Explanation:

Mitosis is the nuclear division followed by cytokinesis, which leads to the production of two daughter cells.

<u>It includes the following phases - </u>

1. Interphase - In this process the Cell actively metabolizes and prepare itself for the process of mitosis and the Chromosomes are not clearly discerned .

2. Prophase - In this phase , the Chromatin gets to condense and can be visualized under a light microscope and  Nucleolus gets disappeared , Centrioles begins to move to opposite ends of the cell .

3. Metaphase - In this phase the Spindle fibers gets align the chromosome along the middle of the nucleus of the cell thereby creating a metaphase plate .

4. Anaphase - In this phase , the chromosomes which got paired up gets separate at the kinetochores and move to the opposite directions of the cell , the Spindle microtubules and physical interaction among polar microtubules is responsible for kinetochore movement.

5. Telophase - In this phase , the Chromatids completely move to the opposite poles of the cell , and new membranes start forming around the daughter nuclei and the Chromosomes disperse and become invisible. Cytokinesis starts.

6. Cytokinesis - In this final process the Actin fiber ring around the center of the cell contracts and create the cell into two daughter cells.

andriy [413]

Osteoporosis is a bone disorder that affects the structure of the bones and their hardness. The risk factor for Osteoporosis can be avoided by intaking a diet rich in calcium and vitamin D.

<h3>What is Osteoporosis?</h3>

Osteoporosis is the disease of the skeletal system that weakens the bones and makes them susceptible to breaking by becoming brittle. The bones in the diseases become very fragile that even a small stress condition can lead to bone fracture.

As one ages the level of calcium and vitamin D produced in the body gets depleted and as a result, the bones become weak and porous. The level of these elements must be balanced by the external food in the diet.

The nurse should provide information to the older adults on Osteoporosis by educating them on the dietary intakes that are rich in vitamin D and calcium. The intake of sodas must be reduced as they are rich in phosphorous that weakens the bones.

Therefore, dietary information must be given to the person to reduce the chances of Osteoporosis.
