Effects of salinity on the survival of the Daphnia Introduction The Daphniidae daphnia is a freshwater crustacean from the branchiopod class that is common to most ponds‚ lakes‚ pools‚ streams and springs around the world. The water flea‚ as it is sometimes referred to‚ is very small in size growing to a length of less than ¼ inch‚ it has a flat back‚ a rounded belly‚ black round eyes and a pair of antennae (Kindersley‚ 2006). The Daphnia have leaf-like appendages used in respiration‚ filter

lessened risk of coronary heart disease – the number one killer in our society. Cardiovascular fitness is also referred to as cardiovascular endurance‚ cardio-respiratory capacity and circulatory fitness. Regardless of the word used to describe it‚ cardiovascular fitness is complex because it requires fitness of several body systems. Physical activity that leads to improved cardiovascular fitness has dramatic health and wellness benefits that extend well beyond heart disease risk reduction. It

I got behind‚ so I need to catch up. Section 2: Target Heart Rate My resting heart rate is 70 bpm. My target heart rate zone is 125 bpm to 167 bpm. Heart Rate Reflection Question: Were you able to maintain your workouts within your calculated target heart rate zone? Explain which activities you enjoyed most and which best helped you stay in your THR zone. Answer: With some of the workouts I was able to maintain my target heart rate zone‚ and the activities I liked the most was the sit and reach

through cellular respiration‚ and in turn‚ an athlete would heighten the intensity of the workout for a longer period of time becoming a better athlete. The VO2 Max of a person can be affected by mass‚ time it took to walk necessary distance‚ and heart rate. Each variable is in turn varied be age and gender. The greater the value for VO2 Max the greater the efficiency of the cardiovascular system. VO2 max plays a major role in the aerobic energy system because an increased VO2 max permits more oxygen

stepping up onto and down from the step before you begin the test. Each step has four beats: up-up-down-down. Males should perform the test with the metronome set for a rate of 96 beats per minute‚ or 24 steps per minute. Females should set the metronome at 88 beats per minute‚ or 22 steps per minute. 3. Set the metronome at the proper rate. Your instructor or a partner can call out starting and stopping times; otherwise‚ have a clock or watch within easy viewing during the test. 4. Begin the test

work goes on for a period of time and eventually leads to a certain degree of fatigue. Our concern is not so much with these move-ments as with the work demands of these movements on the player. We want to know how the work affects his body: his heart and lungs‚ muscles‚ blood‚ joints and all the other components of the machine that he is when he performs work. Our main concern is to examine the effect of work on the machine and to devise the means to make that machine more efficient. The greater
