Vedclass · Answer

(A) Senescence,or old age,is characterized by the end of the reproductive phase in an organism's life cycle.During the final stage of the life span,concomitant changes occur in the body,such as a slowing down of metabolism,which eventually leads to death.In both plants and animals,hormones are responsible for the transitions between the three phases of life (juvenile,reproductive,and senescent).The interaction between hormones and certain environmental factors regulates the reproductive processes and governs the behavioral expressions of organisms.
