Bacteria Prac Aim: To observe the growth of bacteria on Agar plates Hypothesis: That the bacteria will grow in colonies throughout the agar plates except for the one with the anti-biotic loop because some will fight off the bacteria. Method: (Method taken from prac sheet) Plate 1: Use the swab to cover your entire agar plate in your bacteria. You only need one swab of bacteria but be careful to cover the entire surface of your agar in a layer of bacteria. Carefully place an Antibiotic Mastring

To investigate the habitats woodlice prefer is dark condition or wet condition 1. Use a shoebox and place some soil and dry leaves in it. Start looking under rocks or bricks for some woodlice and place them in the shoebox. Make sure the soil is placed enough and evenly to keep the woodlice happy when not under investigation. * 25 woodlice were used for the experiment because the more woodlice used increases the statistics of which condition the woodlice prefer and give a more accurate data

2.6 Kinetic studies of prepared complexes The integral method of Coats–Redfern equation[19‚21‚27‚38] was used for determining the kinetic parameters of the decompositions process for the investigated metal complexes according to following equation: log[log(w_∞/(w_∞-w))⁄T^2 ]〖=log[AR/〖∅E〗^* (1-2RT⁄E^≠ )]〗-E^≠/2.303R 1/T (4) Where w_∞ is the mass loss at the accomplishment of the decomposition reaction‚ w is the mass loss at temperature T‚ ∅ is the rate of heating and R is

Erin Annabell INTRODUCTION The ecological niche of the Porcellio scaber: The Slater belongs to the biological class Crustacea. The slaters studied were found in damp‚ cool‚ humid conditions. They are most easily found in spring and autumn. The most common site around the home is on compost heaps or under shelter such as bark‚ wood piles and boards left in shaded‚ moist conditions. They may also be found in deep‚ damp soil litter under the shelter of bushes or trees. So that they were not exposed
