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.

<h3>What does a nurse on relief duty do?</h3>
- A nurse who has been given the responsibility by the Medical Center to assist and coordinate the clinical tasks of an organized nursing unit, including providing patient care.
- In the majority of hospitals, a unit charge nurse is in charge of allocating patient shifts to nurses based on prior procedures and experience. The process of assigning nurses to patients is frequently a manual one in which the charge nurse must quickly go through a variety of decision-making criteria.
- Charge nurses need to be extremely empathic in order to succeed in their position. They must be understanding of both their coworkers' and patients' worries.

Answer:
60 to 90
Explanation:
For people 18 and older, a resting is between the range of 60 to 100 bpm ( beats per minute)
Answer:
b. Latent
Explanation:
About 1/3 of the worlds population have TB but do not show any signs or symptoms. This is because during Latency the bacilli is efficiently contained in the lungs by the immune cells such as neutrophils and macrophages.
Answer:
The thyroid gland absorbs almost all of the iodine in the body. When radioactive iodine (RAI), also known as I-131, is given to the body as a liquid or capsule, it becomes concentrated in thyroid cells. Radiation can kill the thyroid gland and any other thyroid cells or tissues (including cancer cells) that absorb iodine, without damaging any other organs.
Explanation:
The thyroid gland is an organ that belongs to the endocrine system and its function is to synthesize hormones that are responsible for controlling the body's metabolism, this gland has an important characteristic and that is that the hormones it produces have a unique chemical composition due to They are the only hormones that contain iodine in their structure, this in turn is essential for its functioning because the body does not synthesize it and it must be consumed in the diet. When a small dose of the radiopharmaceutical iodine 131 (Sodium Iodide 131I) is consumed, it is absorbed into the bloodstream and concentrated by the thyroid gland, where it begins to destroy cancer cells in the gland. 131I quickly attaches itself to thyroid cells to destroy them, but continues to emit radioactivity for a long time: it takes 8 days to halve. The beta radiation particles of 131I, which we call radioiodine or radioactive iodine, have a range of 2mm and act for a long time in a constant way. Fortunately, the body's metabolism quickly expels iodine through the urine, so that in one day the amount of iodine has decreased considerably.
