are organisms that have a limited ability to control their body temperature. Their cellular activities generate little heat. Their body temperatures rise and fall with ambient temperature changes. Most organisms are ectotherms. Examples are plants‚ all invertebrates‚ fish‚ amphibians and reptiles - ENDOTHERMS are organisms whose metabolism generates enough heat to maintain an internal temperature independent of the ambient temperature. Examples are birds and mammals - EXTENSION (Not really needed

How can the specific heat capacity of water be used to regulate temperature? Specific heat capacity is the amount of energy needed to increase the temperature of an object by 1˚C. The formula that uses specific heat is Q = mc∆T‚ where Q is heat energy‚ c is specific heat‚ and ∆T is the change in temperature. The amount of heat energy depends on the mass‚ or the size of an object‚ and the specific heat capacity‚ which depends on the substance it is made from. The specific heat capacity of water

Hypothesis: Temperature of water affects the time taken for salt to dissolve Introduction: In this is will be doing a coursework an experiment in which I will be trying to prove my hypothesis? I will do a set of trial experiment and a main one which I will be trying different temperature‚ which I can prove that this will work and to make sure I get hang of it when I do my real experiment. I will also draw a set of graphs in which I can show which can show if this proves my hypothesis. Important

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

LAB ACTIVITY: Coastal and Continental Temperature Ranges ANALYSIS: 1) I can tell from the temperature curves that the cities are all in the Northern Hemisphere because it ranges from low to high then back to low again starting in January. 2) The city that has the greatest yearly temperature range is Bismarck‚ N.D. 3) The cause of the greatest range is because the location is located most near the pole. 4) The rates of heating and cooling do not differ much for New York

How does water temperature affect the amount of dissolved oxygen? Ⅰ. Introduction Dissolved oxygen is just one of the many ways to measure water quality. It means the volume of oxygen that is contained in water. The amount of dissolved oxygen in water usually determines the quantity of organisms living in that water. Dissolved oxygen levels vary by how much oxygen the water can hold‚ how much oxygen is produced by photosynthesis‚ and how much oxygen is consumed by respiration. If water is too warm

2 Angles make a difference Aim The aim of this experiment is to test whether the angle of sunlight affects the surface temperature on earth. Hypothesis I believe Block B will receive more sunlight than Block A‚ because the lamp shines directly onto Block B. Materials * * Lamp * 2 thermometers * 2 blocks of wood * Black plastic tape Procedure 1. Cut out two small identically sized pieces of black tape and attach onto wooden blocks so that they make pockets. 2.

After performing this experiment‚ it was found that the surface the chocolate was placed on could make a major difference. The hypothesis that was made had mostly incorrect predictions‚ but with some correct ones. It was found that using the palm of one’s hand was the best surface on which to melt chocolate‚ as was predicted. It melted so far‚ and so fast‚ that the experiment had to be altered. Coming in second place was the surface of black paper‚ something that was not expected. The black
