I think the most critical consequence of the advancement of the amniotic egg it the tetrapods were no longer attached to the water for reproduction.The amniotic egg permits reptiles, flying creatures, and warm-blooded creatures to lay eggs ashore without drying out. The liquid filled depression containing the incipient organism is isolated from the outer condition by an amniotic sac that is impermeable to water.

Antibody staining can be visualized with either fluorescent or radioactive labels. Antibody staining can be performed by western blotting method.Multiple antibodies can be used to stain different proteins.Antibody staining requires the hybridization of the complementary base sequence of the antibody and also the target protein to which it binds.

Brut [27]

Answer:

Q: Which skeletal system disorder might she be suffering from?

A: Osteoporosis

Q: What techniques could be used to diagnose her condition?

A: Bone mineral density (BMD) test or dual energy X-ray absorptiometry (DXA) scan

Q: What treatments are available?

A: Medication, healthy food.

Explanation:

The vertebral discs between vertebrae could shrink with age. Therefore, a height loss up to 1-inch is normal. However, if the height loss is more then it is possibly due to osteoporosis.

A bone mineral density test, also known as dual energy X-ray absorptiometry scan, is a well-adapted test to measure the amount of calcium and other minerals in the bones. It uses X-rays to measure the content of calcium and thus strength of bones.

A person who is already suffering from osteoporosis should be treated with medicine right away so that it stops further deterioration of the bones and avoid any future bone fractures. Further, it can be handled by eating a healthy diet and supplements such as vitamins D. In case some of the bones/vertebrae are already fractured, surgical approaches might be necessary.
