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

Introduction The moons surface is riddled with craters‚ formed by many asteroids smashing into its surface. These crater differed greatly in size‚ making it easy to assume that the larger the asteroid‚ the larger the crater. While this is partially true‚ it is not the only factor that controls crater size. This experiment will be exploring the asteroids speed and how this effects a craters size. Aim This scientific experiment was conducted to find how the impact speed/energy of an asteroid affects

Isabel Wilkerson’s The Warmth of Other Suns: The Epic Story of America’s Great Migration delves into the great exodus of Southern blacks to the North from World War I to the 1970s. While this in an already acknowledged period of Southern and American history‚ the book is still an important source in Southern studies. For one‚ the book provides students with three extensive firsthand accounts of the period‚ something they may not have been exposed to before. Meanwhile‚ some may argue that since a

Next I will pour the Zinc into the test tube containing CuSO4. 3.Finally I will measure the final temperature using a thermometer and record the temperature rise in °c. (I will carry out all my experiments under lab safety precautions.) Variables *I will vary the mass of Zinc‚ & use the following Zinc weights: 0.5g‚ 1g‚ 1.5g‚ 2g and 2.5g. *I will repeat each experiment twice for an average. For a fair test I will need to control

In our experiment‚ we will be testing three different proteins to see if they denature at the same temperature. A protein is a molecule containing amino acids created in ribosomes that have many functions‚ including being an enzyme and transporter‚ structuring‚ translating genetic information‚ and serving as a channel for charged molecules to pass through the cell membrane. As a molecule‚ a protein is shaped like a coil (Food Science Basics 2014). Denaturation is when a protein’s shape changes due

evaporates‚ it lowers the temperature of the substances around them‚ because evaporation is an endothermic process. In the graph‚ each substance has a different curve. Some lowered the temperature much more than others. This is because different substances require differing amounts of energy to evaporate. To test this‚ the temperature change from the evaporation of 4 different alcohols was measured and compared‚ along with cyclohexane. Methanol had the largest change in temperature‚ 18.9 ºC. This indicates

Explainthe relationship between the average cost and marginal cost curve? Answer: We usually assume that the Average Cost curve is U shaped The MC curve will intercept the AC curves at its minimum point. When AC is decreasing‚ MC lies below AC - because when MC is below AC‚ producing an extra unit of output will pull down average cots When AC is increasing‚ MC lies above AC - because when MC is above AC‚ producing an extra unit of output will raise average costs Therefore MC will intercept the

Grains → According to my 3-Day Average Food Groups report‚ I consumed no whole grains. MyPlate recommends eating minimum of three grains of whole grains daily‚ and it is recommended that people of my gender and age eat six ounces per day. I could increase my whole grain intake by eating whole grain cereal (when I do eat them) and using whole grain types when I am cooking pasta or rice. Some obstacles for achieving this goal includes time and money. As a student I lack time to make a trip to the grocery
