Interesting question. Consider the formula that governs the gravitational formula
F = G * m1 * m2 / r^2
G is the gravitational constant. It does not change no matter where you are in the inverse, nor is it found to be different under normal circumstances. Since you have asked this in biology, you can assume that the circumstances are always normal./
m1 and m2 are masses in kg. The mass is invariant as well anywhere in the universe, except perhaps near or in a black hole.
r^2 is a distance in meters.
So the Force of gravity (in Newtons) varies directly as the masses involved and inversely as the distance squared.
Explanation: oxygen poor blood from the right ventricle into the lungs, where the oxygen enters the bloodstream. The pulmonary veins bring oxygen rich blood to the left atrium.
This is 21st century .In this time our society as well as all of the world had become advanced and modern.So,in this time if we started to work without any technology then while working we need more manpower and our time will be loss.Science ,technology,engineering and maths play important role in modern world d .It helps in sustain able development and helps any country to be self dependent and makes profit by which Nations will be developed and it helps to win the future.
