The effect of drugs‚ toxins‚ and other molecules on synapse and synapse transmission. The synapse is the small gap separating two neurons‚ the presynaptic neuron (neuron that carries the impulse to the synapse‚) and postsynaptic neuron (neuron that carries the impulse away from the synapse.) It separates the axon terminals of the presynaptic neuron from the postsynaptic neuron. The synapse is made of three major parts: a presynaptic neuron‚ a postsynaptic neuron‚ and a synaptic cleft. The presynaptic

Trace the development of the bullying. How convincing are the situation and Elaine’s feelings are portrayed. -How it changes and increases We are first introduced to Cordelia and prepared for the future conflict between the two girls when it is mentioned‚ "The third girl doesn’t wave". This lack of warmth towards Elaine is a premonition of what is to come‚ and is at the same time believable- new girls are often wary of each other‚ uncertain of what the other will be like. This key moment also

Problem This study aims to determine if the color of light affects the amount of oxygen created through the process of photosynthesis by Hydrilla‚ an aquatic plant. It specifically seeks answer to the following problem: 1. Which color of light affects the evolution of oxygen as sign of photosynthesis? Hypothesis The following hypothesis will be tested in this study: 1. Hydrilla will produce the most oxygen when exposed to certain color of light. Significance of the Study The study is

Lab #5: Dissolved Oxygen Lab Be sure to read and understand the below instructions BEFORE the lab! Experiment 1: Investigating the Effect of Temperature and Salinity on the Concentration of Dissolved Oxygen in Water Introduction: In an aquatic environment‚ oxygen must be in a solution in a free state (O2) before it is available for use by organisms (bio-available). Its concentration and distribution in the aquatic environment are directly dependent on chemical and physical factors and are

curve Shift to the right: decreased hemoglobin affinity for oxygen exists; therefore oxygen is more readily released to the tissues. Can be caused by acidemia‚ increased temperature‚ anemia‚ chronic hypoxemia‚ and low cardiac output states. When conditions exist where the curve has shifted to the right‚ the PaO2 is higher than expected at the normal curve. Shift to the left: hemoglobin affinity for oxygen increases and hemoglobin clings to oxygen. Can be caused by alkalemia‚ decreased temperature‚ high

Decomposition of Sodium Chlorate to Create Oxygen Gas Introduction: There are several types of chemical reactions. Those reactions include synthesis‚ decomposition‚ single replacement‚ and double replacement. In this experiment‚ we will be decomposing sodium chlorate to create oxygen gas. In a decomposition reaction‚ a chemical compound is being separated into elements or simpler compounds. AB → A + B is a simple way of expressing what happens in a decomposition reaction‚ AB break down into A

From Water to Land (Revision) Abstract: The early tetrapods were the first vertebrates to actually walk the solid earth. They began their conquest of land in the Paleozoic era around 360 million years ago. The question many paleontologists have been asking for a long period of time is whether the anatomy for locomotion on land was developed in water for swimming purposes‚ or if it was adapted after the creatures became terrestrial. Recent findings of fossils indicate that the transformations

Cellular Respiration  Cellular respiration is the process of oxidizing food molecules‚ like glucose‚ to carbon dioxide and water. C6H12O6 + 6O2 + 6H2O → 12H2O + 6 CO2 The energy released is trapped in the form of ATP for use by all the energy-consuming activities of the cell. The process occurs in two phases: glycolysis‚ the breakdown of glucose to pyruvic acid the complete oxidation of pyruvic acid to carbon dioxide and water In eukaryotes‚ glycolysis occurs in the cytosol.
