Answer:
Cardiac output = 20 L/min
Explanation:
The cardiac output of a person refers to the volume of blood the heart pumps in a minute. The normal range for cardiac output is about 4 to 8 L/min. However, this can vary depending on the metabolic needs of the individual at any instant of time, for example, it is higher when exercising than when resting.
Cardiac output is calculated from the product of the stroke volume in liters/min and the heart rate in beats/min
Cardiac output = stroke volume * heart rate
For the individual who is running; stroke volume = 100 mL/beat or 0.1 L/beat
heart rate = 200 beats/min
Cardiac output =0.1 L/beat * 200 beats/min
Cardiac output = 20 L/min
cancer cells are harmful to living things and can produce cancer.
Answer:
Option (1).
Explanation:
Dual x-ray absorptiometry technique is used for the evaluation of the bone mineral density. The bone densitometry is normally used in this technique to estimate the mineral content of bone.
The radiation dose in the absorptiometry is considerable and only small or low amount of radiation dose is considered. The heavy dose may cause health problems in the individual. The photon energies are used for the bone and soft tissue. The treatment of osteoporesis can be done by this technique.
Thus, the correct answer is option (1).
Due to the fact that they can mutate, they can adjust to many situations. If their environment changes and becomes colder for example, many other things will die but a virus can change to adapt to their new climate.
