Answer:

The most frequently damaged tissues are the skin and mucosa, which causes the body to activate a repair process consisting of the following steps:

1- Inflammation: This process involves the cells of the immune system, white blood cells, antibodies, lymphatics. All these cells work together, once the vessels expand, they act producing an inflammation process where coinside these cells eliminating necrotic tissue, bleeding and coagulation is formed.

2- Organization: In this step, the clot begins to form in granulation tissue that is a tissue composed of several elements and that goes from the central part of the lesion to the periphery. In this stage new capillaries grow, fibrolastic tissues are formed that produce growth factors and collagen fibers.

3- Regeneration: A superficial epithelial tissue begins to grow under the granulation tissue. As the underlying fibrous tissue matures and becomes fibrous until it finally resembles the adjacent skin. Finally forming a fully regenerated epithelium.

What are the phases of mitosis and what happens in each?
xxMikexx [17]

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.

yanalaym [24]

Answer:

Traditionalists: Adherence to rules, discipline, family focus, hard work, and trust in the government.

Baby Boomers: Anti-war, anti-government, equal rights, involvement, and personal gratification.

The way that one generation passes on its values to the next usually reflects the same philosophy and attitudes as the transfer of wealth. For example, someone who passes on the value of compassion and service will likely also pass on assets to charity.

A mother brought her four-year-old daughter to the doctor, complaining that her daughter didn't "look right." The child's forehe
lozanna [386]

Answer:

Rickets disease.

Explanation:

Rickets disease occurs when there is a mineralization deficit of the extracellular bone matrix; as a result, the bones are soft, and they deform easily. The X-rays show thick epiphyseal plates because it is hyaline cartilage that should be calcified to become a bone. As there is a deficit of vitamin D, the mineralization of the plate can not be done, making bone is flexible and deformable.

The main cause for Rickets disease is a diet with low intakes of calcium and vitamin D, and poor exposition to the sun, which is the best way to produce vitamin D. These two components are crucial for the mineralization of the bones.
