Stroke may occurs at any age and strock risk increase with age
ANSWER: None of the above options are correct.
Cardiac Output(CO) = Stroke Volume(SV) × Heart Rate(HR)
Therefore where HR= 90bpm and SV= 110ml/min,
CO = 90 × 110 = 9900ml/min or 9.9L/min.
EXPLANATION:
CARDIAC OUTPUT is the volume of blood being pumped by the heart into the systemic circulation per minute.
Cardiac output is the product of two variables, stroke volume and heart rate.
STROKE VOLUME is the amount of blood pumped out by the left ventricle in each contraction.
HEART RATE is the count of the number of times the heart beats per minute.
Can spread themselves more easily and reproduce more while not staying in the same spot.
Oxygen entered the Earth's atmosphere after the appearance of the Great Oxidation Event (Great Oxygenation Event). The Great Oxidation is the first mass extinction on Earth.
The Great Oxidation lasted 2.4 to 2.0 billion years ago.
Oxygen appeared on Earth thanks to cyanobacteria using photosynthesis.
Not sure if this is multiple choice but this is what I say.
