Investigating the water potential of a potato Aim Osmosis is the movement of water molecules from a region of high water concentration to a low water concentration through a semi-permeable membrane. Our aim is to investigate the water potential of a potato through osmosis‚ by finding the difference in weight before and after the potato has been set in a solution of water‚ sugar or salt. Trial Method Firstly we collected the equipment. This included a scalpel‚ potato cutter‚ and test tubes. Then

Integrated working involves the collaboration of various key personnel and stakeholders in the process. The key personnel are: Those that educate –‚ the class teachers‚ subject teachers‚ special education needs teachers and support workers‚ the professionals who advise the key personnel and assist in resolving issues – the school director‚ head teachers‚ section heads‚ special education needs co-ordinator (SENCO). SENCOs work very closely with the head teacher and governing body in determining

What are the roles and responsibilities of the special educator in the collaboration process? What are they for the general educator? What potential conflicts may arise between the two roles? The special educator is responsible to see that an appropriate plan of learning (also called IEP ) is developed for each student requiring special education. A special educator is responsible for seeing that a student is allowed access to the general curriculum‚ yet at the same time‚ have a learning plan

The Action Potential An action potential‚ also called a spike‚ nerve impulse‚ and discharge‚ is the rapid reversal of charge of the cell membrane. These changes in charge occur within milliseconds‚ meaning the action potential travels very quickly down the axon in order to convey information over long distances. This transfer of information occurs within six phases and requires the presence of multiple pumps and channels embedded in the membrane to control ion concentration. Phase 1: The Resting

In this assignment‚ I have the opportunity to thoughtful answer fives questions. It is indicated that there is potential child welfare issues that are present through reading Callie’s story and Brain’s story. Therefore‚ it is indicated that the first one is that there is potential neglect because from the case study it states that Callie and the children sleep in the unfinished basement. It is indicated that neglect can be defined as any serious act by a person having the care of a child that‚ within

Potential and Kinetic Energy Transformations Potential and kinetic energy can be found in things all around us‚ especially in roller coasters. Potential energy is stored energy in an object‚ and kinetic energy is energy of motion or speed. On a rollercoaster it can switch from potential to kinetic energy very often. The rollercoaster starts off with a chain and motor and exerts a force on the rollercoaster which pushes the ride to the top of the hill. Throughout the process of going up the hill

carries important information through action potential‚ this is significant activity of the neurons to allow us to understand abnormality in the nerve that cause disorders. The objective of this study was to trigger a compound nerve action potentials (CAPs) and examine the effects of a stimulus voltage on a nerve and inspect their threshold‚ refractory period and also their velocity. Compound nerve action potentials (CAPs) are summed action potential of one nerve‚ one nerve consists of many neurons
