29/09/2007 Activity 1: hair structure a) Describe‚ in detail‚ the structure of a hair identifying the 3 layers. Hairs are dead structures that are made of hardened protein called keratin. Keratin provides the body with a protective toughness for its entire surface. Hair is comprised of 3 layers these are as follows the cuticle‚ the cortex and the medulla. The cuticle is the outer layer of the scale cells with each scale overlapping each other towards the tip of the hair. This

Fluid‚ Electrolyte‚ and pH Balance 1. The maintenance of normal volume and composition of extracellular and intracellular fluids is vital to life. List and briefly describe the kinds of homeostasis involved. In males and females‚ intracellular fluid has a greater proportion of total body water than does extracellular fluid. Give-and-take between the ICF and the ECF happens across plasma membranes by osmosis‚ diffusion‚ and carrier-mediated transport. The kinds of homeostasis involved are fluid

Being accused of something you didn’t do is not only unfair‚ but also injustice. Although fingerprints are crucial evidence and data of a case‚ it’s not the only piece of information available. While trying someone for a case‚ it’s only lawful if the jurors understand the process and basic principles of the technique. However‚ the system of unskilled jurors can be improved. These days‚ fingerprinting people seems pretty cunning. With a DNA database‚ fingerprints seem like a reliable source. For

"seeing-doing" because your muscles seem to "know" and "remember" just what to do. What you’re learning now is speed‚ i.e. how to perform the task carefully and quickly. That’s muscle memory. Scientists call this "kinesthetic memory" or "neuro-muscular facilitation" and they speak of "sensory-motor" learning‚ since you are combining sensing input‚ i.e. what you see with your eyes‚ with motor output‚ i.e. what you do with your body. Of course‚ during the "drill-and-practice"‚ your muscles aren’t really memorizing

The White Man’s Muscles In today’s society‚ the naked white male body is found everywhere. It can be seen in print ads‚ including clothing catalogues‚ TV commercials‚ and especially in movies‚ yet the prevalence of the naked white male body is something that has only been embraced since the 1980s.

PRINCIPLES OF MANAGEMENT III DEFINE ORGANIZATION; DISCUSS THE CHARACTERISTICS‚ IMPORTANCE AND ITS SIGNIFICANCE. INTRODUCTION: The word is derived from the Greek word ORGANON‚ itself derived from the better-known word ERGON which means "organ" – a compartment for a particular task. ORGANIZATION is the foundation upon which the whole structure of management is built. It is related with developing a frame work where the total work is divided into manageable components in order to facilitate the achievement

Anatomy and Physiology are probably 2 of many different sciences necessary for the best understanding of the human body and how it functions. So I believe that in order to compare two things‚ you need to explain what each are first. ANATOMY is the study of the human body. It can also be defined as being the study of how various parts of the body interact and work together. PHYSIOLOGY is the study of how living organisms function. That includes nutrition‚ movement‚ and reproduction. So you are pretty
