Written Assignment – Project‚ Part D I believe that WHS is extremely important and is an essential part of every day at work. Apart from the basic instinctive regard for our health and safety‚ there are many reasons why WHS should be priority in the workplace. They include: • Legal Obligations • Community expectations that organisations have a responsibility for those that work for them • Ensures a safe working environment for all staff • Insurable costs such as workers’ compensation premium that

LABORATORY REPORT Activity 2: Twitch Contractions and Summation PREDICTIONS Effect of Muscle Fiber Length on Contraction 1. As muscle fiber length increases: contraction force increases‚ becoming maximum at an optimal length‚ then decreasing at longer lengths. Effect of Stimulation Frequency on Contraction 2. As the frequency of stimulation increases‚ the force of contraction: increases. MATERIALS AND METHODS Measurement of Threshold Stimulus 1. Dependent Variable: contraction force

Animals have three types of muscles; skeletal‚ smooth‚ and cardiac. This lab however is only concerned with skeletal muscle. A special characteristic of skeletal muscle is their ability to contract or shorten via thin (actin) and thick (myosin) filaments (Flanagan‚2017). This gives a striated appearance which is a key distinguishing characteristic between other types of muscle (Flanagan‚2017). Skeletal muscle is also multinucleated. Skeletal muscle needs plentiful amounts of energy to be able to

to help your body replace worn out cells. Mitosis has five phases‚ six if you include Cytokinesis. The phases of Mitosis are Interphase‚ Prophase‚ Metaphase‚ Anaphase‚ and Telophase. These phases all work together in order to help recover worn out muscles ‚ skin and other types of cells. Mitosis is when one cell divides into two daughter cells. Mitosis is very useful for organisms. Without Mitosis organisms would not be able to repair cuts and could result in death. It is also very helpful to organisms

Hess’ Law of Heat Summation Hess’ Law states that: "The enthalpy change for any reaction depends on the products and reactants and is independent of the pathway or the number of steps between the reactant and product". BASICALLY: Hess’ Law states "the heat evolved or absorbed in a chemical process is the same whether the process takes place in one or in several steps" >This is also known as the "law of constant heat summation". All it means is that no matter how many steps the chemical

isolated frog muscle could be made to contract when the sciatic nerve was irritated with a metal object‚ conducted the first muscle experiments between 1661 and 1665. Later‚ between 1737-1798 Luigi Galvani determined that frog muscle responded to electrical currents. The kymograph‚ which was invented in the late 1840’s lead to the revolution of experimental physiology because it enabled muscle contractions to be analyzed and recorded. The muscle cell or fiber is the basic unit of a muscle. The frog gastrocnemius
