Which of the following is an effect of an increase in sea surface temperature?

a. decreased evaporation
b. increased precipitation
c. increased percolation
d. decreased transpiration

The correct answer is increased precipitation.

The conversion of water molecules into water vapor by the effect of heat is called evaporation. The increase in surface area of sea water will increase the evaporation. Increase in evaporation will increase the precipitation because more water will be deposited in the clouds as a effect of increased evaporation which will aid to increased precipitation.

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.
