Answer:
Explanation:
Peripheral membrane proteins are found on the outside and inside surfaces of membranes, attached either to integral proteins or to phospholipids. Unlike integral membrane proteins, peripheral membrane proteins do not stick into the hydrophobic core of the membrane, and they tend to be more loosely attached.
The question is incorrect. The correct question is as follows:
The nurse is orienting a new RN in the care of a patient with respiratory distress due to emphysema. The patient is being treated with O2 via a Venturi mask with 35% oxygen. Which statement by the new RN indicates that teaching has been effective, when the nurse questions the new RN about the use of the Venturi mask?
a. "A nasal cannula will dry the mucous membranes and cause an increased risk of infection."
b. "Her alveoli cannot absorb higher levels of O2 because of the emphysema."
c. "Her alveoli have been damaged and may rupture with higher doses of O2."
d. "Her respiratory center requires low O2 concentration to stimulate breathing."
Answer:
Her respiratory center requires low O2 concentration to stimulate breathing."
Explanation:
COPD ( Chronic obstructive pulmonary disease) may be defined as the combination of the different lung disease that might create problem in the respiration process.
The venturi mask is used in the medical condition to provide the proper amount of oxygen to the patient. In emphysema the individual suffered from the hypoxemia means low oxygen level in the body. The low oxygen is required to the patient and high oxygen level will disturb the normal process of breathing.
Thus, the correct answer is option (d).
1. They both involve duplication of a cell's DNA content.
2. Mitosis is for asexual reproduction and meiosis is for sexual reproduction.
3. Mitosis produces 2 cells and meiosis produces 4.
Answer:
The correct answer is c. 3/16.
Explanation:
In the given question two traits being studied, the traits are flower color and seed shape.
This is a typical Mendel’s dihybrid cross. According to the question purple colour (P) and round seed (R) are dominant traits.
When heterozygous purple-flowered (Pp), round-seeded (Rr) individuals are crossed, four different types of plants are produced phenotypically in the ratio 9:3:3:1.Out of 16 offspring, 9 are purple flowered, round seeded pea plants, 3 pea plants are white-flower with round seed, 3 are purple- flower with wrinkled seed and 1 pea plant is white-flowered with wrinkled seed pea plant is produced.
