The correct answer is: John who has no genetic predisposition and goes dancing with his friends twice per week.
Alzheimer's disease is a neurodegenerative disease and the most common type of dementia. Patients suffering from this type of dementia exhibit problems with memory, cognition and behaviour. One of Alzheimer's risk factors is family history and genetic predisposition. Several genes have been found to increase the risk of developing Alzheimer's. Physical activity, such as regular dancing for example, stimulates the mind and can protect from dementia. Therefore, John is the least likely to develop Alzheimer's disease.
Answer:
The R organic group.
Explanation:
Amino acids are a complex of organic compounds that combine to build proteins. The general structure of an amino acid is set by a carboxyl group (―COOH), a basic amino group (―NH2), and an organic R group, unique in every amino acid.
The amino acids differ from each other in the <u>particular chemical structure </u>and organization of hydrogen, nitrogen, carbon and oxygen atoms present in the organic R group.
I would think the biological information passed from generation to generation is called “DNA”.
