In this condition the participant could enter into Hypothermia. Hypothermia is caused by exposure to low temperatures, the body starts losing heat more quickly than it can produce it resulting in the body temperature going down rapidly. The body can not replace the heat as it 's being lost to the environment, the severity depends on how low the body temperature drops. If the body drops below 35 degrees Celsius it is mild hypothermia, the body starts to shiver and vasoconstriction starts to reduce blood flow extremely.
Therefore this will be kept constant by creating the same mixtures, which will be used for all the trials. -Volume of solution inside cuvette will be kept constant for all trials by adding only 2.5cm3 of starch and iodine solution and 0.5cm3 of Amylase and Sodium-Chloride solution to the cuvette. -Conducting all trials for the experiment at room temperature 22ºC controls temperature. -pH is kept at a constant by using the same solutions of Starch-iodine and Amylase-Sodium chloride for all trials. Materials: •Digital weighing scale (0.001g uncertainty)
• Warming (vasoconstriction): when cold the body protects itself by moving blood from the extremities to the vital organs, ensuring that they are kept warm. With the blood diverted to the major organs the capillaries and pores narrow, the skin appears pale and heat loss is prevented. The erector pili muscles contract, causing body hair to stand on end, trapping air against the surface of the skin, which is then warmed by body heat. Shivering occurs, caused by rapid and repeated muscle contractions which work to raise body temperature.
1.5) judge by using some examples; write the importance of maintaining a constant internal environment in different condition at high temperature, low temperature, severe vomiting and too much fluid intake. Homeostasis is the procedure through which a life form keeps up certain interior conditions, for example, a human body 's inward systems keeping up body temperature at a particular level to anticipate over or under warming; this procedure is vital in light of the fact that it makes it workable for cells and organs to work legitimately. For instance, certain parts of the human body stop to work on the off chance that they turn out to be excessively hot or excessively frosty; this is the reason it is feasible for individuals to stop to death
For example, an experiment similar to this one could be how pressure could affect the time it takes for an Alka-Seltzer tablet to dissolve. Using A flask and rubber stoppers, you can compare the amount of time it takes for and Alka-Seltzer tablet to dissolve in regular room temperature water and room temperature water in a flak but with a rubber stopper stopping the air flow into the flask. This is related to the experiment performed above because the increase in pressure from the rubber stopper stopping the air flow in and out of the flask may affect the time it would take for the Alka-Seltzer tablet to dissolve. Another example of an experiment related to the one performed above is how the amount of water used to dissolve an Alka-Seltzer tablet effects the time it takes for one to dissolve. This also relates to the experiment performed above because it also affects how fast the rate of reaction is.
Most of the time, the choice of which method to use is a function of what individuals feel will provide the best results. If the affected body part does not experience an increase in temperature and the swelling is minimal, a person can continue to use heat therapy regularly to reduce the inflammation and pain in that part of the body. Patients who have rheumatoid arthritis or osteoarthritis are usually more predisposed to heat treatment as ice packs or cold create highly unfavorable sensations and may even worsen their symptoms. As for the cold treatment, it works best for areas where there is constant inflammation of the body part or bleeding.
Respiratory alkalosis occurs when a person is breathing to fast are deep and your CO2 levels will drop to low. When this happen, it will cause the blood to rise and become to alkaline. Treatment is chosen by the condition that may cause respiratory alkalosis. When the blood becomes too acidic this lead to respiratory acidosis. Respiratory alkalosis treatment or not bad unless the pH level is 7.5.
This is because if taken simple distillation into consideration. The column has a lower temperature at the top then the bottom thus there is a lower vapor pressure (Gilbert 126). And therefore the bottom as a higher temperature and in order to reach an equilibrium the temperature gradient is formed as shown the graph above (Gilbert 126).The column is utilized so that the vapor reaches the condenser at the bottom of the column and therefore several simple distillation trials need to be done in order to ensure that the distillation can be very effective (Gilbert 126). Boiling point and vaporization are inversely proportional, so lower boiling point means faster vaporization so in this case acetone moves down the column faster leaving the 1-propanol for the last fraction (Gilbert 126). That being said, in the fractional distillation, the rings act as the trials in the simple distillation (Gilbert 126).

Negative feedback is a regulatory mechanism where a stimulus causes an opposite output and I does this to maintain the ideal level of what is being regulated ad example of negative feedback in the human body is temperature regulation as when the body’s temperature is high it is detected by nerve cells which send this information to the part of the brain which regulates body temperature called the thermoregulatory centre and the brain sends out signals to cool the person down by making them sweat. Positive feedback does the opposite to negative feedback instead of causing an opposite output it aids a physiological process and amplifies the action of that system, an example of positive feedback in the body is when the skin is cut and a blood vessel has been damaged, so platelets in the blood stream come to the site of damage and begin releasing chemicals which trigger more platelets which then triggers even more platelets and this carries on until the
The low body temperature from the cooling pads causes the immune system to slow down. Typically, a strong immune system is extremely crucial to the body’s overall health from exterior infections and diseases; however, during the process of induced hypothermia, a decrease in immune system is prefered because it reduces the risk of inflammatory reactions. In a healthy body, inflammatory reactions are important because they will create an increase in blood circulation, which will normally help fight off
There are several hypotheses should be required to test with decreasing central nervous system drive. Muscle inosine monophosphate concentrations temperature on metabolism - and reflects the induced effect. This was to reduce the dependence on thermal storage of glycogen in the muscles as the body based on lower lactate levels. 3.
Another reason as to why I suggest this is because tap water may have other substances or little things mixed, which may cause an inaccurate reading of the mass which will cause an error in density, so it is better to use pure water. Finally, temperature may play a big role in this as well. The accepted room temperature would the density of 1g/mL is 21°C. If the room temperature is measured, then it can be considered that there will be a change in density due to an increase or decrease in the average room
Background Information In this lab KCl, NaCl, and a mixture of MgCl2 and NaCl are the independent variables that all lower the freezing point of water. Ice is used as the controlled variable because it is what the salts are lowering the freezing point of. Salt (Na) weakens intermolecular forces of water, thus lowering the the freezing point. This is why in colder climates where icy roads and walkways are a liability, salt is often scattered over areas that are slick with frozen water.
