Can tegu lizards maintain an elevated body temperature during their reproductive season? Experiment: Dr. Glenn Tattersall and a team of researchers in Rio Claro‚ Brazil studied changes in the heart rate and body temperature of tegu lizards (Salvator merianae)‚ by implanting lizards bred in captivity with specialized electronic chips. One group of lizard lived in an entirely outdoor environment for one year. Three other groups that were subjected to alternating indoor and outdoor environments over

WHY DOES THE COLOUR LEAK OUT OF COOKED BEETROOT? PLAN Hypothesis Temperature has an effect on the leaking of the colour from beetroot. This means that as the temperature is altered there will be a change in the rate of colour leakage. Scientific Background Beetroot is a very familiar vegetable and is commonly known as beet. It is famous in most recipe books that advice that its outer skin is not to be removed to avoid getting red dye in the cooking water. If we look at the internal structure

Examples of extreme environments on Earth are hot geysers and oceanic thermal vents‚ Antarctic sea ice‚ and oxygen-depleted rivers and lakes. Organisms that have evolved special adaptations that permit them to live in extreme conditions are called "extremophiles."

The Effect of Temperature on Solubility By Aviraj Singh Rogers 2 Background: The solubility of most solid substances is generally said to increase as the temperature of the solvent increases. However‚ some substances‚ such as ytterbium sulfate‚ do the opposite. This can be explained through the Second Law of Thermodynamics which states that “in all energy exchanges‚ if no energy enters or leaves the system‚ the potential energy of the state will always be less than that of the initial state”

1. Temperature: Put some hot water‚ warm water‚ and cold water in three bowls. Just use water from your faucet‚ and please be sure that the hot water is not too hot to touch! Place a finger in the hot water and a finger of the other hand in the cold water. After a few seconds‚ place them both in the warm water. Describe the sensations. Can you trust your senses for measuring temperature? Explain your answer. Placing finger A(pointing finger on left hand) in the “hot” water‚ my finger felt a hot

The objective: In this experiment‚ I decided to find out how temperature would affect endothermic reactions compared to exothermic reactions. An endothermic reaction absorbs energy in the form of heat. This reaction feels cold because it is taking heat away from its surroundings. It also releases gases. An exothermic reaction is a reaction that releases energy as heat. Since the energy is released‚ the exothermic reactions feel hot. Methods/Materials I did three experiments. I mixed lemon juice

The average temperature in Santiago is 14.4°C with January being the warmest at an average temperature of 21°C and June and July being the coolest months‚ both with an average temperature of 8°C. For what is considered to be fall and winter in the northern hemisphere‚ is spring and summer in the southern hemisphere‚ therefore that is when Santiago’s climate is at its peak. It can be noticed that from January to June and July‚ the temperature starts to change at a not so slow

I am choosing to study how the PSI (pounds per square inch) of a football is affected by the temperature. I chose to study this because I like football and I always pondered this question. I believe that this is a worthwhile question to study because these studies can help improve the game as the weather gets colder. As air cools‚ it expands‚ so when a football gets colder‚ the air inside it expands. This expansion causes the air pressure to decrease. The air pressure decreases because the molecules

For this experiment‚ there will be an optimal point for each factor. I believe that the optimal temperature for the enzyme sucrase will be 37°C because that is the point where the temperature increases the rate of reaction to its greatest point without denaturing it. For the pH test‚ I think that the optimal pH for sucrase will be the pH of 7 because it is neutral so it won’t affect the charge in a negative or positive way. For the denaturation test‚ I think that the optimal treatment for the enzyme

CHAPTER ONE 1.0 INTRODUCTION 1.1 Student industrial working experience scheme (SIWES) Students Industrial Work Experience Scheme (SIWES) is one of the industrial training fund(ITF) programmes. It was designed to give Nigerian students studying occupationally-related courses in higher institutions the experience that would supplement their theoretical learning. This paper attempts to examine the role of the university in the implementation of SIWES programme in Nigerian Universities. The
