Answer:
c. The abnormality is in the thyroid gland itself.
Explanation:
Primary hypothyroidism arises from a pathology in the thyroid gland itself and occurs when the thyroid gland is not able to perform one of its many physiology. Secondary hypothyroidism starts at the level of the pituitary gland and results from under secretion of TSH. TSH is needed to trigger the release of the T3 and T4 stored in the thyroid gland. Tertiary hypothyroidism is caused by a decrease level of the TRH from the hypothalamus. This reduced level, in turn, reduces TSH and thyroid hormone levels in the blood, hence in the body and the patient suffer the symptoms.
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.
Explanation:
The difference is - standard precautions are gloves, mask,
additional precautions are for someone with MRSA, or very infectious diseases, add a grown, shoe covers, thicker mask etc.....
Answer:
a risk factor is a variable that increases your risk for a disease.
ex. being a smoker is a risk factor for lung cancer.
