Textbook Question
Chapter 11, Problem 11TYU
SCIENCE, TECHNOLOGY, AND SOCIETY The aging process is thought to be initiated at the cellular level. Among the changes that can occur after a certain number of cell divisions is the loss of a cell's ability to respond to growth factors and other signals. Much research into aging is aimed at understanding such losses, with the ultimate goal of extending the human life Span. Not everyone, however, agrees that this is a desirable goal. If life expectancy were greatly increased, discuss what might be the social and ecological consequences.

Students have asked these similar questions
Discuss the importance of Stem Cells.
How does the scientists harvest the stem cells in our body?
Differentiate the embryonic stem cells and the adult stem cells
Virtually every multicellular organism, including you, goes from a single-celled fertilized egg to a large, multicellular organism. In this post you will demonstrate an understanding of how the process of mitosis leads to the growth of an organism and how cell differentiation results in the wide variety of specialized cells found in a multicellular organism.
How does mitosis explain the process of growth? Can growth occur only through mitosis?
If every cell in your body is a copy of that original fertilized egg, how is it that some cells are so different than other cells? How does differentiation help explain these different cell types? Cite some specific examples of differentiated (specialized) cells. Please remember to add a question to engage your classmates in the discussion.
Which statement about cellular aging is TRUE?
Cellular aging is unrelated to the first law of thermodynamics
Oxidative stress prevents cellular aging.
cellular aging is the result of an intracellular accumulation of damaged proteins
Telomere length is maintained indefinitely in all cells, causing cellular aging.

- Please answer this following question in your own words: Question 1: As an individual ages, a constellation of changes slowly occur. As the process proceeds tissue and organ function can be slowly compromised. Identify and discuss two factors that contribute to aging and the subsequent loss of cellular and tissue integrity.
