Makalah Biologi Percobaan Reaksi Hidrogen Peroksida dengan Katalase Penulis: Jancolin Yani Pendahuluan Seperti yang kita tahu bahwa hydrogen peroksida yang dihasilkan oleh sel-sel didalam tubuh kita akibat metabolism sel akan terpecah menjadi gas hydrogen dan oksigen dengan adanya keberadaan enzim katalase. Zat hydrogen peroksida sangat berbahaya bagi tubuh dalam kuantitas yang banyak oleh karena itu harus dipecah dan dikeluarkan. Sebagian besar zat hydrogen peroksida

Prediction I think that the speed of the cart will decrease as more weight is added on top of the cart. This is because the more weight that is placed on the moving vehicle/object‚ the more downward force is produced. This would increase the friction between the wheels of the cart and the ramp’s surface. The increase in friction would slow down the moving object (cart). Apparatus Trolley/cart- this is essentially a wooden block with wheels and a rubber end‚ to provide the collision with a

constant speed AC motor‚ while the HP stage is driven by a variable speed DC motor. This feature allows variation of the intermediate pressure. Each stage is provided with its own dynamometer. At compressor’s inlet there is an airbox with a sharp-edged orifice for flow measurement. An intercooler is provided between the two stages‚ and an intercooler between the second stage and the pressure vessel. Connected to the pressure vessel is an exhaust pipe with a throttling valve and a calibrated flow

The Perspiration Workout Unit of the ‘Passive Anaerobic and Aerobic Exercise Assist System for the Inactive and Sedentary Population’ is essentially an infrared dry sauna‚ the heaters produce infrared rays that superficially heat skin and other exposed surfaces but not the air.[7]‚ which is absorbed by the surface of the skin.[1] A study of patients with rheumatoid arthritis and ankylosing spondylitis showed a reduction in pain‚ stiffness and fatigue during infrared sauna therapy.

Gimme Experimental is a short experiment but tests a very interesting psychology concept: the endowment effect. The endowment effect simply is the expectation that if a person owns something they place a higher value to it. Conversely‚ there is another psychology term called the reverse endowment effect. This is the complete opposite of the endowment effect‚ which means a person would place a higher value for someone else’s possession. Interestingly‚ this experiment does not take long at all. Kids

Title Soda Ash: Great for the economy but detrimental to the body; So why is it involved in everyday life? Abstract Sodium carbonate‚ Na₂CO₃‚ commonly known as soda ash is used in the manufacturing of many economically important products such as the manufacturing of glass‚ chemicals‚ paper and detergents. Since sodium carbonate has a strong base‚ it is commonly used to neutralize acidic effects. Soda ash has a high pH in concentrated solutions and can irritate the eyes and skin as well

The purpose of this experiment was to determine if cars on Woody Hayes Drive needed additional traffic control to reduce speeding. The sections that follow describe the process‚ calculations and answers to this experiment. Section 2 will describe the tools and step-by-step processes that’re required to replicate this study.

according to a stunning experiment of a recognized institute in Japan‚ a chimpanzee knows the food is hidden under a stone and reach it effortless. Then‚ researches replace stone with a heaviest stone and the chimpanzee could not take the food alone. If two chimpanzees know about food‚ they work together. At first‚ they do not synchronize their collaboration in pulling the heaviest stone but eventually‚ they figure out reward of synchronizing to their pulling. Same experiment is again performed with
