Stress Case Study

The Science of Stress is an informative video by National Geographic detailing the body response to stress. Stress is the body’s way of getting itself prepared to face a challenge. It is constant problem that everyone has to deal with. It was originally meant to aid our survival, but over time it has become dangerous and lethal to our well being. National Geographic’s video gives us a scientific view of what goes on in our bodies when experiencing stress and its effects on it.

The use of multiple test tubes and Parafilm was used for each experiment. Catechol, potato juice, pH 7 phosphate buffer, and stock potato extract 1:1 will be used to conduct the following experiments: temperature effect on enzyme activity, the effect of pH on enzyme action, the effect of enzyme concentration, and the effect of substrate concentration on enzyme activity. For the temperature effect on enzyme activity, three test tube were filled with three ml of pH 7 phosphate buffer and each test tube was labels 1.5 degrees Celsius, 20 °C, and 60 °C. The first test tube was placed in an ice-water bath, the second test tube was left at room temperature, and the third test tube was placed in approximately 60°C of warm water. After filling the test tubes with three ml of the

NaCl has been shown to have a negative effect on plant growth (Lee and Van Iersal 2016) and germination (Houle et al. 2001). The severity of these effects depends on the individual species’ ability to grow in saline soil (Atkins et al. 2009). WFPs are part of a group of plants called glycophytes, meaning that they have a limited ability to tolerate NaCl (Atkins et al. 2009). A study specific to WFP germination found a decrease in germination in WFPs

There are many different broad definitions of stress and how to cope with it, known as stress management.

The counselor worked with the client on assessing her situation and developing ways to help her friend without the added stress. The client appeared to struggle internally with making a decision to kick her friend out and he will possibly be living on the street or dealing with the added stress in supporting him. The client seems to believe he has no other support system other than her which is making her decision more difficult. The client was willing to entertain the idea of finding other support systems for him but the counselor is not sure if she will follow through because she appears to be enjoying his company even though this situation is placing a strain on her finances.

After the substrate solution was added, five drops of the enzyme were quickly placed in tubes 3, 4 and 5. There were no drops of enzyme added in tubes 1 and 2 and in tube 6 ten drops were added. Once the enzyme solution has been added the tubes were then left to incubate for ten minutes and after five drops of DNSA solution were added to tubes 1 to 6. The tubes were then placed in a hot block at 80-90oC for five minutes. They were then taken out after the five minute period and using a 5 ml pipette, 5 ml of distilled water were added to the 6 tubes and mixed by inversion. Once everything was complete the 6 tubes were then taken to the Milton Roy Company Spectronic 21 and the absorbance of each tube was tested.

The experiments involved PH buffers of different pH were added to potato juice, water, and the enzyme catecholase. The mixture was then subjected to spectrophotometer at a wavelength of 420nm taking the absorbance readings. In the second experiment, a phosphate buffer of PH 7.0 was used in different measures together with different measurement of potato juice and the enzyme catecholase then subjected to the spectrophotometer at a wavelength of 420nm. The data collected inform of table and analyzed using descriptive statistics such as line graph and later interpreted, showing that PH and enzyme concentration do affect the rate of enzyme reaction

In the following experiments we will measure precise amounts of potato extract as well as Phenylthiourea, combined with or without deionized water and in some instances change the temperature and observe and record the reaction. We will also investigate the different levels of prepared pH on varying samples of the potato extract and the Phenylthiourea and record the results. We will answer question such as what is the best temperature for optimum temperature reaction as well as the best pH level for the same reaction.

The significant difference observed in carbon flux rate between acutely exposed cold (5˚C) Hordeum vulgare (barley) and control (21˚C) barley supports our hypothesis, which states that when barley grown at a favorable temperature is acutely exposed to low temperature, the photosynthetic capacity will decrease. Similar results were observed in Garmash (2005) where barley was acutely exposed to 0˚C.

My life is fairly stress-free, which makes it difficult for me to give a good detailed example. However, like other students, school work is a main stressor. I tend to complete work the day it becomes available to me, I view it as a challenge, rather than a hindrance. So, my need to complete work right away; rather than relaxing and completing it over time is my main source of stress. I would consider this a challenge stressor since I start with an elevated level of stress, and relax later after completion. Once I am finished, I often experience positive emotions, from knowing I no longer need to worry. In conclusion, I would say I have pretty good control over my stress, which leads me to believe I do not poses the Type A behavior

Overall, the plant cells did not have an isotonic point higher than 4%. The difference in isotonic point between plant cells of different environment provides strong evidence for the hypothesis. The freshwater Elodea plant cells had an isotonic point of 1% while the saltwater Ulva plant cells had an isotonic point at about 4% supporting the idea that saltwater plants evolved to endure higher salt concentrations and have a higher isotonic point. Both the Onion cells and Fern Prothallia cells have isotonic points at 3% salt concentration suggesting that terrestrial plant cells have an isotonic point at about 3% salt concentration. Compared to sea water (salt concentration at 3%) the freshwater plants have lower solute concentration inside their cells, hence the plasmolysis of cells at lower salt concentrations, while saltwater plant cells have higher solute concentration, hence the plasmolysis of cells at higher salt concentrations. This evidence suggests that the plants evolving in environments with higher salt concentrations evolved to endure much higher salt concentrations from their

In this experiment we are going to describe stress and prove how can a prolonged exposition to it have a negative impact on memory. The definition of stress used in this experiment is: difficulty one suffers that causes worry, emotional tension or loss of concentration. The reason why this topic has been chosen is because stress is a part of nowadays, hectic society and it has a very noticeable effect on people’s performance, in either work or daily life. The outcome of this experiment could be used in several fields, such as education; to help reduce the amount of stress students deal with, so their grades could be improved. The results could also be used to enhance and boost employer’s

Stress is something that affects many people each and every day. Life is full of hassles, deadlines, frustrations, and demands. For some people stress is so common it is a way of life. Stress can be very harmful and or helpful. It could help motivate you to meet a deadline and perform a task under pressure. Stress can also be very harmful, such as memory problems, moodiness, aches and pains, and eating more or less.

At one time or another, most people experience stress. The term stress has been used to describe a variety of negative feelings and reactions that accompany threatening or challenging situations. However, not all stress reactions are negative. A certain amount of stress is actually necessary for survival. For example, birth is one of the most stressful experiences of life. The high level of hormones released during birth, which are also involved in the stress response, are believed to prepare the newborn infant for adaptation to the challenges of life outside the womb. These biological responses to stress make the newborn more alert promoting the bonding process and, by extension, the child's physical survival.

The patient is a 19-year old college student of Chinese descent who describes a history of personality issues after the death of his father at the age of 11 specifically with school studies. He experiences stress related to his father’s death which have had an effect on his behavior negatively with his family interactions primarily his mother. He finds his studies difficult, and is failing his coursework. He is a freshman in college, and is currently on academic probation. He desires to enter the pre-engineering program, but has failed coursework which he is taking over for this semester. He lives with his older brother who is the only other sibling, also a student in the pre-engineering program, and along with the client are the first American born family members. He does not have any other form of employment. The client has stated that his mother feels anxiety because of the pressure she feels about what others will think in the family about her son’s actions. The patient complains of headaches during studies, and has been told by a doctor that there is “nothing really wrong with him. He desires to become a Navy pilot, and needs to be entered into the pre-engineering program for this to occur. Along with the presenting problem there should be an inclusion of stress related to being a first generation American, and interactions with his mother.
