Discuss the validity‚ reliability and physiological foundations of a test versus a predictive maximal oxygen uptake test. Abstract The aim of this study was to assess the validity‚ reliability and physiological underpinnings of an actual VO2max test in comparison to a predictive maximal oxygen uptake test. Eight male subjects with the following physical characteristics‚ mean and standard deviation age 19.75 ± 0.71 year; weight 72.15 ± 11.93 kg; height 1.77 ± 0.11 m performed an incremental treadmill

energy in a series of reactions that take place inside components of the cell. The stages are briefly explained below as were briefly explained in part A‚ the process then goes through‚ glycolosis‚ link reaction and then the Krebs cycle. The volume of CO2 that is produced in the Krebs cycle is important as this is the dependant variable. Enzymes are proteins that can effectively increase the rate of a reaction by lowering the required energy (activation energy) needed in order for the reaction to occur

TRANSPIRATION DESIGN LAB Transpiration is the process through which water is lost from a plant. Water is taken into a plant through roots and root hairs by osmosis‚ and it exits the plant through stomata. Transpiration helps the diffusion of both O2 and CO2 plus it helps the movement of water throughout the plant. There are some factors that affect the rate of transpiration of the plant. Those factors are mainly humidity‚ soil water supply‚ sunlight‚ temperature and wind. Any alteration

accumulate different metal anions in the air than other organisms‚ like plants do‚ for example. Lichens attract toxic metal ions. An ion is a charged atom. If the ion has a positive charge‚ it is a cation. An ion with a negative charge is an anion. During the ion exchange process‚ Hydrogen‚ an anion‚ is released and metal cations move in. This process occurs when lichens are exposed to polluted air. When the lichens are dropped into any of the metal solutions‚ their cell wall releases the methylene

How do limiting factors affect the rate of photosynthesis? Rate is the measurement of an amount of product or time. In the case of the rate of photosynthesis‚ it is measuring the gain of mass or growth over time. If the plant is an aquatic one that grows in water the rate of photosynthesis can be measured by counting oxygen bubbles or the volume of gas produced in a measured time period. A limiting factor is something that is present in the environment that has a short supply and because of that

Relationship between algal cover and water chemistry in rockpools Ahmad Mukhris Ahmad Mahadzir ABSTARCT Intertidal rockpool is one of the harshest environment in marine ecosystem. Most of the organisms living in it has to have adaptions to survive in harsh conditions‚ especially algal. A research was done to see if abiotic factors such as temperature‚ dissolved oxygen‚ temperature and pH value could have a significant correlation with total percentage of algal cover. Initial hypothesis was

Light Lab Introduction: The purpose of this lab is to observe how influential light is to the construction and/or use of CO2 and O2 amongst plants. This can be examined by experimenting the effects of plants under both light and no light. In order to begin this experiment you must begin by wrapping the “BioChamber” with aluminum foil to prevent light from coming through to the leaves‚ however‚ once the lid has been covered you are to poke holes so you can insert the sensors. Next‚ you will
