Thermometer 1 roll of insulation tape Procedure 1. Wind the wire around the PVC pipe. Fix the ends of the wires to the insulation tape. Remove about 3 cm. of insulation from the wire using the tips of the paper knife. Measure the resistance of the wire using the ohm setting on the multimeter. 2. Connect the batteries in series using the jumper wires to produce 4.5 V. The ammeter‚ battery and wire wound around the pipe should be connected as shown in figure 1. 3. Record

[Type text] [Type text] [Type text] _An experiment on the effect of surface area to volume ratio on the rate of osmosis of Solanum tuberosum L._ BACKGROUND A cell needs to perform diffusion in order to survive. Substances‚ including water‚ ions‚ and molecules that are required for cellular activities‚ can enter and leave cells by a passive process such as diffusion. Diffusion is random movement of molecules in a net direction from a region of higher concentration to a region of lower concentration

Asthma Asthma is a respiratory disease. Asthma has a high reactivity of the bronchial tubes to various stimuli and that reaction blocks air flow by narrowing and obstructing the trachea and lungs. (Woollbert‚ Robert‚ 1996) This causes difficulty breathing‚ and while it’s normally temporary and reversible it can still be life threatening. Normally a person with Asthma has triggers. There are two main sections triggers fall under‚ a viral illness or an allergy. A viral illness is

There are a variety of structures which utilize concrete in their construction. The concrete structure may be reinforced‚ unreinforced‚ precast‚ or poured on site. The structure may only use concrete in a few elements or be almost entirely constructed from the material. The wide spread and diverse uses for concrete make it a substance which should be paid great attention to when looking to optimize structures in seismic regions and when analyzing data from earthquake reconnaissance. Though there

RESPIRATORY SYSTEM WEBQUEST 1. Describe the function of the nasal and oral pharynx for breathing. The ph arynx is a muscular funnel that extends from the back of the nose to the larynx‚ or voice box. The nasal pharynx’s function is to allow air passage through it. The oral pharynx has both respiratory and digestive functions since it serves as a passageway for air‚ food‚ and water. 2. Describe the structure and function of the epiglottis. The epiglottis is one of the nine cartilagous structures

Unarmed forces seems like an unlikely form of resistance‚ but in the context of the Holocaust‚ it represents small‚ individual acts of courage and bravery that resulted in a life or lives being saved. One of these acts included leaving the ghetto and living on the Aryan side‚ as a mean to stay alive‚ this was known as ‘passing’.
