Lab 4: Endocrine System Physiology | 1. | | Refer to Activity 1: Determining Baseline Metabolic Rates. How did the baseline metabolic rates of the three rats differ? Answer: | The metabolic rates for the thyroidectomized and hypophysectomized rats were lower than that of the normal rat. | | | 2. | | Why did the metabolic rates differ? Check all that apply: Answers: | The hypophysectomized rat lacked thyroid-stimulating hormone. The thyroidectomized rat lacked thyroxine hormone.

Date report submitted: June 18‚ 2015 Title: Lab Techniques and Measurements PURPOSE: The purpose of this experiment is for the students to get a better knowledge with the laboratory tools and techniques. This experiment taught me how to convert between SI units and standard American units of mass‚ length‚ temperature‚ volume and time as well as how to measure the units. Students become proficient in laboratory techniques such as measuring temperature and volume and calculating within them. Procedure:

ACIDS AND BASES The reason that acid-base reactions are so important is that many of the things you come into contact with on a daily basis are either acids or bases. Most fruits are acids‚ as are carbonated beverages‚ tea‚ and battery acid. Common household bases include baking soda‚ ammonia‚ soap‚ and antacids. What are acids and bases? There are not one but three common definitions used to describe acids and bases: 1. Arrhenius acids and bases 2. Brønsted-Lowry acids and bases 3. Lewis acids

BCS 145 LAB: AXIAL SKELETON WHY ARE WE DOING THIS LAB? The skeletal framework of the body is composed of at least 206 bones and the associated tendons‚ ligaments‚ and cartilages. The skeletal system has a variety of important functions‚ including‚ the support of soft tissues‚ blood cell production‚ mineral/electrolyte and lipid storage‚ and‚ through its relationships with the muscular system‚ the support and movement of the body as a whole. Skeletal system disorders can thus affect many other
