Temperature

To understand how homeostatic mechanism regulates the human body’s temperature, we must know and understand the organization of the human body and how it relates to homeostasis mechanism adapting to the external changes, such as the weather. It will be explained how the stimulus, receptors, integrator, effector, and the different tissue types play a key role in how the human body responds to changes in temperature. The human body is complex and consists of several levels of organization (Ireland…

experiment is to identify the unknown sample by calculating its specific heat capacity. 1. Introduction: Heat is a form of energy that is transferred between objects with different temperatures. The amount of heat released or gained by an object (q) depends on the mass of the object (m) and the change in temperature of the object (∆T). q = mCs∆T In this equation, the proportionality constant Cs is called the specific heat capacity and every…

8. Thermoregulation is keeping the body's temperature controlled or regulated. 9. The portion of the brain that contains sensors that monitor body temperature is the hypothalamus. 10. a) Two mechanisms the body uses to cool itself are the blood vessels dilating to radiate heat, and sweat glands increasing to increase sweat production. b) Two mechanisms the body uses to heat itself are the blood vessels constrict, reducing heat, and muscles beginning to shiver, generating heat. 11. a) The…

definitions to keep in mind. Thermal Niche is a development in which natural selection forms adaptation for an organism through temperature. Acclimation is the process for the organism to become accustomed to the climate change. Fitness is simply the survival of an organism, however, in the investigation, locomotion is more suited due to the focus on the affect temperature has on the organism’s performance. For this lab, the organism experimented on is a water flea, called Daphnia Magna. All of…

Electrical properties Figure. 8 shows the temperature dependence of resistivity of the Co(II), Ni(II) and Cu(II) complexes. As seen, the data reveal a semiconductor behavior where the resistivity decreases with the increases of temperature. The decrease of the electrical resistivity with increase of temperature is resulted from the increase of the charge carriers that can overcome the energy barrier and participate in the electrical conduction where in metal complexes, the metal…

well as the factors that affect this property. The objective of this experiment is to investigate the appearance and temperature of range of water that is lukewarm, scalding, simmering and boiling point. On top of that, we also need to determine the factors that boiling temperature of water alone and with various ingredients added. In this experiment, appearance and temperature range of water will be determined. Various amount of ingredient will be added and changed in boiling point will be…

Fish are cold-blooded aquatic vertebrates. They are highly susceptible to seasonal and diurnal variations in water temperature in their habitats. Any abnormal change in temperature may influence fish survival, change physiological, biochemical function and enzymatic activities. In order to address this, we exposed Bighead carp Aristichthys nobilis to an increase in temperature from 28°C to 38°C and measured the effects on histopathological changes in gill, liver and kidney tissues, physiological…

Introduction This experiment looks at the effects of pH, enzyme concentration, and temperature of the catalytic rate of different enzymes including alkaline phosphatase (ALP). Some of the enzymes used are involved in human digestion while others are involved in clinical tests for certain diseases (Wilson, D’Alessio, Schmitt Lavin, Keith, & BIOL 1500 Team, 2015). The ALP enzyme is used to diagnose diseases such as bone cancer, jaundice and cirrhosis of the liver. This enzyme also catalyzes the…

“The term pH is derived from a combination of “p” for the word power and “H” for the symbol of the element Hydrogen. Together the meaning is the power of hydrogen. pH used to compare the relative acidity or alkalinity of a solution at a given temperature. A pH of (7.00) describes a neutral solution because the activities of hydrogen and hydroxide ions are equal. When the pH is below (7.00), the solution is described as acidic because the activity of hydrogen ion is greater than that of hydroxide…

reaction is controlled kinetically and occurred because it had the smallest activation energy. Then after forming this compound, the reaction did not have enough energy to reverse and overcome that activation energy. After completion of the room temperature reaction, a white compound with a yellow tint was obtained. This indicates that the majority of the product was cyclohexanone semicarbazone,…
