All materials used in the eco column have abiotic and biotic factors. All the abiotic factors‚ which are the nonliving things in the eco-column‚ include the water used in the aquatic habitat‚ soil used in the decomposition habitat‚ air‚ and some rocks that were used in the decomposition habitat. The biotic factors‚ which are the living things in the eco-column‚ include the grass and/or the terrestrial plants used in the terrestrial habitat‚ the fish (guppies) used in the aquatic habitat‚ and finally

Proteins are arguably the most important things that people know the least about. As OpenStax CNX puts it‚ “Proteins are one of the most abundant organic molecules in living systems and have the most diverse range of functions of all macromolecules”. Proteins are “Macromolecules that contain nitrogen as well as carbon‚ hydrogen‚ and oxygen”(Miller‚ Kenneth R.‚ and Joseph S. Levine 48). Macromolecules are exceedingly large molecules that can be made up of several lesser molecules called proteins.

Reactions which release energy are described as exothermic and those which absorb energy are endothermic. The energy released in chemical reactions was previously stored as chemical potential energy in the reactants; this stored energy is called enthalpy. The aim of this practical is to observe and classify chemical processes as endothermic or exothermic‚ based on the changes in temperature measured and the observations made. If a chemical reaction produces products with more chemical potential

that atom in a compound. An element’s electronegativity value and other properties affect its oxidation state in different compounds. Decomposition: Some compounds decompose into more than one different element or compound as bonds are broken. Hydrogen peroxide (H2O2)‚ a chemical you may have around your house‚ is stored in a dark container to slow down decomposition‚ which can be caused by heat and light. clues that can indicate that a chemical change has occurred include: production of flames‚ color
