Answer:
Anaphase
Explanation:
Before the mitosis process (where cells multiply creating two new daughter cells from a single cell) chromosomes are replicated and remain attached to their replicates, then they are condensed forming microtubules as they align on the metaphase plate. <em>Now the sister chromatids (replicates) begin to separate to the opposite poles due to the action of the spindle in </em><u><em>anaphase</em></u> (You can observe this in the image I added). Then telophase begins when the nuclear envelope forms back again and chromosomes begin to unroll.

Answer:
1) In trophic levels, producer are organisms which has the ability to make their own food e.g plants and algae. Primary consumers are the organisms which feed on producers e. g deer and zebra etc. Secondary consumers are those which feed on primary consumers and tertiary consumers are those organisms which take energy by feeding on secondary consumers e. g tiger and lions. The pyramid get narrower at each higher level because when we moves upward, the population of organisms decreases.
2) Environmental sphere refers to all the materials that are present in the environment. There are five sphere which are given below.
1) Lithosphere: This sphere comprise of land on which all living organisms lives.
2) hydrosphere: It refers to water bodies.
3) biosphere: It is the living part of the environment.
4) atmosphere: This sphere contains gaese which are necessary for survival.
5) cryosphere: This sphere contains water in stored form.
3) A cycle in which chemical moves from living and non living things to the atmosphere.
1)carbon goes to the atmosphere through respiration and burning of fuel.
2) phosphorus is released after the burning of plant body.
3) nitrogen is released in denitrification process and industries.
4) oxygen is released in the atmosphere through photosynthesis.
5) sulfur is released in the atmosphere through volcanic eruptions.
