Answer:
The finding is expected. This is due to older people having a very depleted amount of proteins and calcium which affects their bone density.
Aged people have a large amount of osteoclasts which is responsible for the the breakdown of bone for repairs and remodification which poses a great risk for decreased and weakened bones.
The 9 yr old grand daughter however has large amounts of osteoblasts which help in bone production and translates to stronger bones.
This features and findings are the assumed and likely reasons why the 75yr old woman had fractures and the 9 yr old grand daughter suffered none.
The answer is D proteins. viruses<span> contain nucleic acid, either DNA or RNA and a protein coat</span>
Genetic engineering is important to the scientific community because A)
Genetic engineering provides crops that are less expensive to grow. One
of the biggest problems that the world may face in the near future is a
food supply shortage due to the increasing exponential growth of the
population. Genetic engineering provides crops that are more hearty,
larger and less expensive to grow that may be the answer to mounting
future problems. The ability to manipulate plants in the lab makes
altering their growth pattern a much faster change than many years of
natural selection in the farm and field.
DNA<span> replicates </span>before<span> a cell divides to give a complete set of genetic instructions to each daughter cell. Semiconservative </span>replication<span> means that only one strand of </span>DNA <span>molecule is newly formed. The other stand is original </span>DNA<span> from the parent cell.</span>
