Answer:
4875/12927.
Explanation:
The cardiac output may be defined as the product of the heart rate and the stroke volume.
Cardiac output= stroke volume ×heart rate
The cardiac output at rest can be calculated as follows:
The stroke volume at rest is 75 and the heart rate is 65.
Cardiac output = 75×65
Cardiac output = 4875
.
The cardiac output after exercise can be calculated as follows:
The stroke volume has been increased by 24%.
Final stroke volume = 75 × 24/100 + 75
Final stroke volume = 93.
Heart rate = 139.
Cardiac output = 139×93
Cardiac output = 12927
.
Thus, the answer is 4875/12927.
The guidelines for making good and accurate observations are:
1. Standardise the experimental setup: Know the precision and the accuracy of the instrument used to make observations. Example, thermometer with a least count of 1°C cannot measure in fractional values.
2.Take careful measurements: Holding the instrument properly without causing any disturbance is the key.
The horned lizard can confuse a predator by shooting blood from it's eyes, with control over the height (up to 5ft) and the direction of the blood.
Carbon is released back into the atmosphere when organisms die, volcanoes erupt, fires blaze, fossil fuels are burned, and through a variety of other mechanisms.
