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.
Typically glycolysis. Glycolysis is a process by which sugars (specifically glucose) is broken down into ATP (energy). There are, however, many pathways to derive energy from differently moleculs (including lipids and carbohydrates).
Answer:
Girls have two X chromosomes and boys have chromosomes (XY).
Explanation:
Girls have two X chromosomes (XX), and boys have one X and one Y chromosome (XY). Whether a baby will be a boy or a girl is determined at the time of conception.
The answer is A. Man-made
Stomata are tiny pores present in the leaf that allows gas exchange and is where water vapour leaves plants and carbon dioxide enters. Special cells called guard cells present in the stomata, control each pore's opening or closing. When stomata are open, transpiration rates increase; when they are closed, transpiration rates decrease.
