Answer:
The three methods are: 1) Using H-Ras- SREBP- 2 Fusion proteins, the NH2 segment can be released by two sequentia
Explanation:
Sterol regulatory element binding proteins (SREBPs) are transcription factors attached to the endoplasmic reticulum. The NH2-segment, which activates transcription, is connected to membranes by a hairpin anchor formed by two transmembrane sequences and a short lumenal loop. Using H-Ras–SREBP-2 fusion proteins, we show that the NH2-segment is released from membranes by two sequential cleavages. The first, regulated by sterols, occurs in the lumenal loop. The second, not regulated by sterols, occurs within the first transmembrane domain. The liberated NH2-segment enters the nucleus and activates genes controlling cholesterol synthesis and uptake. Certain mutant Chinese hamster ovary cells are auxotrophic for cholesterol because they fail to carry out the second cleavage; the NH2-segment remains membrane-bound and transcription is not activated.

I hope this helps :)
Explanation:
A doctor could do multiple things.
- The dctor could first prescribe the teen something to increase the Vitamin D deficiency.
- The doctor could also try to find out why the teen is not eating and try to fix it.

- The doctor could also have the teen go to a pyshiologst, so the teen can talk out his/her problems on why the teen is not eating and how they can fix it.
