Describe the four steps of mitosis: • prophase: • metaphase: • anaphase: • telophase:

PROPHASE ;

1 . chromatin condenses to chromosomes .

2 . centrioles present in the cell duplicates and migrate to opposite poles .

3 . centrioles start making spindle fibres with the aggregation of tubulin protein

4  . nuclear envelope and nucleolus degrades

METAPHASE ;;

chromosomes align along equatorial plate of cell forming metaphase  plate

ANAPHASE''

chromosomes are pulled towards respective poles and sister chromatids no w becomes sister chromososmes , two sets of chromosomes are formed

TELOPHASE;;

nuclear envelope forms around each set of chromosomes and chromosomes un coil to chromatin nuclear division is completed

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.

b. read the phase at the intersection of any given temperature and pressure.
