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.
The infant would most likely display physical facial abnormalities, smaller than usual head size, thin upper lip, deformities of fingers and joints, etc. When the baby starts to develop more and get older, there will be learning problems such as speaking and issues with impulse control
Skeletal muscles contain connective tissue, blood vessels, and nerves. There are three layers of connective tissue: epimysium, perimysium, and endomysium. Skeletal muscle fibers organized organized into groups called fascicles. ( hopes this helps!)
Answer:
The answer is Letter B
Explanation:
Decreased excretion of the substance and an increased amount of the substance in blood
Respiratory rate increased from 16 to 19 breaths per minute is vital signs during activity would be the best indicator that the client is tolerating mild exercise.
Your body utilizes more oxygen during exercise and creates more carbon dioxide when your muscles perform harder. Your breathing has to increase from about 15 times per minute while you are resting to about 40–60 times per minute while you are exercising in order to meet this additional requirement. To supply the body with oxygen more quickly, breathing rate rises. To more effectively get the oxygen (and glucose) to the breathing muscles, the heart rate increases. These procedures call for oxygen. Because of this, when an activity is completed, a person's respiration and pulse rate do not immediately return to normal. The oxygen debt is the quantity of oxygen needed to flush out the lactic acid and replenish the body's oxygen stores.
