Answer:white blood cells?
Explanation: It could possibly be them, since they fight infections
Originally, there were only five bacterial cells. After one month, the amount of bacteria is doubled with ten bacteria. The growth is represented by the formula:
a42 = 5 x 2^1
After 42 months, the growth can be solved using this formula:
a42 = 5 x 2^42
Answer : The correct answer for cardiac output is 18 Liter per minute
Cardiac output is the amount of blood pumped by heart per minute. It is product of heart rate and stroke volume . Heart rate is number of beats per minute (bpm) and stroke volume is volume of blood pumped per beat (Liter per beat or Lpb) . Cardiac output can be calculates using following formula :
Cardiac output = Heart rate ( HR ) x stroke volume (SV )
The unit of cardiac output = Liters per minute
Given : Heart rate = 150 bpm
Stroke volume = 120 mL
Since volume is in mL , this need to be converted to L.
Plugging values of HR and SV in formula :
Cardiac output =
Cardiac output =
With the Algae becoming multicellular, it was made possible for them to develop traits that
keep them close to the land and thus close a source of nutrients .
