in the standard plants would increase when less competitors were present and that growth would be more affected by competition than seed pod production would be. The data in Figure 1 and Figure 2 support this hypothesis; the standard plant grew the most when it was in a container alone and‚ on average‚ produced more seeds when no competitors were present (Figure 1). Though growth and seed pod production had similar trends‚ the difference in growth is higher between the single-plant treatment and the

1. INTRODUCTION SilCote aluminum pigment is manufactured by mixing aluminum paste with Monomer‚ SR-350 (trimethylolpropane trimethancrylate) and additive‚ Z-6040 which is an epoxy-functional Silane (3-glycidoxypropyl trimethoxy silane)‚ in a jacketed mixer with the presence of catalyst‚ ABIN (azo-bis-isobutyronitrile). White spirit‚ acts as the carrier solvent in the process. 2. PROCESS FLOW The aluminum paste is first loaded into the jacketed mixer‚ followed by introducing a pre-determined

The light reactions of photosynthesis contain two photosystems‚ two electron transport chains‚ and ATP synthase. These parts are embedded in the thylakoid membranes of a chloroplast. The photosystems contain a collection of chlorophyll molecules. Chlorophyll‚ which is the green pigment of leaves‚ absorbs light energy that excites electrons to a higher energy level. Energized electrons from photosystem I are passed down an electron transport chain and added to NADP+ to form NADPH. Electrons from photosystem

The Effects of Environmental Stimuli on Animal Behavior AP Biology Emily Olsen April 26‚ 2012 I. Introduction: The purpose of this lab is to test the effect certain stimuli has on the behavior of a terrestrial isopod. These bugs are more commonly known as pill bugs and potato bugs. The objective of this experiment is to determine which kinds of habitats potato bugs favor. Potato bugs have an innate behavior called taxis which will cause the animal to move away from a stimulus that is unwanted

Introduction: Plant hormones and growth regulators are chemicals that affect flowering‚ aging‚ root growth‚ killing of leaves‚ promotion of stem elongation‚ color enhancement of fruit‚ prevention of leafing‚ and many other conditions. Very small concentrations of these substances produce major growth changes. All plants produce hormones naturally‚ and growth regulators can be applied by people to are applied to plants by people. Plant growth regulators may be synthetic compounds that mimic naturally

WHAT IS PHOTOSYNTHESIS? 3 Every day the total amount of energy that is captured through photosynthesis all across our planet is equal to approximately 135 terawatts. Now to put this number into perspective the entire human race consumes approximately 15 terawatts of energy daily. This means that there is 9 times more energy being absorbed every day through photosynthesis‚ as there is energy being consumed by all of mankind (Bridges 2008). In order to fully understand photosynthesis

Complete the following questions and submit via Blackboard 1. List two events which occur during prophase of mitosis: 1. An aster is formed by fibers radiating from the centrioles of the cell. 2. Chromosomes are formed when the chromatin threads coil and then condense‚ and these chromosomes are two identical chromatids bound together by a centromere. 2. What is the main occurrence involving the chromosomes during
