    Effect of Substrate Choice On Growth Of Mealworms Abstract: The experiment is designed to show which substrate A or B will better nourish a mealworm. A mealworm was placed in each substrate for a period of seven days and the change in mass from Day 1 to Day 7 was compared. The data was compiled and statistically analyzed. The experiment failed to reject the null hypotheses that there would be no difference in the two substrates regarding meal worm growth

    What effect does temperature have on the oxygen production of enzymes in an animal’s liver? A temperature which is too high would be able to produce little to no oxygen because of the extreme temperature. Just like a temperature too high‚ a temperature which is too low would also produce little to no oxygen for the same reason. Animals that have livers are considered warm-blooded‚ with very warm temperatures; therefore it would make sense for a warm temperature to produce the most oxygen; but one

    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
