1) Make a graph of resting heart rates from Activity 1. Provide a physiological explanation for fluctuations in resting heart rate over time. Discuss a couple of extrinsic factors that influence the autonomic nervous regulation of resting heart rate. The resting heart rate fluctuates over time because it is under control of the autonomic nervous system and the fluctuations are a result of the sympathetic and parasympathetic systems trying to balance each other out. There are many reasons

Hormones and Metabolism Activity 1: Determining the Baseline Metabolic Rates 1. Which rat had the fastest baseline metabolic rate? Normal rate 2. Why did the metabolic rates differ? Because of the different organs that were removed from the two other rats that would produce certain hormones 3. If an animal has been thyroidectomized‚ what hormone(s) would be missing from its blood? thyroxine 4. As a result of the missing hormone(s)‚ what would the overall effect on the body and metabolism

Equipment Calibration is defined as the act of adjusting and evaluating the precision and accuracy of measured equipment. It allows the user to get an accurate and precise reading of measurements to its actual true value. However‚ in order for the experiment to be effective is must consist of validity‚ reliability‚ and objectivity. Validity is defined as the ability of a test to measure what it claims to measure. Reliability is the consistency of test results and objectivity is defined as a test

What are the consequences of the removal/extinction of an organism from the food web? The extinction or removal of an organism from a food web can affect different organisms directly or indirectly‚ depending on the trophic level the organism is and in what role they play in the food web‚ if it is carnivore‚ herbivore‚ omnivore‚ etc. Extinction has also been important for evolution in food webs. Some food webs are generated from the reaction with repeated extinctions‚ and the extinction rate is
