Chapter 3.11, Problem 78AYP
Summary Introduction
To determine:
The five hypotheses that explain the process of aging.
Introduction:
The cell division and cell death work collaboratively to maintain the normal physiological functioning of a multicellular organism. The cell division works to increase the number and size of cells for different organs and tissues. However, cell death eliminates the cells that are old or do not possess normal cell functioning. The cell division and cell death are highly regulated and dependent on several key enzymes and protein complexes.

An individual with the disease usually does not manifest symptoms until he or she is between 30 and 45 years of age. The disease then progresses to death over the next 10 to 15 years. If a child of an affected parent has not developed symptoms by the age of 45, it is not likely that the symptoms will ever develop. Discuss your thinking process when deciding whether you would or would not choose to have the testing to know if you will develop Huntington chorea.arrow_forward
- How does evolution contribute to aging?arrow_forwardWhen the body is in a state of "dis-ease" the systems in our body do not function the way that they do when we are in a state of "ease". In a study of two adult twin sisters age 54, Beth and Mary, scientists were trying to understand why these twins had very different body weights and why Mary was suffering from a gastrointestinal disease yet her sister was healthy. They studied the healthy twin (Beth) to see if they could learn anything about her sisters disease from studying her. They were raised in the same house until they went to different colleges (Beth stayed in London and Mary lived along the coast line in a farm town in France). They were both mostly healthy throughout their childhood although Mary had a very sensitive stomach and suffered from allergies. Through the use of questionarres, stool samples and genetic samples the researchers learned so much about the two sisters, including that Beth was born vaginally but Mary was born by C- section because their mom was to…arrow_forwardWhat does research suggest about regular physical activity's effect on the life span? A. Consuming a healthful diet while engaging in regular physical activity can reduce oxidative stress without the need for Calories B. People genetically predisposed toward a lean body type live longer even if they eat poorly and fail to engage in regular physical activity C. Excercise increases the risk for osteoporosis and fractures, reducing life span D. To prolong life span, physical activity must be performed at least four times a week in sessions lasting at least 45 minutesarrow_forward
