Chromosome is a structure that contains DNA molecules packaged around histone proteins, therefore carries the heredity material. Chromosomes number determines whether a cell is haploid (n) or diploid (n). A diploid cell has both set of homologous chromosomes while the haploid cell has only one set. Nucleus is the cellular structure that is responsible for the localized storage of chromosomal DNA.

The geosphere has four subsystems called the lithosphere, hydrosphere, cryosphere, and atmosphere. Because these subsystems interact with each other and the biosphere, they work together to influence the climate, trigger geological processes, and affect life all over the Earth.

Answer:
The correct answer is cells can do more in less time.
Explanation:
Human body has developed specialized cell so that specific cells can carry out specific functions of the complex human body system.
       Each body cells are specialized for their specific function for example heart cells act as pump,lung cells helps in gas exchange,blood cells helps in transport of biomolecules,muscle cells helps in the contraction and relaxation.
   Thus the numerous functions of human body are divided among specific cell so that each cell will have low work load and can carry out their specific functions in less time.
