The heart’s electrical system is responsible for making and conducting signals that trigger the heart to beat. These signals cause the heart’s muscle to contract. With each contraction, blood is pumped throughout the body. This happens 24/7 without us having to monitor it all the time so that our heart does not stop.
<u>Answer</u>:
A scientist is most likely to use a simulation in a controlled experiment in order to observe a 1000-year process in one day.
<u>Explanation:</u>
In scientific observation, its carried out in the control environment so as to minimise the effects of the variables besides those independent variable, which also helps in increasing the accuracy of the results. also frequently through comparison between those control environment and other measurements. Through this process data of 1000 years can be studied in very short period of time. And also getting the accurate details. This is also known to be doing multiple experiments at certain period of time.
The surface area of a sphere is given by the expression, . The volume of the sphere is given by the expression, .
Dividing the surface area expression by the volume expression, we get, .
So the ratio is inversely dependent on the value of r.
Given for the sphere, the surface area = 588 m², and the volume = 1372 m³.
Dividing the surface are by volume, we get, as the answer.
One is immune system.
