Bone remodeling is a lifelong process where old bone is removed and new bone is formed. By studying the pattern of bone remodeling in skeletal remains, such as the amount of mineralization and presence of growth plates, forensic anthropologists can estimate the age of an individual at the time of death. Changes in bone density and structure can provide valuable clues for determining age.

What isotope is used to determine age of bone?
Carbon-14 is the isotope commonly used to determine the age of bones and other organic material. This radioactive isotope is incorporated into living organisms and decays at a known rate, allowing scientists to estimate the age of the bone based on the amount of carbon-14 remaining.
What method is used to find the age of a bone fragment?
radioactive dating, usually using the carbon-14 method, but this method can't be used for bones more than 50 or 60 thousand years old. -hope this helps. our teacher just taught us this today in 8th grade, its pretty hard so good luck.
How does a coroner determine the age?
A coroner can determine the age of a deceased person through a variety of methods, including examining growth plates in bones, analyzing dental records, and assessing the overall condition of the body to estimate age based on factors like bone density and wear. DNA testing can also provide more accurate age estimates in some cases.
Can carbon dating tell how old the person is?
No, carbon dating cannot determine the age of a living person. Carbon dating is used to determine the age of organic materials such as fossils or artifacts by measuring the decay of carbon isotopes. It is not used for dating the age of living organisms.
What method do geologists to determine the absolute age of a rock?
Radioactive dating is used to determine the absolute ages of rocks. By Jennifer Palos
How can bone remodeling determine age?
Bone remodeling can provide information about someone's age through the process of continuous bone turnover. As people age, their bones undergo remodeling, where old bone is broken down and new bone is formed. By studying the rate of bone remodeling and the balance between bone formation and resorption, researchers can infer an individual's age. Additionally, changes in bone density, structure, and composition can also indicate age-related bone remodeling patterns.
How can bones determine age?
Bone remodeling can help determine age because when a person is dead their bones shows every little mark , which on most bones displays a pattern called lamellar.
How do bones grow and what does remodeling mean?
Bones grow through a process called ossification, where new bone tissue is added to existing bone. Remodeling refers to the continuous process of breaking down and rebuilding bone tissue to maintain its strength and structure. This process is regulated by specialized cells called osteoclasts and osteoblasts.
What is the universal loss of bone mass seen in the skeleton which begins about the age of 40?
Osteopenia is the universal loss of bone mass that begins around age 40. It is a milder form of bone loss than osteoporosis and can increase the risk of fractures. To help prevent or slow down osteopenia, it is important to maintain a healthy diet, exercise regularly, and ensure an adequate intake of calcium and vitamin D.
Is it human method for bone age can apply to animal bone?
The human method for estimating bone age is not directly applicable to animals due to differences in skeletal development and growth patterns. Animals have unique processes of bone development that may not align with human standards. Specialized methods and markers specific to the species of animal in question should be used to determine bone age accurately.
What isotope is used to determine age of bone?
Carbon-14 is the isotope commonly used to determine the age of bones and other organic material. This radioactive isotope is incorporated into living organisms and decays at a known rate, allowing scientists to estimate the age of the bone based on the amount of carbon-14 remaining.
Why do peoples bones stop growing at the age of 20?
Bone growth is controlled by a variety of factors, including growth plates found at the ends of long bones. At around age 20, these growth plates ossify and turn into solid bone, which signals the end of longitudinal bone growth. After this point, bone remodeling and maintenance occur instead of growth.
What was the use of bone hook in stone age?
In the Stone age, bone hooks were used for fishing.
Which element is used for archaeological discoveries?
Carbon-14 dating is commonly used in archaeology to determine the age of organic materials, such as bone and charcoal. This method measures the radioactive decay of carbon-14 isotopes in the sample to estimate its age.
Relative dating is used to determine the?
Relative age is used to determine the age and how old a geological feature or fossil.
Is there a difference between stone age bone flute and stone age stone flute?
Yes, bone flutes are made of BONE, and stone flutes are made of STONE. They were both used during the Stone Age
How do scientists determine the age of a fossilized human bone?
The teeth: wear and tear - How much grinding has occurred? The presense of wisdom teeth indidcates certain ages. Also the sutures of the skull close at various ages.
