Brut [27]

<u>Answer:</u>

Q: Which skeletal system <u>disorder</u> might she be suffering from?

A: <u>Osteoporosis</u>

Q: What <u>techniques</u> could be used to diagnose her condition?

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

Q: What treatments are available?

A: Medication, healthy food.

<u>Explanation:</u>

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

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

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

Tcecarenko [31]

In the plant, when a cell divides into two daughter cells, we observe in this experiment Mitosis, which is the cell division that allows the plant to elongate and occurs in the meristematic tissues that are at the ends of the plants. Whereas meiosis is restricted to reproductive tissue and forms gametes that will form new seeds through fertilization, carrying genes from one generation to another.

<h3>How does mitosis occur in plant cells?</h3>

In plant cells, division takes place from the inside out – centripetal cytokinesis. In plant cells, cytokinesis is centrifugal, from the outside to the inside: there is the formation of a lamella, which grows from the center to the periphery and separates the two cells.

With this information, we can conclude that through successive mitotic divisions that the zygote (cell generated after the meeting of gametes) manages to originate all the cells of its organism. Mitosis, therefore, is responsible for the growth and development of embryos.
