b) identify the enzymes outside the

c) determine the size of vanous organelle
d) separate the major organelles so that their
particular functions can be determined
e) crack the cell wall so the cytoplasmi
contents can be released.

tropopause, stratopause and mesopause have all in common aspect that is point of maximum temperature in its layer of the atmosphere. all layers of atmosphere observe abrupt change in temperature. tropopause is the boundary between troposphere and stratosphere. stratopause is the boundary between stratosphere and mesosphere. mesopause is the boundary between mesosphere and thermosphere. these all boundaries are ranges between altitude of 0 to 80 km.
