TUTORIAL 2
NERVOUS SYSTEM I

Student’s Guide:
At university level, the tutor facilitates student learning without spoon-feeding. Therefore, you are expected to:

* Read your textbook, attempt the questions before the tutorial * You may enter the class and sign your attendance after showing your tutor that all tutorial questions have been completed; even if you don’t know how to do, write something - you’re not advised to leave answers blank in the finals. * Write answers on board if you wish to receive tutor feedback
(no answer, no feedback) * Be independent: consult textbooks or dictionaries on your own first before asking the tutor * All questions are compulsory. 1 mark may reflect 1 answer point.
(No half mark is awarded in the finals marks)

Same Room Booking – Female and Male Date | 23 - 26 June 2014 (Monday to Thursday) | Time | 8.30 am to 5.30 pm | Venue | Accommodation Office – (ACO) - Einstein Ground Floor | Residents are required to come to ACO to secure their rooms for the following semester during the Advance Room Booking period. Invoice collection will be from 30 June 2014 onwards at ACO. If you fail to do so during this time period your room will not be available for the following semester. If your roommate is graduating and or leaving the Halls of Residence you will need to find a new roommate. Please update ACO as soon as possible with the new roommate’s name. If you are unable to find a new roommate you will be required to fully check out from the room and ACO will reassign you to another room. When a room is totally empty the university is able to conduct preventive maintenance. There is storage space available. Boxes will be provided by ACO and you will need to return them 3 days after you check in. 2. Changing Room Policy Residents who wish to change rooms will only be considered on a ‘Case by Case Basis’ and ‘Subject to Room Availability’. Residents need to book back their same room during the Advance Room Booking period and to drop by ACO to complete an Appeal Form and submit it with a supporting letter from 1 - 2 July 2014.

...nothing more than a device built for doing various computations quickly, using logarithms. See Eli Maor’s e: The Story of a Number for more on this. Today, logs are no longer used in routine number crunching. But there are still good reasons for studying them. Why do we use logarithms, anyway? • To find the number of payments on a loan or the time to reach an investment goal • To model many natural processes, particularly in living systems. We perceive loudness of sound as the logarithm of the actual sound intensity, and dB (decibels) are a logarithmic scale. We also perceive brightness of light as the logarithm of the actual light energy, and star magnitudes are measured on a logarithmic scale. • To measure the pH or acidity of a chemical solution. The pH is the negative logarithm of the concentration of free hydrogen ions. • To measure earthquake intensity on the Richter scale. • To analyze exponential processes. Because the log function is the inverse of the exponential function, we often analyze an exponential curve by means of logarithms. Plotting a set of measured points on “log-log” or “semi-log” paper can reveal such relationships easily. Applications include cooling of a dead body, growth of bacteria, and decay of a radioactive isotopes. The spread of an epidemic in a population often follows a modified logarithmic curve called a “logistic”. • To solve some forms of area problems in calculus. (The area under the curve 1/x, between x=1 and x=A, equals ln A.) ...

Apparatus and materials: Ramp, wooden block, pendulum bob, plumb line, steel ball, wooden board, carbon paper, meter ruler, plasticine. Setup: 1. A ramp was set up at the edge of a bench. 2. A plum-line is suspended from the edge of the bench. 3. A wooden board is mounted horizontally using two clamps so that the board is situated about the bottom of the ramp. 4. A sheet of blank paper is placed on top of the board. 5. A piece of carbon paper is placed on the top of the blank paper. The ink-side of the carbon paper is facing down. 6.

PART 6 Rules & Regulations Teams are usually consisting of six players or more. Each team selects one team member to be the "goal catcher" and two others as shooters. The rest are fielders. Fielders may take position they like outside of the platform on their half of the pitch. The 'goal catcher' goes over to the other half of the pitch and stands in the goal platform. Goals are scored if the goal catcher catches a ball thrown by the shooters. Por Wee Chiat, Claudia Ng and Emily Tye are the referees of the matches that will be held.

The strength of the force holding oppositely charged particles together in any material is described by Coulomb’s Law (equation 8.1). According to this law, force of attraction or repulsion between two charged species is directly proportional to the magnitude of the charge on the particles (qA and qB in equation 8.1) and inversely proportional to the square of the distance between the two particles (r in equation 8.1).

...enzymes in human cells. Above this temperature the enzyme structure begins to break down (denature) since at higher temperatures intra- and intermolecular bonds are broken as the enzyme molecules gain even more kinetic energy.Also Enzymes have an active site. This is part of the molecule that has just the right shape and functional groups to bind to one of the reacting molecules. The reacting molecule that binds to the enzyme is called the substrate.At high temperature,the active site is said to be denatured.Therefore,the active site cannot bind with any subtrate anymore.Amylase breaking down the starch suspension into maltose and maltose into glucose when HCL was added into solution B .This is because solution B was hydrolyzed and the H+ ions present break down the bond in between molecules of the solution B The HCl will denature (unfold) the amylase (as noted at the bottom of the link you provided), disrupting the shape of its active site, therefore it won't work anymore.
