APBIO5._____________________.FR23 2014 December 3‚ Respond to the following. 1. Distinguish genetic drift from gene flow in terms of how they occur and their implications for future genetic variation in a population. Genetic drift‚ defined as the process in which chance events cause unpredictable fluctuations in allele frequencies from one generation to the next‚ can increase or decrease variability within particularly small populations. Certain genotype/phenotype frequencies‚ for example‚ may

Triphosphate Phosphocreatine (ATP-PC) energy system is the most dominant for the sport of tennis. When participating in tennis‚ you will need to execute explosive bursts of speed. This means you will be working at 100% for a short amount of time; while you complete a serve or return or‚ during the period in which you move to hit the ball. These efforts would only last for less than 5 seconds‚ and when working at such a high intensity for this amount of time you are using your ATP-PC system. A whole

To describe how the concentration of an enzyme affects its ability to work. Hypothesis: Depending on the concentration of the catalase which the disk is soaked in‚ it will have a direct correlation on the rate of hydrogen peroxide being broken down into oxygen gas. Prediction: Since the rate of reaction can be lowered by the addition of
