Answer:
Trans urethral removal of bladder tumour (TURBT)
Explanation: it is a treatment for early bladder cancer. tumors are removed by surgeon from urethra. urethra is a tube that excretes urine from the body. following are the list of instruments used in TURBT procedure:
- cystoscope (it has light and camera at one end that helps surgeon to cut tumours out of the bladder lining)
- electrified loop of wire(it cuts the tumours it is present at the end of the cystoscope it seels off bleeding vessels)

<u>imp point:</u>
there will be no cuts (incisions) on the outside of your body.

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.

Explanation:
Glutamate is the major excitatory neurotransmitter in the brain and plays a critical role in the acute and long-term effects of nicotine
Reduced blood volume leads to collapsing vessels, reduced pressure, and subsequently reduced perfusion pressure. The cardiovascular system combats low blood volume by constricting blood vessels until the body reaches a blood pressure that restores proper perfusion pressure.
