PLEASE PLEASE PLEASE! Katie is researching the evolution of dinosaurs, which thrived during the Triassic, Jurassic, and Cretaceous periods, and the evolution of mammals, which thrived in the periods that followed. To support certain claims about her research topic, Katie cites the graph shown below. Sort the claims according to whether the graph provides evidence to support them.

the graph supports: background extinctions, mass extinctions affected the evolution of mammals and dinosaurs

The graph does not support:both mammas and dinosaur revolved in the pattern of gradualism, dinosaurs evolved by adaptive radiation, and convolution affected the evolution of mammals and dinosaurs

Explanation:The graph only shows mass extinctions and background extinctions

when atoms of different types of elements join together, they make molecules called compounds. water consists of compound molecules made up of 2 hydrogen atoms and 1 oxygen atom. this is why it's called h2o. water will always have 2 times the number of hydrogen atoms as oxygen atoms.

oxygen +1 most likely
