Pulley Lab Objective: The objective of this lab was to study the change in force using pulley systems. Hypothesis: I think with the weight and the different number of pulley systems being added each time the weight will be easier to lift every time we add a weight. Procedure: To do this lab you must first search different pulley system diagrams. Then you must find a way to make those pulley systems you have chosen work using four items. Pulleys‚ ring pole‚ a weight of your choice‚ newton

We are able to visualize‚ feel‚ smell‚ and hear the world around us due to a system called the sensory system. All around the surface of our body we have detectors that are known as receptors. These receptors‚ in the form of cells‚ are specialized to capture specific forms of energy- whether heat‚ light‚ chemical‚ or mechanical (1). The environmental cues that are detected by our receptors on the surface of our body are then transformed into electrical signals‚ or nerve impulses‚ that can be sent

Blood Composition. The following are components of blood - red blood cells‚ white blood cells‚ platelets and plasma (the liquid component). Red blood cells are the pinky white circles‚ the white blood cells are the big red blobs. Red blood cells do not have a nucleus because they do not divide and multiply Red blood cells are bi-concave‚ they are donut shaped. Red blood cells contain a pigment called haemoglobin which can react with oxygen to form the unstable compound‚ oxy-haemoglobin. Hb+4O2

Excellent work! A cell goes from diploid (2N) to haploid (1N) during meiosis I when pairs of homologous chromosomes split apart into different daughter cells. This haploid condition continues during meiosis II when sister chromatids split apart during the formation of four daughter cells. Score for incorrect answer: 0 General feedback 1 (May include media. Include graphic and file name): Remember that a diploid cell has pairs of chromosomes—each pair represents one chromosome that came from the

known as germ warfare — is the deliberate use of disease-causing biological agents such as bacteria‚ viruses‚ fungi‚ or biological toxins‚ to kill or incapacitate humans‚ animals or plants as an act of war. Biological weapons (often termed "bio-weapons" or "bio-agents") are living organisms or replicating entities (viruses) that reproduce or replicate within their host victims. Entomological (insect) warfare is also considered a type of BW. Biological weapons may be employed in various ways to

Blood a journey through the body. You might find yourself asking‚ what does blood have to do with digestion‚ respiration and circulation? Hopefully‚ after the presentation all of your questions will be answered. When a person thinks of digestion they usually think about what happens in the stomach. A lot has happened to digest the food way before it gets to the stomach. It starts in the mouth or oral cavity. It is a process called mechanical digestion. First‚ Mastication begins. Mastication

Disease: Ergotism Name of Pathogen: Claviceps purpurea Body System affected: Lymphatic/Immune sytstem‚ Digestive‚ Circulatory Bacterial Morphology: They are fungi that resemble small mushrooms in which the perithecia are embedded in the capitate tip. Reservoir: grains (specifically rye) and grass contaminated with ergot Mode of Transmission: Ingestion Symptoms of Illness: Symptoms include constriction of arteries and veins‚ rapid‚ weak pulse‚ precordial distress or pain muscle pain

Increased humidity put a great level of strain on the circulatory system. Humidity makes our bodies feel as if the temperature is higher. This is the result of a slower evaporation process because the air is filled with water and cannot hold much more. As a result‚ our bodies will produce sweat in order to cool off‚ but it will take longer to evaporate making the body only hotter and wet with sweat. An increase in temperature & humidity would mean a greater cardiac output to the skin to remove heat

increased. Magnification alone will not achieve this. For learning the techniques and ways in using light microscope‚ this experiment using the example of red blood cell and white blood cell. Red blood cells play an important role in your health by carrying fresh oxygen throughout the body. The oxygen gives your blood its bright red color. The cytoplasm of erythrocytes is rich in hemoglobin‚ an iron-containing biomolecule that can bind oxygen and is responsible for the red color of the
