Difference Between Prokaryotic and Eukaryotic Cells, Finding Angle Measurements, Main Idea, US Civil War

To find the difference between prokaryotic cells and eukaryotic cells, all you need to see if the DNA or RNA is inside a nuclear membrane. If it is, then it's a eukaryotic cell. If you can't see the genetic material, then you usually can tell from whether or not it has flagella since most prokaryotic have flagella.

To find the measurements of angles, you can usually make triangles at the areas where you know the measurements then calculate to get the answer since all shapes can be formed from triangles and all triangles' interior angles add up to 180 degrees. When you have two parallel lines and a third intersecting line, you can easily use logic and the number 180 to solve it in degrees. In the screenshot below the answer is 180 - (105+54) = 21.

The main idea is what the passage such as an essay or paragraph is about. For example, the topic of this paragraph is "main ideas" and the main idea is "the main idea is what the passage such as an essay or paragraph is about". The main idea of can be found at any part of a passage and is considered a main idea when it is reinforced by evidence or proof on why the main idea is true.

The Civil War started in 1860, when 11 states in the southern side of the US left the country and made their own country known as The Confederacy. The states that stayed in US were called The Union. Eventually, The Confederacy lost and the war was over at April 9, 1865. It lasted 5 years and ended five days before Abraham Lincon was assasinated during a play in Washington DC. He was assasinated because John Wilkes Booth was mad about The Confederacy losing the war.
