Answer:
A heart attack occurs when the flow of blood that carries oxygen to the heart is blocked. The myocardium is deprived of oxygen and begins to die.
A person who has a heart attack may have some of these symptoms, or all of them:
Uncomfortable pressure, inflammation or oppressive pain in the center of the chest
Discomfort or pain that spreads beyond the chest to the shoulders, back, neck, jaw, teeth, one or both arms, and sometimes the upper abdomen
Shortness of breath
Stun, dizziness and fainting
Sweating
Sickness
Usually, a heart attack causes chest pain for more than 15 minutes, but it also may not show any symptoms. It is important to know that other symptoms may occur in addition to chest pain, such as indigestion or persistent pain in the neck or jaw.
Many people who have a heart attack have warning signs in advance of hours, days or weeks.
The correct answer is C.
Explanation
According to the information provided, a bar graph (option C) is needed since this type of graph allows us to express the variation in time, distance, temperature, quantities, weight, among others. In this specific case, a bar graph allows students to analyze the time that each type of seed takes to fall from the second floor. Additionally, this is the only graph that shows the data of the chart. For example, the first bar represents the black walnut and its time is 0,6 seconds, and this value is shown by the light blue bar in the graph, which represent the same seed. According to the above, the correct answer is C.
