1) 75% purple flowered and 25% white flowered. If you complete the punnett square, you'll see the combinations are PP, Pp, Pp, and pp. The capital P is dominant (purple), so you know that 3/4 combinations will be purple flowers.
2) 50%. There is a 50% chance Grace will have Huntington's disease because since the disease is dominant, it is capital letter H. When you make a punnett square, you'll see the combinations are Hh, Hh, hh, and hh. There is a 50% chance Grace will have the Hh combination.
3) Protein. Protein is the only bio-molecule out of the 4 options, and the diagram shows a protein being made.
4) Transcription. Transcription is when the genetic message from DNA is transcripted onto mRNA.

c) To send signals to the blood vessels to constrict or dilate, to decrease or increase blood flow, respectively.
Explanation:
The nervous tissues comprises of nerve cells, which functions by sending and receiving electric signals as information in order to bring about specific responses.
The system majorly in charge of transport in the body is the circulatory system. Hence, the nerve cells send signals to the blood vessels to constrict or dilate, to decrease or increase blood flow, respectively.
Any trait which has a completely genetic basis with no environmental factors playing any role are traits that are inherited in a completely environmental fashion. There are some traits which are purely genetic and are therefore also determined only through genes. However, the majority of (phenotypical) traits are inherited and determined both by genes and environment.
