A nurse administers two serial intramuscular injections of betamethasone to a woman at 32 weeks' gestation who has been admitted in preterm labor. the nurse knows that this medication is given to stimulate fetal surfactant production. The presence of this surfactant factor in the pulmonary alveoli is essential for adaptation to extrauterine life. The surfactant is a substance that significantly reduces the surface tension within the pulmonary alveolus, preventing collapse during expiration.
The four phases in the life cycle of a cell and place the events in order, starting with events that occur immediately after the cell was born are:
- The first gap (G1)
- The synthesis (S)
- The second gap (G2)
- M
<h3>What is a cell?</h3>
A cell can be defined as simplest, basic, functional and structural unit of life

Answer:
Astronomers define star brightness in terms of apparent magnitude — how bright the star appears from Earth — and absolute magnitude — how bright the star appears at a standard distance of 32.6 light-years, or 10 parsecs. (A light-year is the distance light travels in one year — about 6 trillion miles, or 10 trillion kilometres.) Astronomers also measure luminosity — the amount of energy (light) that a star emits from its surface.
