I am going to investigate how the resistance of the wire affects a current flowing through a wire. I know that as resistance changes‚ current changes‚ as Ohm’s law: I = V/R. If one part of an equation changes‚ the equal must be done to the opposite side. To detect how resistance affects current‚ I must first discover what factors affect resistance. These factors are: · Length of the wire if a wire is longer; there are more particles for electrons to move through‚ and therefore more resistance

uses UV filtration and eliminates 100% bacteria and virus. Thus‚ water produced using the water dispensing machine does not contain any harmful chemicals and other matters and can be consumed directly without boiling as it can filter up to 0.0001 micrometer of dirty and dangerous matters thus producing safe and clean drinking water.

sarcomere to myofilaments. (b) Explain the sliding filament model of contraction using appropriately labeled diagrams of a relaxed and contracted sarcomere. (a.) The region of a myofibril between two successive Z discs is a sarcomere. It averages 2 micrometers long and is the smallest contractile unit of a muscle fiber. It contains an A band flanked by half an I band at each end. Within each myofibril‚ the sarcomeres align end to end like boxcars in a train. (b) In a relaxed muscle fiber‚ the thin and

It is thought that archaea and bacteria were diverged early in their existence because of all the dissimilarities between the two groups. Both bacteria and archaea are enclosed in cell membranes. Archaea have a single cell membrane that absences a peptidoglycan wall and also their genetic transcription and translation‚ the two main processes in molecular biology do not show the typical bacterial features‚ but are quite similar to those of eukaryotes. Archaea are more related to eukaryotes‚ even though

Through this experiment‚ Egeria densa was observed using a microscope. The task was to observe and identify the different types of cell‚ cytoplasmic streaming‚ and plasmolysis of Egeria densa. First‚ the microscope was examined and investigated to master the use of the equipment. A microscope slide grid which was on the slide glass was required to be seen clearly using 4x‚ 10x and 30x. During the latter part of the experiment‚ the Egeria densa was observed using the microscope to understand the

Introduction of Ceramics What is Ceramics? A ceramic is an inorganic‚ non-metallic solid prepared by the action of heat and subsequent cooling. Ceramic materials may have a crystalline or partly crystalline structure‚ or may be amorphous (e.g.‚ a glass). Because most common ceramics are crystalline‚ the definition of ceramic is often restricted to inorganic crystalline materials‚ as opposed to the non-crystalline glasses. The word ceramic comes from the Greek word "κεραμικός" (keramikos)‚

Intravenous (IV) study day Guided independent Study In preparation for administering IV medication when you have registered as a nurse‚ it is important that you have some theoretical understanding of related issues. Completion of this guided independent study workbook will enable you to review some topic areas related to IV therapy. Once this is completed‚ you will be able to observe IV therapy in your practice placements and you will be able to take part in drawing up IV medication. NB Student

Foliar and Root Anatomy of Evergreen Tree‚ Citrus Limon (Rutaceae) Abstract: Foliar and root anatomy were obtained from a Citrus Limon to be studied upon and the main focus were the stem‚ petiole‚ leaf and root. Plant material was obtained from Manila Seeding Bank Foundation Inc. and was brought to Ateneo De Manila University. Sections were subjected to staining and dehydration‚ after which they were viewed under a light microscope and measured using a light microscope. The young stem has a periderm

Bill Bryson‚ Notes from a Small Island‚ Black Swan‚ 1995 In the morning I awoke to find rain falling over the hills in great blown sheets. I breakfasted‚ settled the bill and spent a protracted period struggling into waterproofs in the front hallway. It’s a funny thing. I dress myself most days without incident‚ but give me a pair of waterproof trousers to put on and it’s as if I’ve never stood unaided. I spent twenty minutes crashing into walls and furniture‚ falling into pot plants and‚ in one
