Gram Stain: The important part of this experiment is being able to determine a bacterium based on its cell wall structure. It also helps indentify if the unknown organism is a Gram positive or Gram negative. This is the initial step that must be taken before any other lab procedure may continue on to ensure the purity is present‚ the arrangement of the cells‚ and the shape the cell has. The staining of the cell starts off with using the primary stain‚ Crystal Violet which is a purple color‚ to begin

ECONOMIC GROWTH AND ECONOMIC DEVELOPMENT In contemporary times‚ certain economic registers are used frequently. Arguably two of these most used terms in economics‚ ‘economic growth’ and ‘economic development’ are terms that just about everyone is at least remotely familiar with‚ even if they have not studied economics at all. Sometimes it seems everyone knows what economic growth and economic development is. Politicians use these terms all the time‚ and so do teachers‚ managers and even preachers

Experiment 5 Polytropic Expansion of Air Object The object of this experiment is to find the relation between pressure and volume for the expansion of air in a pressure vessel – this expansion is a thermodynamic process. Introduction The expansion or compression of a gas can be described by the polytropic relation ‚ where p is pressure‚ v is specific volume‚ c is a constant and the exponent n depends on the thermodynamic process. In our experiment compressed air in a steel

Can classical and operant conditioning account for the development of phobias? Classical conditioning involves pairing an unconditioned stimulus with a conditioned stimulus. The conditioned stimulus then produces a conditioned response. Operant conditioning then refers to associations between the response and the outcome. The following essay will examine evidence supporting classical and operant conditioning as a cause of phobias. Other theories‚ such as biological and evolutionary‚ will also

Phobias and Addictions as Related to Classical and Operant Conditioning Learning can take place through a variety of methods; two of these methods are classical and operant. Classical and operant conditioning can contribute to a student’s success or failure; in addition‚ phobias and addictions can develop. “Learning is any enduring change in the way an organism responds based on its experience.” (Kowalski & Westen‚ 2011‚ p. 164). Classical conditioning has been shown to aid in the development

October 2012 Applying Operant Conditioning To Ones life Operant Conditioning can easily be applied to our everyday lives. “It is a type of learning in which behavior is strengthened if followed by a reinforcer or diminished if followed by a punisher.” (Myers 236) When we observe our environment and the people with-in it‚ we will be able to understand and comprehend actions duly. We are also able to discern the consequences of our actions. An everyday situation which operant conditioning can be

Aim To investigate how parachutes work and whether size matters to performance. Background According to Agee (2010)‚ “As a skydiver is falling‚ the force of gravity is pulling them towards the earth… The parachute slows the skydiver down because it causes air resistance or drag. The air pushes the parachute back up‚ and creates a force opposite to the force of gravity‚ slowing the skydiver down.” Question We wanted to find out how the size of a parachute would affect its descent as we felt slowing
