Response rate

effect the rates of most biological reactions and biological processes in ectotherms. The rates of ontogenetic growth and development are no exceptions. Ectothermic animals develop faster at warmer temperatures and they usually mature at smaller body sizes. This phenomenon has been called the temperature size rule (Zuo et Al. 2011). The temperature size rule is a necessary outcome of differences in the temperature dependence of somatic growth rate and development rate, thus proving rates of…

35°C, 40°C), three different Daphnia Magna’s (per group), a dropper, a net, a timer, a microscope tray and a microscope. First, our group gathered our focal temperature water at 40°C and a Daphnia Magna as the equipment was set to collect its heart rate. We then placed the organism outside room temperature water into the 40°C water and allowed it acclimate for an interval of 30 seconds. When the time was met, we used the dropper to place the Daphnia Magna onto microscope tray with the net…

STRESS AND COPING STRATEGIES Module I: Stress Stress can be defined as actions and circumstances to which you cannot respond adequately or to which you respond at the cost of excessive wear and tear on the body. Stress is an emotional and physical reaction to change. Stress is defined as “The adverse reaction people have to excessive pressure or other types of demand placed on them” Stress can act as a creative force that increases drive and energy, but once it reaches a certain degree, the…

When it comes to insurance companies their main goal is correlate rates for policies as closely as possible with the actual cost of claims. The reason for this is because if the rate will be too high clients will move to other providers causing the company to lose market insurance or they will set the rates too low and cause them to lose money. So one tool that insurance companies use is credit scoring. The reason for this is because studies have shown that how a person manages their financial…

care for hospitals and healthcare organizations, it is accredited by the American Nurses Credentialing Center or the ANCC (ANCC, 2008). Many research data indicate that there are lowered percentages of patient mortality deaths, higher nurse retention rates, and more patient’s satisfaction in Magnet hospitals versus non-Magnet hospitals. As of 2015, only 426 or approximately 8% of healthcare organizations out of nearly 5,000 healthcare organizations in the United States received Magnet…

progression of the capital. Capital market theory is used to measure the returns wanted by investors and the intrinsic risks involved; it is model that is used to price assets and most commonly used is to price shares. It is most definitely important response to financial judgment making. Besides that, Capital market theory develops a model for all unsafe assets and ads on the portfolio theory. For the development of capital market theory, the concept of risk free asset is most crucial. Hence,…

Anxiety is our body's normal reaction to a stressful situation and can induce an increase in heart rate and breathing, a change in blood flow causing dizziness, sweating and nausea. A 'perceived threat' can trigger our 'fight or flight' response. It helps us prepare for situations such as public speaking, interviews or participation in sports. Generally, once the cause passes the stress will pass. However for some, it may not, and anxiety will occur without any discernible trigger. Repeated…

genres have a different affect on people’s heart rate. After watching the sing-along movie, High School Musical 2, most of the people’s heart rate decreased. The movie caused 11 out of the 17 people tested to decrease. It had an average and mean of 70.4 bpm before and 67.6 bpm after. The sing-along movie had the smallest standard deviation. There was a standard deviation of 7.98 before and 9.44 after. Most of the people being tested had a heart rate similar to the mean and each other. After…

catalyzes. However, in order for a chemical reaction to move forward, an energy barrier must be, which is precisely where enzymes are crucial. Enzymes bind to substrates, lowering the energy barrier so that the chemical reaction occurs at a faster rate. Catalase, a common enzyme that is found in almost all living organisms who are…

Heart Rates in Organisms. Jesutofunmi Bankole El Centro College Abstract This experiment studies the effect of caffeine and alcohol on heart rate. This lab experiment detailed how water flea, (Daphnia magna) a transparent aquatic organism whose heart can be easily identified using a compound light microscope, was used to study the effects of caffeine and alcohol on heart rates. According to the research alcohol was observed to have caused a decrease in the heart rate of…
