Staining is done for onion cells to visualize the cytoplasm of yellow and white onions because they are not pigmented. The staining of human cheek cells with methylene blue is necessary to stain the nucleus to get clear image of it under microscope because methylene blue binds to negative charge nucleic acids
While for leaf epidermal cells smears, staining is not necessary as they are visible under light microscope without staining and they also have pigmented materials inside them such as chlorophyll chloroplast. The cork cell is a non-living and have a cell wall whose structure is visible under light microscope.
Hypertension is most commonly known as high blood pressure, which is condition where the blood in a persons arteries are abnormally high. high blood pressure/hypertension can be lowered by maintaining a healthy lifestyle. this means that you must exercise regularly and eat well, which tells us that option B and D are incorrect. hypertension is also known to cause heart attacks if it is left untreated for long periods of time and can occur if you are being treated for heart disease, but heart disease is usually never the cause of hypertension. since we have determined that option C is also incorrect,, we a left with option A as the correct answer to this question. having hypertension can be genetic, so if you have two parents who are genetically prone to this condition you are more likely to have it.
