CULTURE What Makes Us Strangers When We Are Away from Home? Culture – is an abstract concept. You can’t touch it or see most of it‚ and much of it can’t be measured. But it has molded each of us into whom and what we are. The way we dress‚ what we eat for dinner and how we eat it‚ how we speak‚ what color we paint our houses‚ and what we think about these things. - is dynamic and adaptive. COMPONENTS of CULTURE 1. Cognitive Process Learning‚ knowledge and perceiving What people think‚ how

SKIN AND THE INTEGUMENTARY SYSTEM CHAPTER 6 Your Name () OVERVIEW This chapter describes the skin and its appendages. It explains the structure and function of the layers of skin (dermis and epidermis) and the hair‚ nails‚ and sweat glands. This chapter also explains how the skin helps regulate body temperature and how it responds to environmental factors‚ such as sunlight and injury. Study of the integumentary system is essential to understanding how the body controls interaction between

CHAPTER ONE 1.0 INTRODUCTION This report is a practical experience acquired by me in the course of my industrial training at Druckfarben Nigeria Limited (DFN) under the student industrial work experience scheme (SWIES). In the earlier stage of science and technology education in Nigeria‚ students were from their respective institutions without any technical knowledge or working experience. It was in this view that students undergoing science and technology related courses were mandated in different

cells is attached to the basement membrane for support and connection. Part of the basement membrane is secreted by the epithelial cells. There are nerve supplies to epithelia but they are supplied with oxygen and nutrients from deeper tissues by diffusion. Seeing as they are surface cells‚ they’re exposed to friction‚ their capacity for growth and repair is greater than other tissues and this usually occurs during sleep. Simple epithelia: Simple epithelia cells can be either squamous‚ cubiodal‚ columnar

Depending on what stressors there are the cellular membrane can become damaged. The objective of this experiment was to examine the struc

Introduction to Biochemistry Biochemistry : a multidisciplinary science that explores the chemistry of living organisms and molecular basis for changes occurring in living cells. Principal areas of Biochemistry 1. Struture and Function of Biomolecules Based on structure depend the function (structure function relationship) Example: Hemoglobin S differs from regular adult hemoglobin (hemoglobin A) by just one single amino acid. A valine replaces a glutamine in the 6th position of the beta

Anatomy Outline Notes Exam 1 Developmental Anatomy – is the way anatomy changes over time in a single species -somites are segmental blocks found in embryos that form muscles & vertebrae etc. Comparative Anatomy – is the comparison of anatomies between different species. -all known vertebrates have common feature (skull & vertebrae): this leads to evolutionary theory. Hierarchy of Structural Organization -Body -> System -> Organ -> Tissue -> Cells -> Chemical/Molecular

leaf. Therefore‚ photosynthesis takes place in the chloroplasts which are present in the palisade cells (found near the top of the leaf.) (fig: 1 ) As chloroplasts contain a green pigment called chlorophyll‚ which absorbs light energy needed to make photosynthesis happen. The equation for this reaction is: 6CO2 + 6H2O+ light energy ---> C6H12O6 + 6O2 Sugars created in photosynthesis can be later converted by the plant to starch

The Digestion process The digestive process is important in maintaining the lives of living organisms and in providing them with needed energy and nutrition. Groups of organs‚ such as the mouth‚ esophagus‚ stomach‚ intestines‚ pancreas‚ and gal bladder work together to perform this complex task. Digestion is the process of breaking down food from large molecules into small ones to make it easier for absorption. The three major steps involved in the digestive process are ingestion‚ digestion‚ and
