Answer:

MEANING

A heart attack is a medical emergency. A heart attack usually occurs when a blood clot blocks blood flow to the heart. Without blood, tissue loses oxygen and dies.

A heart attack occurs when one or more of your coronary arteries become blocked. Over time, a coronary artery can narrow from the buildup of various substances, including cholesterol (atherosclerosis). This condition, known as coronary artery disease, causes most heart attacks.

CAUSES:

Chest Pain, Pressure, Fullness, or Discomfort.

Discomfort in other areas of your body.

Difficulty breathing and dizziness.

Nausea and cold sweats.

FinnZ [79.3K]

This type of passive transportation is called OSMOSIS.
Osmosis is a type of passive transportation in which a liquid moves from the region of high concentration to the region of low concentration. The movement usually continues until the amount of liquid on both sides are the same. This type of movement does not require energy because the flow is naturally favored, that is, molecules moves from high end to low end.

What characterizes depolarization, the first phase of the action potential? The membrane potential changes to a less negative (b

svp [43]

Answer:

Option (2).

Explanation:

The cell potential or membrane potential may be defined as the difference in the electric potential between inside and outside of the cell. The membrane potential of the cell changes during the propagation of action potential.

The resting membrane potential is -70mV. The influx of sodium ions causes the depolarization of the cell membrane. The cell potential changes from -70mV to + 30mV. The membrane potential becomes more positive during the depolarization phase.

Thus, the correct answer is option (2).
