The Infant brain begins to develop a few weeks after conception‚ and most of the definable structures begin to develop at about eight weeks after conception. The first synapses occur seven weeks into the pregnancy within the spinal cord. Synapses occurs when neurons pass signals between each other to relay and receive information. A neuron consists of a cell body‚ multiple dendrites‚ and an axon. The cell body serves as the command center for the neuron‚ it contains DNA (deoxyribonucleic acid) and

After obtaining experimental values of ∆Hrxn‚ explain any discrepancy of the values to the theoretical. Give some possible sources of errors. - There are many potential errors in doing the calorimeter experiment. The set up may not be a perfect insulator. There may be a leak of heat inside the reaction since the students opened the test tube while adding the HCl‚ or there is a hole in the styrofoam where heat can escape. This will result to lower ∆H reading. Also‚ there might be an error in preparing

Ben Franklin Benjamin Franklin was born on January 17‚ 1706‚ in Boston in the Massachusetts Bay Colony. His father‚ Josiah Franklin‚ a soap and candle maker had 17 children. Benjamin was his very last child. Ben was removed at 10 from the Boston Latin School to work with his father at candle making‚ but dipping wax and cutting wicks didn’t spark with him. Later on‚ Josiah apprenticed Ben at 12 to his brother James at his print shop. Ben loved it‚ despite his brother’s hard treatment. When James

The electrophorus consists of a dielectric plate; it is an electrical insulator and a metal plate with an insulating handle. It works by the dielectric plate being charged through the triboelectric effect by rubbing it with fur or cloth. The dielectric gains create negative charge by rubbing together.

A force can do one of four things to an object: 1. Make it speed up - accelerate. 2. Make it slow down - decelerate. 3. Change its direction. 4. Change its shape. If something is doing one of these four things there must be net force acting upon it. Newton’s First Law ’Every body continues in a state of rest or uniform motion unless acted upon by an external force.’ Something without net force acting on it will either stay still or move at a constant speed in a straight line until

Properties of Water Water is essential for life as we know it on earth. It is used by plants and animals for basic biological processes which would be impossible without the use of water. The origin of all life can be traced back to the water in the Earth’s precambrien seas. Water is also the universal solvent. It reacts with more elements and compounds than any other substance known to man. Water is a polar molecule made up of on atom of hydrogen and two atoms of oxygen. It is attracted

Circuit boards are about a dollar apiece‚ and are simply a layer of copper over an insulator. The typical size is usually 3.5 inches by 5 inches. Drawing is simple; all that is required is an indelible marker‚ such as a Sharpie. A ruler is also helpful. #Draw out your circuit on your board with the Sharpie. Keep in mind that copper cannot
