M1- Discuss the role of energy in the body In our bodies we need energy so that we could do things that are possible such as; move our muscles‚ talk and all the other things that we do. Without energy all humans would be useless not being able to do anything. Energy is needed to extract the oxygen from the areas in our bodies and diffuse it into our bloodstream. As warm blooded we can only digest food and function if our bodies are at a certain temperature and have enough energy‚ and energy is

that heat can be transported in the atmosphere. Heat can be transported in the atmosphere by solar radiation. The earth then absorbs the solar radiation and then after that it will be change into heat‚ which will be suck back into the atmosphere. Conduction and turbulent eddies are other ways that heat raises back into the atmosphere. All heat being transported upward towards the atmosphere 2. What causes air pressure?

This spread is not performed continuously between the atrium and ventricle but by the specialized conduction system‚ beginning with the his bundle and which finishes with the purkinje network‚ that allows the wave of depolarization to cross the nonconductive wall wich separates the atrium and the

Etymology of the Word Thyristor A thyristor is a solid-state semiconductor device with four layers of alternating N and P-type material. The thyristor or Silicon Controlled Rectifier (SCR) was proposed by William Shockley in 1950 and supported by Bell Laboratories‚ formerly known as AT&T Bell Laboratories. It was developed in 1956 by power engineers at General Electric (G.E.) led by Gordon Hall and commercialized by G.E. ’s Frank W. "Bill" Gutzwiller (1). There are various types of thyristors;

Heat and Temperature Heat is often described by the average individual as being the change in temperature from hot to cold. “Often the concepts of heat and temperature are thought to be the same‚ but they are not.” Heat and Temperature‚ para. 2) Perhaps the reasoning behind the incorrect reasoning is that humans associate the two together because when heat is applied to an object the temperature rises. The kinetic theory of matter better explains the underlying cause as to what takes place

1. uncharged object such as paper? A charged object will attract an uncharged object until they touch‚ and then they will repel one another. When charged objects attract uncharged objects‚ such as when the negatively charged plastic comb or fur attracted the paper‚ the negatively charged comb/fur repelled some of the electrons in the paper. This results in a redistribution of charges in the paper so that one side is more negative than the other side. The net effect is that the paper is attracted

Explain why increasing extracellular K+ causes the membrane potential to change to a less negative value. How well did the results compare with your predictions? 3. Explain why a change in extracellular Na+ did not significantly alter the membrane potential in the resting neuron? 4. Discuss the relative permeability
