Preoperational thinker Blake has edged his way close to the top rim of the Grand Canyon. His mother then asks him, "What do you think someone at the bottom of the canyon looking up would see?" Given the egocentric nature of his thought, Blake’s most likely response would be

Option B

Explanation:

Options

a. the sky..

b. the same thing I see..

c. a bunch of little people looking down at me..

 d. I have no idea

Solution -

Because of egocentrism, a child is unable to analyze and view a situation from the perspective of  other person. This is the second stage of Piaget's theory of cognitive development known as preoperational stage which generally starts at the age of 2 and last till the child is of age 7.  

According to Piaget, an egocentric child (beng unable to think of someone’s else perspective) believes that the other person will also see/feel/hear the same as he/she does him/herself.  

Hence, option B is correct

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.
