Chemistry All about matter There are three different stages of matter: Solid‚ Liquid and Gas Solid (s): Have a certain volume and shape. “Particles” are arranged in a specific crystalline patter and they only vibrate around fixed positions. Liquid (l): Have a fixed volume‚ but not shape. The particles have some freedom and can move around each other. They collide often. Gas (g): Doesn’t have a fix volume or shape. (Takes up the space where it is) Particles move freely in all space available

6.1.1 Explain why digestion of large food molecules is essential. There are two reasons why the digestion of large food molecules is vital. Firstly‚ the food we eat is made up of many compounds made by other organisms which are not all suitable for human tissues and therefore these have to be broken down and reassembled so that our bodies can use them. Secondly‚ the food molecules have to be small enough to be absorbed by the villi in the intestine through diffusion‚ facilitated diffusion or active

The death penalty is unjust and inhumane for nations to carry out. In addition‚ it is irrational for the United States government to choose to condemn an individual to death. The death penalty should be banned. The main reasons the death penalty must be eliminated is for the inequality of race‚ gender‚ and class.

In 2010‚ only one country‚ Gabon‚ abolished the death penalty for all crimes. During 2010‚ 23 countries executed 527 prisoners and at least 2‚024 people were sentenced to death in 67 countries
