws a conclusion. What can Jay do to improve the reliability and accuracy of his data?(1 point)

At one time, all living organisms were separated into only two kingdoms—Animals and Vegetables. Once the microscope was invented and improvements in microscopy were made, however, more kingdoms were defined. The Protist kingdom was established in 1866, and the Monera kingdom was added in 1938.The Monera kingdom was later subdivided into the Eubacteria and Archea kingdoms in the1990s. Fungi were classified as plants until 1969. What is one reason why fungi were separated into a new kingdom?
