a black body experiment in order to experimentally confirm the Stefan-Boltzmann constant. A black body is an object which allows all entering radiation‚ without reflection‚ to enter the object‚ absorbs all of the radiation‚ and subsequently releases radiation based on its own constant temperature. Another key factor is this absorption happens at all various wavelengths and all angles [1]. The term “black body” or sometimes referred to as a “black surface” was coined because it is a body which visually

learning any information is simply to repeat it by rote. Typically this will include reading over notes or a textbook‚ and re-writing notes. Methods based on communication skills e.g. reading and listening[edit] The weakness with rote learning is that it implies a passive reading or listening style. Educators such as John Dewey have argued that students need to learn critical thinking - questioning and weighing up evidence as they learn. This can be done during lectures or when reading books.

Aim: To investigate how effect of Detergent Concentration (cont.) has on Membrane permeability of Beetroot cells. Hypothesis: I predict that as detergent concentration increases‚ the solution will become less clear‚ plus mass increases. The increases in mass will indicate that the water potential of the Beetroot cell is lower than that of the surrounding sucrose solution. The Beetroot discs will become flaccid and decrease in mass if the water potential of the surrounding solution is lower than

Describe how the body responds to stress (6 marks) Acute stress causes the arousal of the autonomic nervous system (ANS). The ANS comprises of the sympathetic nervous system (SNS) which prepares the individual for ‘fight or flight’ and the parasympathetic branch‚ which returns the individual to their original state of relaxation. Part of the SNS response is the sympathetic adrenal system (SAM)‚ this system along with the SNS is collectively called the sympathomedullary pathway. The SNS is activated

When the doctor said‚ I’m sure you have a little lady in there‚ Joy’s parents told all their relatives and friends that their baby was

How does Glucoregulation work? - Glucagon When blood glucose levels fall below 5mM‚ the alpha pancreatic cells detect this change and release the hormone glucagon. When glucagon bonds to the glucagon receptors that are found mainly in the liver‚ it stimulates a response within the organ that causes glycogen to be converted into glucose. For this reason‚ the liver is said to act as the effector in this system. Glycogen is the branched polymer storage molecule of glucose that is stored in the liver

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 use of adult stem cells. They have proven to be very difficult to work with‚ one of the

There are many different types of viruses that are out in the world that we have discovered. Many range from slightly harmful to fatal. Also‚ there are many viruses that affect certain type of organisms. One of many different viruses that can affect different organisms is the virus called rabies. Since Rabies is spread through a virus‚ we will discuss how viruses work. With the many different types of viruses‚ there are different ways that viruses affect the body.
