The word “cumulative” means that something builds on itself. which example best shows how scientific knowledge is cumulative?

watson and crick worked together to come up with the model of dna.
kepler based his laws of planetary motions off of newton’s law of gravity.
hardy and weinberg independently came up with a population equation.
darwin and his grandfather both worked on the ideas of survivability.

Kepler based his laws of planetary motions off of Newton’s law of gravity.

Explanation:

As the statement tells us, cumulative means that something gets bigger, by succesive additions. For scientific knowledge, this would mean that new knowledge is built upon laws or theories that were already stated before.

For example, Newton established his law of gravity, then, years later, Kepler established his laws of planetary motions, using principles that Newton wrote in his law of gravity.

why is arctic sea ice important? arctic sea ice keeps the polar regions cool and moderate global climate. sea ice has a bright surface; 80 percent of the sunlight that strikes it is reflected back into space. as sea ice melts in the summer, it exposes the dark ocean surface.

water at room temperature is flowing through a pipe with pressure taps located 10 ft apart along one section of the pipe, which are connected to a mercury (s=13.6) manometer.
