What term is used to identify when a cell is temporarily deprived of blood supply
Infarction
Ischemia
Necrosis
Inflammation
The Correct Answer is B
Ischemia refers to the temporary deprivation of blood supply to a particular tissue or organ, resulting in reduced oxygen and nutrient delivery to cells. This can lead to cellular injury and, if prolonged, irreversible damage. Infarction, on the other hand, refers to the death of tissue due to prolonged ischemia. Necrosis is a type of cell death that occurs when cells are damaged or injured and cannot survive. Inflammation is the body's response to tissue injury or infection, and can be a result of ischemia or necrosis.

Correct Answer is A
Explanation
Primary hypertension, also known as essential hypertension, refers to high blood pressure that has no identifiable underlying cause. Risk factors for developing primary hypertension include a family history of hypertension, age, obesity, smoking, sedentary lifestyle, stress, and certain dietary factors.
Specifically, diabetes mellitus is a risk factor for hypertension due to the effects of insulin resistance and hyperinsulinemia on the blood vessels, as well as the increased prevalence of obesity and other comorbidities. Moderate alcohol consumption (up to 1 drink per day for women and up to 2 drinks per day for men) may actually have a protective effect against hypertension, but excessive alcohol intake can raise blood pressure and contribute to the development of hypertension.
Asian race is not a significant risk factor for primary hypertension, although there may be differences in the prevalence and severity of hypertension among different racial and ethnic groups.
