Swine Heat Stress ABSTRACT The purpose of this research project is to identify the effects of heat stress on swine. Heat stress is physiological distress caused by excessive temperatures usually over 80-85 degrees Fahrenheit that can result in profoundly adverse effects in swine production. The first phase of this project involves the analysis of these harmful effects on sows‚ gilts‚ and boars. Multiple journal articles will be used to establish these effects. The final phase involves

Tomato Sweetness Jessica Pursell American InterContinental University 01/18/2015 Biology IP2 Introduction You and your neighbor have small kitchen gardens where you both grow tomatoes. His blotchy green and red tomatoes taste much sweeter than your perfectly uniform red ones. Could the sweetness of the tomatoes be effected by the green chloroplasts in the fruit? Hypothesis I personally think that the green chloroplasts do play a part in the sweetness of the tomatoes because it doesn’t

guard cell swells or shrinks due to the gain or loss of water‚ the thickened wall is the only one to maintain its form. Consequently when the guard cells shrink‚ they shift towards each other‚ closing the stomata. Water enters the guard cells by osmosis. The amount and direction of movement of water is influenced by several factors‚ one of which is light. Light has an indirect effect. The guard cells of stomata through which most water loss comes about by transpiration are sensitive to light

Practice Problems Set – 1 MEC301: Heat Transfer Q.1 The slab shown in the figure is embedded on five sides in insulation materials. The sixth side is exposed to an ambient temperature through a heat transfer coefficient. Heat is generated in the slab at the rate of 1.0 kW/m3. The thermal conductivity of the slab is 0.2 W/m-K. (a) Solve for the temperature distribution in the slab‚ noting any assumptions you must make. Be careful to clearly identify the boundary conditions. (b) Evaluate T at the

AP Biology Study Guide Chapter 11 1. Categorize chemical signals in terms of the proximity of the communicating cells. Local signaling – a. Paracrine signaling – a secreting cell acts on nearby target cells by discharging molecules of a local regulator (a growth factor‚ for example) into the extracellular fluid. b. Synaptic signaling – a nerve cell releases neurotransmitter molecules into a synapse‚ stimulating the target cell. Long distance signaling- c. Hormonal signaling – specialized

F6/7 Chemistry Practical: Enthalpy of hydration of copper(II) sulphate Objective: To determine the enthalpy of hydration of copper(II) sulphate Group size: Individual Introduction This experiment enables an approximate determination of the enthalpy of hydration of copper(II) sulphate to be made. The enthalpy change when one mole of anhydrous copper(II) sulphate is dissolved in water is first determined. Secondly‚ the enthalpy of solution of copper(II) sulphate pentahydrate in water is determined

Specific heat is the property of the material that an object is made of. The greater the material’s specific heat and the mass‚ the more energy must be added to change its temperature. The goals of this lab were to calculate the specific heat of water and compare to the known value of 4.19J/°Cg. Another goal was to calculate the efficiency of the hot pot used for the experiment and to estimate the cost to heat water for a cup of tea and to bath in a bathtub. The thermal energy E= cm Δ T‚ required

DNA Aim This practical procedure allows you to amplify a 460 basepair fragment of DNA from within the control region of the mitochondrial genome. This can be done using three water baths or‚ if one is available‚ a thermal cycler (PCR machine). After it has been amplified‚ the DNA is run on an electrophoresis gel. Note: This method has been adapted from one developed by the Dolan DNA Learning Center at Cold Spring Harbor Laboratory. More details are available from the DNA Learning Center’s
