Teens & Depression. â 1 Depression is a serious problem today and one of the nationâs leading killers of teenaged boys when the number of cases of suicide it generates are factored into the equation.
The first organic molecules were probably very simple carbon-based molecules made of few atoms. These molecules then combined with other simple molecules to form more complex molecules. Over many years and probably trillions and trillions of chemical reactions, more complex molecules, and more stable molecules, formed.
An organic molecule is found in living systems. They are typically composed of carbon atoms in long chains or rings that are attached to other atoms. These other atoms often include elements such as oxygen, hydrogen, and nitrogen. Organic molecules are composed of two or more elements and are produced by or found in living organisms.
