In the early 1900s, scientists noted that chromosome movements during cell division in reproductive cells mirrored the patterns of inheritance described by Mendel. These results and others confirmed that Mendel's hereditary units (genes) were located on chromosomes. The sum total of chromosomes in an organism and the alleles they carry constitute its , whereas the organism's observable traits constitute its . See Section 1.1

the answer to you question is   jet streams

explanation:

the universal gravitation equation. since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. if the mass of one of the objects is doubled, then the force of gravity between them is doubled.
