The problem that we are solving is “How does the temperature outside affect the speed and heart rate of the runner?” We chose this to investigate “How does the temperature outside affect the speed and heart rate of the runner?” because we both play sports that require lots of running (Track and Field and Soccer.) Therefore‚ when running track outdoors the weather at the beginning of the meet may be colder‚ than the end when it’s most likely hotter. As well as a soccer tournament‚ you may play a tournament

Abstract This experiment was designed to answer the question does temperature affect the amount of osmosis? The hypothesis predicted was that the higher the temperature the more osmosis would occur‚ but too high the osmosis would halt due to enzyme and substrate overheating and losing shape. After research and class time it was concluded that osmosis is a passive transport and would not require energy or enzymes due to it going from high to low concentrations with the gradient

When a beetroot cell is exposed to various kinds of temperatures‚ its plasma membrane is affected and may change in structure resulting in the leaking of betacyanin. If the temperature changes‚ then I would expect to observe that there would be a change in the concentration of betacyanin that has leaked from a beetroot cell. In specific‚ at high temperatures‚ the phospholipids that make up the plasma membrane of the beet root cell become progressively more destabilized causing them to transform into

atmospheric pressure is suspended from the ceiling of a large room. The steam temperature entering the pipe is 120 oC‚ and the air temperature is 20 oC. The overall heat transfer coefficient on the outer surface of the covered pipe is 10 W/m2.K. if the velocity of the steam is 10 m/s‚ at what point along the pipe will the steam begin condensing and what distance will be required for the steam to reach a mean temperature of 100 oC? Question 2: Consider a horizontal‚ thin walled circular tube

LAB 9: DATE: 25TH January‚ 2011. FORM CLASS: L6 3 SUBJECT: Biology TITLE: Enzymes AIM: To investigate the effect of temperature on the enzyme lipase INTRODUCTION: The phenomenon of catalysis makes possible biochemical reactions necessary for all life processes. Catalysis is defined as the acceleration of a chemical reaction by some substance which itself undergoes no permanent chemical change. The catalysts of biochemical reactions are enzymes and are responsible for bringing about almost

Memorandum To: Urban Planning Department From: Name Subject: Rise of Temperature in Urcity Date: Introduction Agricultural areas all over the world are feeling the effects of suburb expansion. The cities growth is having an effect on the ability of land‚ water‚ and animals. With city growth will create problems such as climate‚ land‚ and geographical changes (Hillel‚ 1995). Critical Findings The agricultural areas of UrCity are being forced further out into the desert basin due

2. How is the colour related to surface temperature of the star? The correlation between the surface temperature of a star and its colour is due to the phenomena known as black body radiation .A star is a black body‚where it aborbs all the radiation falling upon it.AS its temperatures gets hotter thanits surrounding‚the star radiates its on electromagnetic radiation‚known as black body radiation. This radiation is distributed unevenly but contionously through multiple wavelengths of the electromagnetic
