Answer:

questions:

Should I or can I eat salty foods?

Do I have to check my pressure immediately?

Do I have to follow a balanced diet?

Is it good to do physical activity?

Do I have to worry about the signs of eye flickering and headache?

Explanation:

Blood pressure is regulated by endogenous mechanisms, although these sometimes fail and it is necessary to take drugs to reduce high blood pressure, an example of which is beta-blockers.

Blood pressure is also regulated by diets based on low sodium consumption, necessary calories and with great contributions of nutrients since cardiac or cardiovascular health is also essential in the face of possible formation of atheroma plaques.

The increase in blood pressure with the appearance of atheroma plaques is very common, and it is also the two most frequent causes of AMI (acute myocardial infarction)

Answer:

The stratosphere

contains the ozone layer ,

is used by airplanes,

has strong, steady winds , and

increases in temperature as altitude increases .

Explanation:

The stratosphere is the atmospheric layer between 10 km and 50 km above the Earth's surface.

It includes the ozone layer, which is at an altitude of about 20 km.

It has strong, steady winds that can reach as high as 220 km/h.

Passenger aircraft generally fly in the lower levels of the stratosphere, at altitudes of about 10 km to 12 km.

Temperatures increase with altitude, from -50 °C at 10 km to -3 °C at 50 km.

A is wrong. The mesosphere (altitude 50 km to 85 km) is the coldest of the atmospheric layers, with temperatures as low as -90 °C at 85 km.
