PLZ HELP!!! 50 POINTS!!
Dmitrij [34]
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.
let me know if you have any further questions

arsen [322]

Answer: To know if a document is a primary source, check to see when the document is published, if it is an autobiography of a person, a diary, a letter, or the documents happen at the time of the event.

The competition between two organisms can be seen if there is only 1 source of food or habitat space and they're competing against each other for the food or habitat.

There is cooperation between two organisms if they are helping each other with resources or alarming each other if there is danger.

Predation between two organisms happen when one organism hunts the other organism for food.
