molecules from areas of higher concentration to those of lower concentration‚ until there is an even concentration. This movement is random because it is a result of kinetic energy. Diffusion is a slow process‚ but there are many factors that will affect it’s rate. The rate of diffusion will vary depending on the size of the particle. For example‚ a smaller particle will move faster than a large molecule at a given temperature . During reactions‚ when there is more energy‚ the reaction will take place

What I learned in this unit is that the brain is made up of several special parts‚ each of them work in different parts. The brain has many jobs. It controls our spinal cord‚ our central nervous system and our nervous system. The spinal cord carries messages to the brain and also to the nerve cells that carry messages from the brain. Your body senses everything. Like something smashing your toe. You react to it. It all sends itself to the brain and it reacts. The cerebrum‚ controls thinking

capacity to satisfy even the basic human need starts to be compromised (Vitousek‚ Mooney‚ Lubchenco‚ & Melillo‚ 1997).
