Unlike Basal Metabolic Rate (BMR) Body Mass Index (BMI) is determined by an individual’s height and body weight. It is widely used to determine whether the individual belongs to a healthy weight group. In simpler terms body mass index is the value that represents the weight status of human body in relation of the amount of fat present in it. Similar to Basal Metabolic Rate now it is also possible to easily calculate body mass index using BMI calculator for men and women. Similar to BMR calculator

A brief history of Exchange rate of Bangladesh Since Bangladesh was the part of Pakistan called East Pakistan‚ shared the same currency and trade-policy history as the rest of Pakistan until the liberation of Bangladesh. Bangladeshi taka was created on January 1 1972. Pakistan rupees in circulation remained legal tender until replaced by the taka 1:1 beginning March 4 1972. The taka was set at par with the Indian rupee‚ and fixed to sterling at Tk 18.9677‚ or Tk 7.2797 to the United States dollar

Expiratory reserve volume decreased due to the rapid increase in breath rate. Normal resting breath rate is at an average 11.6 breaths per minute increased to 27 breaths per minute after exercise. The increase in BR causes expiration length to go below its normal 3 second interval. Therefore decreasing ERV by .6 Liters. Inspiratory reserve volume decreased due to the rapid increase in breath rate. Normal resting breath rate is at an average 11.6 breaths per minute increased to 27 breaths per minute

Brooke Strowd AP Biology Ms. Butler 28 January 2013 I. Title: Effect of a Catalyst on Reaction Rate II. Introduction: The basis of the experiment is the enzyme; an enzyme is a biological molecule that acts as a highly selective catalyst. By combining with a substrate‚ an enzyme is able to create a new product that helps the body function. (Ex. Lactose/Lactase) A substrate is a molecule an enzyme acts upon‚ the two combine at an area called an active site. This active site allows induced fit

Do you get the exact same results each time? How do the results compare to each other and to your prediction? What factors might contribute to susceptibility to the disease? 2. If the contagion rate is calculated as the number of new cases per day per total population‚ what would the average contagion rate be for Kold? Unlike some of the other interactive labs‚ this model has some randomness built in to reflect the real spread of a disease‚ which is a matter of probabilities. Despite this variability

Introduction The heart is an extremely important organ in the human body‚ and it must be able to adjust the heart rate for when a person is resting or for when a person is running. Heart rate is defined as the number of heartbeats per unit of time‚ usually per minute (Medicine-Net). The heart rate is based on the number of contractions of the ventricles. The pulse is defined as a bulge of an artery from waves of blood that course through the blood vessels each time the heart beats (Medicine-Net)

reported the findings of a study on teen suicide rates in Alaska. Using death certificates and U.S. census data to record trends in suicide rates among Alaskan teens ages 14-19‚ it was found that the teen suicide rate was 31.5 per 100‚000 persons each year. The study tested three hypotheses‚ the first being that the overall suicide rate of Alaska teens ages 14-19 during 1979-1993 would vary according to residence‚ gender‚ race‚ and age. Indeed‚ “suicide rates varied up to sixfold by race‚ gender‚ and local
