Ratling [72]

Answer:

B. very high genetic variation

Explanation:

Selective breeding is the process by which crops or animals with desired phenotypic traits are chosen to produce offspring, which will contain the desired qualities. In this case, a group of scientists is trying to apply the principles of selective breeding to develop a particular crop plant.

This goal of producing a useful crop plant by the scientists can only be achieved when the plant species in question possess a HIGH GENETIC VARIATION i.e. difference in genetic constitution of individuals of the same species. This allows the individuals in the population to survive better.

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.
