Question
1. A biologist by training, gerontologist Frank Lee proposes that development throughout life is best understood as a series of genetically determined stages. Dr. Lee's views come closest to which model of life-span development?
D. Organismic
2. Random error theories propose that aging occurs as the result of:
D. replicative senescence.
3. The benefits of caloric restriction are thought to be due to its impact on
D. Sirtuins
4. Forward genetic research involves knocking out individual genes and observing the effect on the organism.
True or False?
5. Inhibiting telomerase may be a promising treatment for what type of condition?
D. Heart disease
6. The release of SASP by senescent cells may limit the growth of cancer cells in older age.
True or false?
A. Multidimensional.Explanation / Answer
This is closer to the organismic perspective which is suggestive that human beings have an inherent tendency for growth and development.
Random error theories of aging focus on the programmed and natural changes in cells and their organizations to create systems that operationally deteriorate and culminate into the explicit changes that we observe as part of aging.
Caloric restrictions have an impact on APOE since they are an enzyme related to the metabolism in body. Therefore caloric restrictions have a direct influence in its functioning
The given statement this true since it focuses on observing the actual role of Genes in determining human behavior and various other aspects of its dynamic functioning.
Inhibiting this may help in understanding the process of aging and developing cancer in a more effective manner. Therefore the answer is A.
