EXPERIMENT 5 Title: Conductivity of Strong Electrolytes Date: 16 August 2005 Objectives: ▪ To determine the relationship between the concentration and conductivity of various electrolytes ▪ To determine the conductivity at infinite dilution ▪ To determine the activity coefficients Theory: The resistance‚ R of a conductor with a similar cross section is proportional to the length (l) and inverse to the cross section area(A)‚ therefore; [pic]

Severe stress‚ such as the death of a loved one‚ divorce‚ or job

Two of humanity’s main priorities are at stake: protecting life and curing disease. Embryonic stem cells are the solution to the many unanswered questions surrounding these priorities. Many people question why scientists cannot simply use adult stem cells for their research instead of using embryonic stem cells. Adult stem cells have been researched for a much longer period of time and some treatments have successfully been developed from them. There are a couple of major constraints on the

to another individual’s internal state has provided great motivation for research. One source of explanation arose from research on mirror neurons-which fire both during execution and observation of a behaviour (Rizzollati & Arbib‚ 1998). This particular class of neurons plays a crucial function in human social interactions. The importance of the mirror neuron system (MNS) for communication can be understood through its influence on nonverbal communication including facial expressions and hand gestures

subject of mirror neurons‚ which are neurons that fire when an animal acts or observes the same action done by another. We learned that these neurons exist primarily in the ventral premotor cortex F5 areas of a monkey’s brain. Experiments proved that neurons in the VPC F5 area fire when a monkey does an action‚ but also fire when a monkey watches a human do the same action. However‚ when the monkey watches the human just carry out the motions of the action‚ not actually do it‚ the neurons in this area

Scenario You are a ‘gifted and talented’ athlete who is taking part in some training and your coach has insisted that you understand more about HOW your body works during exercise to maximise your training and ultimately your performance. You will participate in some practical activities and look at readings to interpret what the body systems do in response to becoming active. How we physiologically change from being at rest to being active. Criteria reference To achieve the criteria

the physiological methods of perception. The senses and their operation‚ classification‚ and theory are overlapping topics studied by a variety of fields. Sense is a faculty by which outside stimuli are perceived. What are Senses? We experience reality through our senses. A sense is a faculty by which outside stimuli are perceived. Many neurologists disagree about how many senses there actually are due to a broad interpretation of the definition of a sense. Our senses are split into two different

Conductivity Solutions Abstract: We produced conductivity tests in water and other various solutions with a computer faced Conductivity Probe using the unit of microsiemens per centimeter (uS/cm) to find out which solutions had a high conductivity and which solutions had a low conductivity. Many different solutions vary in conductivity due to the ratio of ions. Different levels of ions have an impact on conductivity because of the different charges and different types of bonds. Conductivity is
