Answer
3× 105 kg in the calculation represents the mass of the space shuttle.
Explanation
When calculating the force of gravity of on the shuttle, the formula used is ; force of gravity=mg. m represents the mass of the object(shuttle) and g is the acceleration of the shuttle due to gravity. g= 9.81 m/s².Multiplying the mass of the shuttle by 9.8 gives the force of gravity

A mutation is a change in a DNA sequence brought about either by a mistake made when the DNA is copied or through chemical damage. Regions of the genome (called genes) provide instructions for creation of protein molecules, which perform most of the important jobs in cells. Certain types of mutations are silent and have no effect, but others affect protein production in a variety of ways.
