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

Exercise 1: Dissolved oxygen is oxygen that is trapped in a fluid‚ such as water. Since virtually every living organism requires oxygen to survive‚ it is a necessary component of water systems such as streams‚ lakes and rivers in order to support aquatic life. The dissolved oxygen is measure in units of ppm—or parts per million. Examine the data in Table 2 showing the amount of dissolved oxygen present and the number of fish observed in the body of water the sample was taken from; finally‚ answer

Lab 1 – Ubiquity of Microbes Bacteria are the most widely distributed organisms in the biosphere. They are found in all different types of soil‚ water and even in the bodies of other living organisms. Every single place that humans have explored on the Earth‚ have shown to contain microbes. Bacteria are living organisms and like all living organisms‚ they require energy and carbon sources in order to metabolize and reproduce. And like all living organisms they respond to changes in their environment

An enzyme is a protein catalyst reaction by lowering the activation energy required for that reaction. The enzyme is unaltered at the completion of the reaction. In this stimulation the amount of product produced during the course of an enzymatic product produced during the course of an enzymatic reaction will be measured. Hypothesis 1: What is the estimate optimal of ph? Hypothesis 2: What is the estimate optimal of temperature? Hypothesis 3: How does the concentration of enzyme influence the rate of reaction? Why do you think this occurs

animals grow faster. For the solution they introduced the use of hormones. These hormones include estradiol‚ progesterone‚ testosterone‚ zeranol‚ trenbolone acetate and melengesterol acestate. Some of these hormones are found naturally in humans and some are synthetic growth promoters. But‚ is it safe for these foods to be consumed by people; and do they have any effects on our bodies? First‚ let’s define the term hormone. Hormones are chemicals that are produced naturally by our bodies and in the

BALANCE LAB Introduction The purpose of this lab is to become familiar with how to use the ChemLab program for determining mass using both the centigram balance and the electronic balance. Using the centigram balance‚ the mass‚ in grams‚ of a copper slug will be determined by both direct weighing and weighing by difference techniques. Using an electronic balance‚ the wight of a copper slug will be determined by also utilizing direct weighing and weighing by difference. Average mass of a
