biological field and it helps ensure the survival of an organism. It does so by converting things like food that we ingest into energy via a series of somewhat complex biochemical reactions. This energy can then be used for a multitude of things including growth‚ blood circulation‚ body movement‚ etc. When this energy is used O2 consumption and CO2 production are necessary due to O2 being our terminal electron acceptor. With that being said‚ metabolism is not a set characteristic within the human body. It

Using the three testtubes with spores‚ the first one (1) was autoclaved‚ the second (2) was boiled‚ and third (3)received no treatment. The fourth test tube (4) didn’t have a spore strip and served as a controlfor the effectiveness of the aseptic pipetting technique. As hypothesized‚ test tubes 1 and 4experienced no bacterial growth.

Stoichiometry lab 1 Purpose: The purpose of this lab is to find the limiting reactant‚ also to find the percentage yield and percentage purity of the reaction that happens between Calcium Chloride and Sodium Carbonate. The other purpose was to know how the reaction can be balanced and created. Hypothesis: In this lab we are going to see a precipitation reaction. This is a reaction where two soluble salts Sodium Carbonate and Calcium Chloride are added together and the result is the precipitation

Formal Scientific Lab Report Osmosis Katy Hunter 10-26-2012 Abstract: The objectives of this lab was to be able to create models of cells with the dialysis tubing to show us how the plasma membrane is selectively permeable‚ to study the effects of osmosis on a model cell‚ and to foresee the effect of solute concentration on osmosis. In order to achieve these objectives‚ we had to fill the dialysis tubing with either water‚ or different amounts of sucrose. We then tied off the tubes and put

Therefore four types of acid-base titrations are possible: strong acid-strong base‚ strong base-weak acid‚ weak acid-strong base and strong acid-weak base titrations.

An acid-base indicator is a substance‚ which changes colour with

biochemical reactions1. Enzymes are responsible for almost every reaction that occurs in a cell and is named according to the substrate they specifically affect. An enzyme works best under optimal conditions pertaining to temperature‚ pH level and salt concentration1. In unfavorable conditions enzymes will become denatured and ineffective. In human beings enzymes are most effective in 37 C temperatures‚ at a pH level of 7.2 (in the stomach a pH of 2 and in the small intestine a pH of 8.5)3 and with
