Is Earths global mean temperature changing? explain your answer the words TREND and FLUCTUATION.
beks73 [17]

Answer:

Yes the Earths golbal mean temperature is changing.

Explanation:

The global temperature record represents an average over the entire surface of the planet. The temperatures we experience locally and in short periods can fluctuate significantly due to predictable cyclical events (night and day, summer and winter) and hard-to-predict wind and precipitation patterns. The strong warming trend of the past four decades likely reflects a shift from comparable aerosol and greenhouse gas effects to a predominance of greenhouse gases, as aerosols were curbed by pollution controls, according to former GISS director Jim Hansen.

  • Uncoiling of chromosome occurs
  • Chromatin is formed
  • Spindle breaks down
  • Nuclear membrane or nuclear envelope if reformed

Thus it is clear that the events that are mentioned in the question denote truly about the Telophase.
