1. The normal rat had the fastest BMR. 2. Because of the different organs that were removed from the two other rats that would produce certain hormones. My prediction was correct. 3. Thyroxine would be missing in its blood. 4. Thyroxine wouldn’t be released which helps maintain metabolism and body. The hormone levels would be lower as a result. 5. The metabolic rate went up.My prediction was correct. 6. It raised the rate‚ even though it wasn’t as high as the normal rat’s‚ it was

Precision and Accuracy in the Laboratory Precision – This is a word used to describe the quality; fact or condition of being exact and accurate.(1) Accuracy – This is a word to describe the quality or state of being correct or precise. (2) AIM: The aim of the practical is to assess the accuracy and precision of three types of pipette. Abstract: In this experiment‚ I am going to be assessing the accuracy of a 10ml graduated pipette‚ a 1ml blowout pipette and a Gilson P1000 automatic pipette. This

1.If the inclination angle is zero‚ how does the path of the Sun in the sky change as the planet moves from the right side of its orbit to the left? What is the longest duration (in hours) of sunlit time during the year? What is the shortest duration of sunlit time? How does the angle of sunlight striking the ground change? What is the change in average temperature? The path of the Sun in the sky doesn’t change as the planet moves from the right side of its orbit to the left. The longest

Cellular and Molecular Techniques - Lab #1 BIO 349 Lab Report #1 Microscopy and Staining Abstract The primary focus of this lab was on microscopy and simple stains. Microscopy that was used were magnification‚ slide preparation‚ and staining. Methylene blue‚ a simple staining component‚ was used to stain the slide in order to see the different microbes and determine their cellular shape. Introduction The purpose of this lab was to become familiar with the light microscope and how

Rousselle Molina Ms.Moraima Group 2; HW 1 9-25-12 EVOLUTION; NATURAL SELECTION I.ABSTRACT: As we all know‚ evolution is a change in population over a period of time. Natural Selection as its own mechanism takes place for survival of the offspring from varying changes of the environment. One good example of natural selection is the population of peppered moth predominant in England. During pre-industrial revolution‚ there were highly significant light colored moths that
