Explain why Archimedes is considered one of the fathers of the scientific method?
V125BC [204]

Archimedes was an ancient Greek mathematician and inventor. He made mathematical discoveries as he solved everyday problems. He invented machines to move heavy objects, carry water, and fight battles. Archimedes recorded his discoveries so that others could learn from them. Today he is considered one of the greatest mathematicians of all time.

Archimedes was born in the Greek city-state of Syracuse, Sicily, in 287 bc. His father, Phidias, was an astronomer. Archimedes also studied astronomy.

It is believed that Archimedes visited the famous library of Alexandria, Egypt, where he met great scholars. While in Egypt, he is said to have invented a machine to carry water upward from one level to another. The machine, known as Archimedes’ screw, is still used in parts of the world today.After studying in Alexandria, Archimedes returned to Syracuse. He wrote many works to explain his discoveries. Archimedes’ most-famous ideas include his explanations of how levers and pulleys can lift and move heavy objects. Another idea, called Archimedes’ principle, is a scientific law. It describes what happens when an object floats in water.

In 213 bc Romans attacked Syracuse. Archimedes invented machines to defend the city. When Syracuse was finally overtaken, Archimedes was killed there in 212 bc.

Eutrophication how can aquatic ecosystems change over time pogil answers
rosijanka [135]
Eutrophication is a process that leads to enrichment of ponds, lakes and any water body with minerals such as nitrogen and phosphorus. Aquatic ecosystems are diverse and consists of phytoplanktons, zooplanktons, fish and other animals. Too much enrichment of the ecosystem adversely effects the flora and fauna of the aquatic bodies. Eutrophication leads to more uptake of oxygen and increases biological oxygen demand of water. With less oxygen available for animals inside the aquatic systems, they might began to die. Eutrophication is a result of human activities and must be minimized for the betterment of aquatic bodies and aquatic animals. Thus, eutrophication might lead to destroy the aquatic bodies over a period of time.

During which period did humans first appear on Earth? Quaternary Neogene Paleogene Cenozoic
anyanavicka [17]

The answer is Neogene

Explanation:

It cannot be Cenozoic because that is an era. Not a period. Paleogene, Neogene, and Quaternary (our current period) are all periods within the Cenozoic Era (our current era). On the geologic time scale, there are Eras, Periods, and Epochs (and a few more classifications). Humans first appeared in the Miocene epoch which is an epoch in the Neogene period (in the Cenozoic era).

This is why the answer is Neogene.

Hope this helps...

why might changes to the gulf coast prairies and marshes ecoregion happen more quickly then to other ecoregion?
liq [111]
The reason for this is because it is closer to water, therefor they have more events that could happen. Also there is a lot of weathering, erosion, and deposition which makes the gulf coast prairies and marshes more susceptible to changes. 

I hope this helps!
