Aging, it’s something that as a species of life on this planet we are predisposed to and its results are an inevitable factor that effects our bodies in several ways, from cataracts development to the progression of memory issues from such diseases as Alzheimer’s or Huntington’s. The concepts of aging are broken down into two theories widely accepted by several varying fields of studies such as gerontology, the study of the aging process, and oncology, the study of cancer and tumor development.
mechanisms such as natural selection or genetic drift. Charles Darwin came up with the theory of natural selection. Darwin believed that living organisms tended to survive and produce more offspring when they were better adapted to their environment. Apart from natural selection, genetic drift was also an important mechanism. Genetic drift occurs when the gene variant changes due to the random testing of organisms. Populations of organisms change over time because of natural selection and genetic drift. The
When a person thinks of aging, they can think of many things, from a baby getting taller, to an older person growing gray hair. A person’s body changes constantly throughout the span of their life. There is no helping it. While most people think of a person getting older as a person getting wrinkles, losing hair, and becoming more fragile, there are actually many other affects than just those. There are visible effects, and effects that are not visible by just looking at someone. In this paper, both
over time. The changes include physical, social and psychological changes. Causes of aging are very uncertain. Besides, there are several factors which predispose an individual to premature aging. Current theories suggest that this process occurs to due to cellular damage such as DNA oxidation by free radicals causing biological systems to fail. Internal processes such as DNA methylation may also result in aging. Predisposing factors such as space escapades, use of chemically intoxicated substances
What is aging? It is not easy to come up with a working definition of aging; different academics around the world defined ‘aging’ from different perspectives. Based on the collected information I have, I define aging –a multidimensional process of physiological, mental and social changes that occurred over the course of life. Though it is beyond human control, aging experiences may vary between individuals. “In the developed world, chronological time plays a paramount role. The age of 60 or 65, roughly
Gabrielle Cardina AGNG 200 9 October 2014 Midterm Question 1) Aging is a natural and inevitable feat that every living organism must muster. Although we accept that aging, no matter the rate, happens, some cannot do so without reason nor a formal explanation. Because of these people, there are theories and ideas that were made up to capture the full frame of growing older. I believe that the act of aging can be perceived in two different ways: physically or mentally. These are two completely
Aging is a process through which organism’s functionality decline systematically. The decrease in human organism is due to genetic cellular and molecular modifications. The level of changes on the longevity of the plant can affect it in several ways in a gradual process as the age progresses with time. According to Finch, the process of aging can also have a definition that it is the accumulation of underlying molecular errors (Finch,2007). These errors with time eventually corrupt the adult stem
Aging and genetics play a role in developing a cognitive disease known as Alzheimer’s, but why do some people get it and some don’t? According to the Centers for Disease Control, more than five million Americans are living with Alzheimer’s disease today. Research shows that by 2050 there could be as many as 14 million people with the disease. About 350,000 new cases of Alzheimer’s are diagnosed every year in the US. It is the 4th leading cause of death in adults after heart disease, stroke, and
Genetic Engineering: The Science of Replacing Natural Selection and Evolution Consider the implications of the following: tomatoes are sensitive to frost, which shortens their growing seasons. Fish, in contrast, survive in very cold water. Scientists have found the specific gene that enables fish to resist cold in a flounder, and used genetic engineering to incorporate it into the genetic material of a tomato. By what moral authority does science have the right to make this transformation?
As aging is a stage of development that cannot prevented, the question of “can one’s aging be more successful than another?” is posed my many. Researchers continually consider the differences between aging successfully, and aging unsuccessfully. As researchers work to complete their studies, many find a reoccurring basis of successful aging. A basis of successful aging can be set including: physical health disease free, chronic illness free, mental health disease free, among many others. The
