Assignment 1. 1. Summarise the main development of a child from the age range 0-2 years‚ 3-5 years and 5-8 years. 0-2 Years Newborn babies grow extremely quickly. During ‘Infancy’‚ which lasts from birth to eighteen months‚ babies change from a helpless newborn‚ to a child who can lift up their own head at three months‚ sit up unsupported at six months‚ walk at sixteen months and kick and throw a ball at two years old. Newborn babies actually lose some of their birth weight to begin with

Exercise 2: Skeletal Muscle Physiology: Activity 3: The Effect of Stimulus Frequency on Skeletal Muscle Contraction Lab Report Pre-lab Quiz Results You scored 100% by answering 4 out of 4 questions correctly. 1. During a single twitch of a skeletal muscle You correctly answered: b. maximal force is never achieved. 2. When a skeletal muscle is repetitively stimulated‚ twitches can overlap each other and result in a stronger muscle contraction than a stand-alone twitch. This phenomenon is known as

Eliciting (Generating) a Nerve Impulse 1. Why don’t the terms depolarization and action potential mean the same thing? Depolarization has to do with surfaces becoming more negative or positive and reaches a certain point called a threshold. When the threshold is reached‚ an action potential is initiated. 2. What was the threshold voltage in Activity 1? The threshold voltage in Activity 1 was 3.0. 3. What was the effect of increasing the voltage? How does this change correlate to changes

Under these conditions‚ does the fluid flow through the nephron? >>No! No urine was collected which indicates no fluid flows through the nephron. 3. What is the glomerular filtration rate? >>The glomerular filtration rate is 0 which means the glomeruli are not carrying out any filtration task. 4. How does it compare to your baseline data‚ and why? >>The glomerular filtration rate in baseline data is 124.99 which indicate functional glomeruli. The data support
