The lack of potable water in an area is a/an what type of limiting factor
a. short term
b. intermediate term
c. long term
d. indefinite

a. Short term

Limiting factor is a factor which limits the growth, abundance and distribution of a population of species in an area or ecosystem. A potable water is a water that can be used for drinking purpose. The lack of potable water in an area can be a short term limiting factor because the technology can be used to purify the water obtained from nearby water source like river, lakes and ponds. Appropriate transportation facilities can help in availing water from other regions.

wheres the answers ?

step 1: initiation

initiation is the beginning of transcription. it occurs when the enzyme rna polymerase binds to a region of a gene called the promoter. this signals the dna to unwind so the enzyme can ‘‘read’’ the bases in one of the dna strands. the enzyme is now ready to make a strand of mrna with a complementary sequence of bases.

step 2: elongation

elongation is the addition of nucleotides to the mrna strand. rna polymerase reads the unwound dna strand and builds the mrna molecule, using complementary base pairs. there is a brief time during this process when the newly formed rna is bound to the unwound dna. during this process, an adenine (a) in the dna binds to an uracil (u) in the rna.

step 3: termination

termination is the ending of transcription, and occurs when rna polymerase crosses a stop (termination) sequence in the gene. the mrna strand is complete, and it detaches from dna.
