CELL THEORY – STEM CELLS Stem cells are a large focus of study in today’s biomedical world. “They are cells that exist in an undifferentiated state‚ and transform into differing tissue types depending on what the cells surrounding them are‚“ (National Institute of Health‚ 2012). Stem cells have the remarkable potential to develop into many different cell types in the body during early life and growth. In addition‚ they also serve as an internal repair mechanism inside many tissues‚ dividing without

and animal cells have several differences and similarities. For example‚ animal cells do not have a cell wall or chloroplasts but plant cells do. Animal cells are round and irregular in shape while plant cells have fixed‚ rectangular shapes. Animal Cell Plant Cell Cell wall Absent Present (formed of cellulose) Shape Round (irregular shape) Rectangular (fixed shape) Vacuole One or more small vacuoles (much smaller than plant cells).

are important to understanding cell injury and cell death regardless of the injuring agent” (Heuther & McCance‚ 2012). Cellular injury arises when a cell is unable to sustain homeostasis. The injury can be reversed if the cell can recover from whatever damage was done but if it does not recover the cell will die. The three common forms of cell injury are hypoxic injury‚ free radicals and reactive oxygen species injury‚ and chemical injury. The most common form of cell injury is hypoxic injury‚ or

ECONOMIES OF SCALE Economies of scale are the cost advantages that a business can achieve by expanding the scale of production. That is‚ when long-run average costs (LRAC) fall. Overhead costs (fixed) are spread over more units produced. Overhead costs (fixed costs) are spread more when more units are produced. These lower costs are an improvement in productive efficiency and can benefit consumers in the form of lower prices. Units produced Total cost Average cost

Geologic Time Scale Introduction Understanding geologic time is critical to relating events in Earth’s history to those of today. Scientists use several forms of the geologic time scale to classify the age of objects and to become familiar with other events occurring simultaneously. In this lesson you will: · Examine how the geologic time scale summarizes Earth’s history · Analyze physical and biological changes that have occurred over time · Identify major events that occurred in geologic

4 6 = purchase or behavioural intent scales A Behavioural intent scale has been used for number 4 and 6. It is a scale designed to assess the likelihood of a consumer purchasing‚ or behaving in a certain way. (Mullet and Karson 1985). This method was chosen to assess whether the respondent would agree or disagree with the given statement‚ based on their behaviour towards Kate Moss.

Qualitative information is obtained from a nominal scale. This means objects are classified by name only. Counting is the only operation that can be performed on a nominal scale. Examples of nominal questions that may be used are: state of residence; gender; or hair color: blonde‚ brown‚ red‚ black. Ordinal Ordinal
