Tyler Cowan Professor Foltz Biology 181 April 8th 2015 Lab Report: Respiration Abstract: The objective of this lab was to figure out which has a higher cell respiration rate between crayfish and elodea. In order to figure this out we first set up three beakers to represent our control‚ elodea and crayfish and filled them with 75mL of culture solution which were dechlorinated making the solution acidic. We then had to place both the elodea and the crayfish in separate beakers filled with 25mL of

THE INTERPRETATION OF THE POSITIVE VENOUS PULSE.* ALBION WALTER HEWVLETT‚ M.D. (Assistant Professor of AMedicine at thze Cooper Medical College‚ San Francisco‚ Cal.) INTRODUCTION. The normal venous pulse is characterized by the presence of two main waves. The first of these‚ the a wave‚ is due to the contractioni of the right auricle‚ and immediately precedes the carotid pulse. The other‚ or v wave‚ appears in the neck in early diastole coincident with the closure of the semilunar valves

Living things get energy to do things through photosynthesis‚ food molecule breakdown‚ build up‚ storage‚ and lastly cellular respiration. All of these ideas are the reason that myself and others have energy to do anything and everything. Photosynthesis is one way plants(plants are the main source of energy for all things)get energy to do things. The reactants of this are water‚ carbon dioxide‚ and although light energy is not a reactant‚ it is necessary once the energy from the seed is gone. Carbon

action is coordinated by the hypothalamus. In Module 2 we saw how the breathing and heart rates were maintained (N.B. Synoptic questions probable!). Here we shall look at three more examples of homeostasis in detail: • temperature‚ • blood glucose and • blood water. All homeostatic mechanisms use negative feedback to maintain a constant value (called the set point). This is the most important point in this topic! Negative feedback means that whenever a change occurs in a system

The Blood/Circulatory System Anatomy & Physiology I March 18‚ 2013 The blood system is part of the circulatory system. I am going to be focusing on the blood and the diseases which affect the blood. The blood‚ heart and blood vessels form the cardiovascular system which links the body’s internal and external environments together‚ by transporting substances between the two. Blood is a type of connective tissue that carries nutrients‚ oxygen and wastes through the body. Blood cells are formed

cannot be used as directly by cell as a source of energy so cells use ATP as their immediate source of energy. * This conversion of glucose into ATP takes place during cellular respiration and there are 2 different forms of cellular respiration depending upon whether oxygen is available or not * Aerobic respiration requires oxygen and produces CO2‚ water and lots of ATP. * Aerobic has 4 stages: 1) Glycolysis – the splitting of the 6-carbon glucose molecule into 2 3-carbon molecule

AUTOMATIC TEMPERATURE CONTROLLED FAN H ere is a circuit through which the speed of a fan can be linearly controlled automatically‚ depending on the room temperature. The circuit is highly efficient as it uses thyristors for power control. Alternatively‚ the same circuit can be used for automatic temperature controlled AC power control. In this circuit‚ the temperature sensor used is an NTC thermistor‚ i.e. one having a negative temperature coefficient. The value of thermistor resistance at

Temperature and Thermometers The Temperature of an object is a measure of the hotness or coldness of that object. An alternative way to think of temperature is to say that “the temperature of an object is a number – on some manmade scale – that indicates the hotness of the object”. ‘Hotness’ in turn is a measure of the kinetic energy of the molecules of the material. Note: You must use the term ‘hotness’.* The SI unit of temperature is the Kelvin (K)* Relationship between degrees Celsius
