The graph below is derived from coastal tide and satellite data. It shows how much sea level changed from about 1870 to 2018. Items with pluses (+) are factors that cause global mean sea level to increase, while minuses (-) are variables that cause sea levels to decrease. These items are displayed at the time they were affecting sea level. Graph shows sea levels starting in 1900 and includes events that lead to increases and decreases in sea level. In 1900, sea level change is set to zero. In 1920, sea level rose 20 millimeters. In 1940, sea level rose to 50 millimeters. In 1960, sea level rose to 100 millimeters. In 1980, sea level rose to 125 millimeters. In 2000, sea level rose to 150. By 2020, sea-level rises 200 millimeters. © 2021 NASA's Goddard Space Flight Center According to the graph, melting ice sheets and glaciers combined with thermal expansion as factors increasing sea level rise. What additional variable may have caused the rate of sea level rise between 2000 and 2020? More global dams Refreezing Arctic Ocean circulation Cooler Antarctic

18. which statement about cancer is true?

(me out over the last several centuries, scientists have made the following broad observations while investigating several branches of the life sciences: -the fossil record shows that different types of organisms have existed at different times in earth's history. -many organisms have similar body structures that seem to be adapted to different ways of living in their environment. -organisms of different species often share similarities in stages of embryonic development. -many species share genetic similarities, and almost all organisms use the same basic building blocks to construct proteins. -often, the extent of two species' similarities can be predicted from their geographic closeness to each other. -a great deal of change has been observed among species that have experienced strong selective pressures through many generations. scientists have carefully considered and rigorously tested the observations listed above. when scientists offer a of these observations, they are making 1.) testable explanation, deductive explanation 2.) scientific interference, scientific law
