41) option b -10C
42) option e-26,000 years
43 ) option d- all of A, B and C
Milankovitch cycle includes three cycles related to earth's precession,axial tilt and eccentricity.
44) option d- it is DNA that is responsible for heridity.
hershey chase experiment proves that DNA is the genetic material
