What branch of biology deals with the nature of aging?

If you are talking about the actual aging process then it is gerontology. If you are talking about the treatment and prevention of disease in the elderly, then it is geriatrics.

For normally conceived animals, the biological age is the same as the chronological age. For clones, it is the chronological age of the clone plus the chronological age of the donor when the cell was extracted . If the donor animal was 5 years old when the cell was taken, then the clone's biological age will be its chronological age PLUS 5 years.\nhttp://www.messybeast.com/gene-jargon.htm\n\ncan be measured in terms of skeletal age, somatic (physique) maturity, or sexual maturation.\nhttp://www.gk22.com/resources/glossary.html

Biological or Physical age - How we view age by physical signs. Physical age is the by-product of DNA damage and repair deficit. Physical age is an indication that the body is breaking down. Physical aging can be described by graying hair, wrinkled skin, fragile body, hazy eyes. It is age of our bodies in regards to critical life signs. Different cells have different ages, since cells get replaced. Cells of the skin, the digestive track, read and white blood cells divide daily, the old ones being discarded. Other cells are replaced every few years. Nerve and muscle cells are our oldest components.

Avoid the sun. Vitamins A, C, and E. These are antioxidants. They prevent cell damage which significantly contributes to the aging process. Proper hydration is an absolute necessity to keep skin supple. Exercise and proper diet is also a huge plus.

That's a great question. There's a whole field called developmental biology that researches how organisms develop from single cells into complex organisms. The short answer is that different genes get turned on and turned off at the right times, and this causes cells to divide, move, differentiate (turn into different kinds of cells) and make connections with other cells. A lot of work has been done and a lot of work is still being done on figuring out exactly what the signals are that make this happen in an organized way.\n\nAn important reason that a lot of people work on this, in addition to understanding our world and ourselves better, is that the genes that work during development are often the genes that get messed up in cancer and other diseases. By understanding their normal role, we can better understand what happens when they aren't working right.

It isn't. As cells reproduce the DNA helix is unzipped and rezipped over and over. This causes the helix to unwind the more the helix unwinds the greater the rate of errors until the cell cannot survive. The reproductive life of the daughter cells becomes less and less. This process is called aging. The exception to this is in the sex cells as the dna from two "parents is combined to form new cells.

homeostasis is the underlying theme of all of nature and IMPLIES interdependence.  Most current anatomy-physiology textbooks FINALLY list how each system affects all the other systems of the body.  We use Tortora and Dickerson and the last page of each chapter itemizes all this.  Very helpful to teach the interconnectedness of the systems, yes, but also all of life-the cosmos.  It's all connected and interdependent from micro sub-atomic particles to macro galaxies and cosmos.

To keep it short, biology is life.  It's how we move, breathe, digest, and function.

biochemistry, science concerned chiefly with the chemistry of biological processes; it attempts to utilize the tools and concepts of chemistry, particularly organic and physical chemistry, for elucidation of the living system. The science has been variously referred to as physiological chemistry and as biological chemistry. Molecular biology, a term first used in 1950, is used to describe the area of research, closely related to and often overlapping biochemistry, conducted by biologists whose approach to and interest in biology are principally at the molecular level of organization. The related field of biophysics brings to biology the techniques and attitudes of the physicist. Cell biology is concerned with the organization and functioning of the individual cell and depends greatly on biochemical techniques. As the study of life forms demonstrated similar or even identical processes occurring in widely divergent species, it has taken the biochemist to unravel the underlying chemical basis for these phenomena. Biochemists study such things as the structures and physical properties of biological molecules, including the proteins, the carbohydrates, the lipids, and the nucleic acids; the mechanisms of enzyme action; the chemical regulation of metabolism; the molecular basis of genetic expression; the chemistry of vitamins; chemoluminescence; biological oxidation; and energy utilization in the cell. The study of the chemistry of the immune response offers the possibility of treatment and cure for such diseases as AIDS and lupus.

Hi Anita. I believe the best answer is D) histology.\n\nAnatomy is a much broader area than this.\nCell biology is more concerned with the internal functions of the cell.\nChemistry is not directly involved with how cells are arranged.\nPhysiology is a much broader area of study.\n\nHope this is helpful for you.  Best wishes.

People have a genetic coding that basically extends life to approx 125 years old.  Our genetic make up accounts for approximately 30% of our life expectancy.  Environment and habits accounts for the other 70%.  Our bodies are constantly breaking down and our body does not have the ability to repair these breakdown indefinately.  Once our body loses the ability to repair our breakdowns we begin to see signs of aging.  Once the process begins we are unable to effectively stop it.  Maybe with advances of science and gene therapy we can extend our ability to repair but until then you are kind of stuck with your genetic make up.

I suppose that two processes are to blame:\na) The accumulation of extracellular material (extracellular matrix)\nb) The accumulation of senescent (old, non-replicating) cells that are less able to maintain a stable environment\n\nThis is not an "official", research-quality response. I'm just talking out of my head but I think I may be right.

Ageing or aging is the process of getting older. Ageing is an important part of all human societies reflecting the biological changes that occur, but also reflecting cultural and societal conventions.Age is usually, but wholly arbitrarily, measured in years and a person's birthday is often an important event. \n\nand if you are interested scientifically how it happens, may following link help you.\n\nhttp://www.chem-tox.com/DNA/aging.htm\n\ncheers!!!

protein, DNA, almost every cell in every living organism...so, basically, all of life itself.

Quite a lot... see the links. Biology is the science of life, so as you can imagine, that subject has a wealth of sub-headings. It relates to chemistry, biochemistry, physiology, anatomy, botany, genetics,  and many other sciences.\n\nIt will depend on what level of biology course you are taking, but I've included a syllabus for some courses in the links.
