Which of the following adaptations enables deciduous trees to produce more food?
a.
thick bark
b.
stretching toward the sun
c.
leaf loss
d.
color change

Thick bark is the adaptation that enables deciduous trees to produce more food.  

Deciduous trees are trees such as oak, maple, and hickory trees which lose their leaves for part of the year. Bark is an important part of a tree that protects the tree. The thick bark of the deciduous trees is composed of many layers and it provides the tree with the necessary nutrients and moisture it needs for its growth.

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.
