Answer:
25% heterozygous tall
Explanation:
If we take the F1 generation as parents and let them self-fertilise, we have 4 crosses.
The first one for homozygous tall, then we have 100% AA.
The second and third one for heterozygous tall and we have 25% AA, 50%Aa and 25%aa for each of them.
The last one would be for dwarf, and we'll have 100%aa.
Adding all of them, we'll have
AA = 100 + 25 + 25 = 150%
Aa = 50+50 = 100%
aa = 100 + 25 + 25 = 150%
as we had 4 crosses, so dividing the total percentages by 4, we'll have,
AA = 37.5%
Aa = 25%
aa = 37.5%
:. The percentage of heterozygous tall would be 25%.

Answer:
The correct answer is B transcription factors.
Explanation:
Transcription factor are specific regulatory protein also known as sequence specific DNA binding proteins which regulates the process of transcription in eukaryotic cell.
Transcription factors may either turn on or off the expression of a particular gene to ensure that they are expressed in right cell along with perfect amount and manner.
Transcription factor such as helix turn helix ,leucine zipper, zinc finger play an important role in regulating the activity of many proteins such as DNA ploymerase, helicase
