Human cells contain a vast number of chemicals. At any one time they carry out a multitude of chemical reactions to produce for example energy, molecules for the synthesis of new cells, or chemicals for secretion (e.g. cells that produce digestive enzymes). Describe the cellular compartmentalisation of some of these processes including the structure of the compartments and how this structure is optimised to its function. 500 words ...

Discussion 1: Reflections on Qualitative Research for Social Change Introduction: Social Change In the recent years, the pursuit for institutions, “practical researchers” and individuals to join in the crusade for social change has been remarkable; as many people around the world are reaching out to their neighborhoods as a member of the community to contribute to the common good through research, service, and educational opportunities ( Yob & Brewer, 2015. p.2). Social change constitutes a change in the nature, the social institutions, the social behavior or the social relations of a society, community of people, or other social structures (Walden University, 2016). Social change can be at the micro scale (that positively shape values, attitudes and behaviors) or at the macro scale (that positively shape economies, religion and families). The Essence of Social Change to a Walden Student Yob & Brewer (2015) observed that the term “social change” has been defined and analyzed across the academic disciplines, reflecting the particular perspective of that discipline and its research agenda. Prominent among the definition of social change are the concepts of social justice and equity which have been significant in discussions of social change in education, psychology, and social and cultural studies (Curry-Stevens, 2007; Drury & Reicher , 2009; Moely , Furco , & Reed, 2008; and Peterson, 2009, as were cited in Yob & Brewer (2015). There are as many definitions for social change as we have social scientists. However Hoff and Hickling -Hudson (2011), supporting the definition of Aloni (2002), provided the definition which places social change as “challenging trends of discrimination, exploitation, oppression, and subjugation displayed by groups who regard themselves as favored and, thus, take privileges for themselves and deprive other groups of the right to a dignified life” (p. 189). In this context, “ change” as is used in the “social change” is defined here in positive and value-laden terms that relate more particularly to the agents of social change than to others they might want to change. There is a great range and variation in the roles and positions that researchers takes up in research, as was observed by Ravitch & Carl (2016). Over the years ( more than 45 years), Walden University has produced career professionals with the opportunity to transform themselves as scholar-practitioners so that they can apply what they’ve learned to effect positive social change. Walden is focused on inspiring and celebrating the remarkable achievements of community members who continue to make a difference by addressing challenges where they live, in their professions, and in the world around them. This was a major factor that attracted me to pursue a programme at Walden. In our sub-region, (the sub-Sahara Africa), addressing the issue of social change from the national perspective has not been as significant relative to the.
