A) what are telomeres? b. are telomeres present in both prokaryotes and eukaryotes? c. explain why some cells have telomeres and others don't (base your explanation on the structure of the dna molecule and the directionality of polymerases).

A)     Telomeres are the caps at the end aspect of DNA that defend our chromosomes, which guards the end of a chromosome from corrosion.

B)       Telomeres only exist in eukaryotes, because it possesses the chromosomes from being tarnished by specific molecules in the cell.

C)      The Telomeres are known as to hold a capping function. Its principal mission in the eukaryotes is to defend the end of the chromosome from the DNA deprivation, its repair contrivance and the fusion with other ends. It is also inattentive in the prokaryotic cells because it has a circular chromosomes, therefore Telomeres are needed in their state.

answer;

c. a tree whose roots are surrounded by wet sand.

explanation;

water stress is an important factor limiting the growth and productivity of forests.water stress is the most often cited cause of poor survival and growth of woody landscape plants.

-insufficient soil moisture is the most common form of water stress, but excess moisture that leads to poor soil aeration (hypoxia) can also result in reduced plant vitality. a tree whose roots are surrounded by wet sand would be least likely to experience water stress.
