1. All of the aboveP. 40

Hi,no comment on the discussion questions very good questionthank you

A and BHypertrophy results from an increased workload imposed on an organ or body part and is commonly seen in CARDIAC and SKELETAL MUSCLE tissue, which cannot adapt to an increase in workload though MITOTIC DIVISION and formation of more cells (p. 31).

Genes that determine the differentiating characteristics of a particular cell typeIn general, the genes expressed in all cells fall into two categories: housekeeping genes that are necessary for the normal function of a cell, and genes that determine the differentiating characteristics of a particular cell type. In many adaptive cellular responses, the EXPRESSION OF THE DIFFERENTIATION GENES IS ALTERED, whereas that of the housekeeping genes remains unaffected (p. 29).

1. occurs in tissues with cells that are capable of mitotic division-hyperplasia refers to an increase in the number of cells in an organ or tissue. it occrs in tissues with cells that are capable of mitotic division, such as the epidermis, intestinal epithelium, and glandular tissue. nerve cells and skeletal and cardiac muscle cells do not divide and therefore have no capacity for hyerplastic growth. there is evidence that hyperplasia involves activation of genes controlling cell proliferation. as with other normal adaptive cellular responses, hyperplasia is a controlled process that occurs in response to an appropriate stimulus and ceases after the stimulus has been removed (p. 31).

1. none of the above-fatty changes are linked to intracellular accumulation of fat. when fatty changes occur, small vacuoles of fat disperse throughout the cytoplasm. the process is more ominous than cellular swelling, and although it is reversible, it usually indicates more severe injury. these fatty changes may occur because normal cells are presented with an increased fat load or because injured cells are unable to metabolize the fat properly. in obese people, fatty infiltrates often occur within and between the cells of the liver and heart because of an increased fat load.

1. is initiated by mitochondrial or extrinsic pathways-cell death can involve apoptosis or necrosis. apoptotic cell death involves controlled cell destruction and is involved in normal cell deletion and renewal. apoptic cell death, which is equated with cell suicide, eliminates cells that are worn out, have been produced in excess, have developed improperly, or have genetic damage. it also provides the space needed for cell replacement. initiation of apoptosis occurs principally by sinals from 2 pathways: intrinsic (aka mitochondrial pathway) or extrinsic (receptor-initated) pathway.

To reverse the aging process, you would want to do things that make you look and feel younger. The best and most obvious things to do to make your body look better is to exercise and eat healthy. These vitamins and minerals will help your skin and skin tone as well as the way you move. To get rid of wrinkles and old age spots, you will need to use a medical cream that is made to rid those unwanted items. Also, you can eat celery and smoothies to get rid of those problems around your eyes. There are certain foods and spices that get rid of wrinkles and sagging skin. These include pears, cabbage and turmeric. These have the vitamins that are needed to get rid of these things.

Overarching goal is to improve our ability to diagnose, treat and prevent cancer in racially/ethnicity (R/E) diverse and underserved populations Increase awareness/education about the importance of biospecimen collection among R/E and underserved populations Increase the collection of high-quality TCGA breast and prostate cancer specimens from R/E diverse and underserved populations

1. true-the state of theory in aging and the social sciences is made more complex by the fact that most work in the field does not deal with aging at all, but rather with age-related issues. (marshall, 1998:44).gerontology is essentially unreflective when it comes to examining the theories produced by some of its practioners. (katz, 1996).there is not enough qualitative and normitative data to adequately support theories of aging. as well, the role of lay or common sense theorizing within the lives of older persons is absent form most gerontological theory, as is the attempt to account for the aging experience through the use of narrative. (moody 1994:xv).

1. false-false. pathologic hypertrophy occurs as a result of disease conditions and may be adaptive or compensatory. examples of adaptive hypertrophy are the thickening of the urinary bladder from long-continued obstruction of urinary outflow and the myocardial hypertrophy that results from valvular heart disease or hypertension. compensatory hypertrophy is the enlargement of a remaining organ or tissue after a portion has been surgically removed or rendered inactive. for instance, if one kidney is removed, the remaining kidney enlarges to compensate for the loss (p. 31).

1. muscle tissue-disuse atrophy, particularly in muscle tissue, is related to workload. when confronted with a decrease in work demands or adverse environment conditions, most cells are able to revert to a smaller size and lower and more efficient level of functioning that is compatible with survival. as the workload of a cell diminishes, oxygen consumption and protein synthesis decreases. cells that are atrophied reduce their oxygen consumption and other cellular functions by decreasing the number and size of their organelles and other structures. an extreme example of disuse atrophy is seen in muscles of extremities that have been encased in plaster casts. because atrophy is adaptive and reversible, muscle size is restored after the cast is removed and muscle use is resumed (p. 30).
