placed in a solution of lower water potential‚ water will leave its cells by osmosis. In this case‚ the plant tissue will decrease in size as the plant cells shrink upon losing water. For this activity‚ you are required to design and perform an experiment to determine the water potential of potato tissue using sucrose solutions of different concentrations. The water potential of potato tissue will be expressed in terms of the concentration of sucrose solution. Apparatus and Materials 1 ml pipette

respire faster. Meaning- they need more oxygen and glucose and release more carbon dioxide. A faster breathing rate means that oxygen can be taken into the body at a faster rate and carbon dioxide can be released faster. Cardiac output = stroke volume x heart rate Effects of exercise: Ventilation – breathing Respire – release of energy from food/chemicals Anaerobic respiration … is release of glucose without using oxygen. This produces lactic acid. glucose = lactic acid

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

The Feeding Behavior of the Protist known as Tetrahymena vorax Abstract The purpose of this experiment was to study the rate of phagocytosis of the specific protist known as Tetrahymena vorax. This certain kind of protist feeds at a normal rate when conditions are normal. We began the experiment of understanding how Tetrahymena feeds at normal temperatures. Doing so‚ we allowed the Tetrahymena to feed at specific time limits and then killed the protist with gluderaldheyde to detect how much

Aesthetics is the study of the mind and emotions in relation to the sense of beauty. This philosophy is very well explained in Virginia Postrel¡¯s essay‚ ¡°Surface and Substance¡±. In the essay‚ Postrel challenges the separation of surface and substance with examples of acts of consumptions‚ which she describes as an engagement with beauty. There are many reasons that drive people towards consumptions. It is important to be socially accepted‚ even if it requires changing the way one looks. Some

Abstract: The focus of this experiment was to identify unknown bacteria provided. The identification of unknown bacteria is beneficial in many aspects of the research of microorganisms and also aids physicians to treat patients correctly. Various tests were performed to provide the fermentation abilities‚ presence of particular enzymes‚ and biochemical reactions. Qualitative observations were made on the tests in identification process. The data from experimentation provided sufficient results

INTRODUCTION: These experiments helped us learn the factors that were involved in the growth of the bacteria that increased our study towards their genetic‚ physical and metabolic characteristics. We used Escherichia coli and Bacteriophage T7 to identify and analyze their identical life cycle and replication that was involved in their process of growth. As‚ growth for any bacteria
