Karolina Tanskanen Product: Hotel Accommodation Market Segment: Russian Tourist The following problem was to develop a market profile and how to increase the number of Russian tourists in hotels. The study focuses on dealing with Russian tourists from the tourism perspective. This information can be used to find out better ways to serve Russian tourists and make them interested in services provided in Australia. The study reveals that in Australia we have a lot of potential for cultural‚ historical

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

Review Sheet Exercise 3 Neurophysiology of Nerve Impulses Eliciting (Generating) a Nerve Impulse 1. Why don’t the terms depolarization and action potential mean the same thing? They require different things. Action potential requires depolarization and repolarization. Depolarization doesn’t require anything. 2. What was the threshold voltage in Activity 1? 3.0V 3. What was the effect of increasing the voltage? How does this change correlate to changes in the nerve? The action potential

Physiology Exercise 3 Activity 1 1. Explain why increasing extracellular K+ reduces the net diffusion of K+ out of the neuron through the K+ leak channels. Your answer: By increasing the extrecellular K+ the net diffiusion of K+ out the neuron through the eak channels is reduced. This is caused by the flow of ions following the concentration gradient of traveling from an area of high concentration to areas of low concentration. The higher concentration gradient would result in a reduced diffusions

Aerobic exercise has many outcomes of an individual performing in activities that increases their intensity for a certain amount of time. A common outcome people assume initially is the ability of losing weight. Along with that‚ it helps them develop more muscles in the body. Aerobic exercise has many more physical benefits of doing it on a regular basis. At the same time‚ it effects state anxiety as well. State anxiety is defined as the temporary experience of emotional arousal when encountering
