Question 1:
A) Dr. Leon dePonce’s hypothesis for his study is that prune juice has an effect on aging.
B) The experimental group was the laboratory mice that had received prune juice in their diets and the control group was the mice whose diets stayed the same, with standard mice chow and tap water.
C) The hypothesis is rejected because the results were that the life span stayed the same with both groups, indicating that prune juice had no affects on age.

Question 2:
A) Aging is an inevitable process humans undergo; it is a series of changes the body goes through as it develops to its full potential and then begins to degrade. The process of aging can more biologically be thought of as the build up of cells to peak function…show more content… One organ system is the lungs, which lose the elasticity in their tissue. This causes the amount of air intake inhaled to decrease and can lead to breathing issues. Breathing issues in turn affect the loss of oxygen could lead to blood cell issues, which affect other bodily functions and organs like the heart. The heart becomes weak if not pumping to usual speed and fatty deposits could get accumulated in the arteries. Another organ that changes is the gut, which loses its digestive enzyme functions, affecting your nutritional balance (1). All of these organ defects are at the fault cell changes, which occur at various rates and extents in each individual. One common change that could directly affect these organs is the increase in cellular aging or senescence, an article describing cell aging refers to two scientist, Hayflick and Moorhead who first studied the phenomena, “They showed that human cells in culture do not divide indefinitely but reach a limit (called the Hayflick limit) of replication and stop all further division. Cells approach this limit by slowing their divisions and entering cellular senescence, a dormant period” (2). Senescence and apoptosis, cellular suicide, are common in the body but with age they occur too often or are suppressed from happening at all. The cells in our body constantly receive signals and give off signals so like a chain reaction when one halts the process of signal transmission then the rest of the cells associated with the function of that cell will be affected and errors will occur. These errors affect various organs as mentioned
