CHAPTER 1 INTRODUCTION: THEMES IN THE STUDY OF LIFE OUTLINE I. Life’s Hierarchical Order A. The living world is a hierarchy‚ with each level of biological structure building on the level below it B. Each level of biological structure has emergent properties C. Cells are an organism’s basic units of structure and function D. The continuity of life is based on heritable information in the form of DNA E. Structure and function are correlated at all levels of biological organization F. Organisms are

from the hydrolysis‚ that most of the hydrocarbon chains having a carboxyl group at one end indicates to me that these chains are mostly protein. The rest of the hydrocarbon chains that do not contain a carboxyl group are more than likely to be polysaccharides. c. Chapter 4: Question 11 Imagine that you are a pediatrician and one of your patients is a newborn who may have a lysosomal storage disease. You remove some cells from the patient and examine them under the microscope. What would you

they endure a process of straining. Their basic features are examined on the basis of their cytoplasmic lipid membrane‚ cell wall‚ and finally the presence of the bacteria in the cystol. Gram positive bacteria are mainly composed of a capsule polysaccharide‚ thick peptidoglycan layer‚ and flagellum which are present in certain species. It can either be aerobic or anaerobic. Gram positive bacteria have a simpler cell wall‚ with a large amount of peptidoglycan. Peptidoglycan is a polymer composed of

Enzyme is a type of protein that speed up the rate of reaction of living organisms. Enzyme also acts as a catalyst for specific chemical reaction by converting a specific reactants into a specific product. The enzyme activity will also be affected by temperature and pH value. In this experiment‚ enzyme was placed in carbohydrate solution at different temperature to identify unknown carbohydrate solution. The enzyme that involved in the reaction is salivary amylase. The action of amylase on starch

As humans‚ we are the most dominant species in the world. We have the ability to walk upright‚ grasping thumbs‚ and large brains. This helps us to live and be successful on earth. But‚ these advantages we have didn’t happen overnight‚ they occurred during the hominine evolution. The skull‚ neck‚ spiral column‚ hip bones‚ and leg bones of the early hominine species changed shape in ways that later enabled species to walk upright. The evolution of dipedal‚ or two-footed‚ locomotion was very important

The cell is the fundamental structural unit of all living organisms. Some cells are complete organisms‚ such as the unicellular bacteria and protozoa; others‚ such as nerve‚ liver‚ and muscle cells‚ are specialized components of multi-cellular organisms. Cells range in size from the smallest bacteria-like mycoplasmas‚ which are 0.1 micrometer in diameter‚ to the egg yolks of ostriches‚ which are about 8 cm (about 3 in) in diameter. Although they may differ widely in appearance and function‚ all cells

Cell Biology 1 – Prokaryotes & Viruses * Eukaryotes have a membrane whereas a prokaryote has no nuclear membranes. Both have a double stranded DNA. * The two main types of prokaryotes are bacteria and Archaea and eukarya are types of eukaryotes. * Archaea are more closely related to eukaryotes. * Prokaryotes have a membrane and nucleoid and most have a cell wall. * There are 3 main types of shapes of prokaryotes: * Bacillus – rod shapes * Spirilum – spiral shaped

Acne Vulgaris is a disease of the epidermal pilosebaceous follicles involving inflammatory and non-inflammatory clinical lesions in the skin. The multifactorial pathogenesis of acne includes sebum‚ ductal epidermal hyperproliferation‚ colonization of Proprionibacterium acnes and inflammation . Research has shown‚ P. acnes is not the cause of Acne Vulgaris‚ but is a significant contributing factor to the inflammation stage of this disease .
