Assessment for surfactant level via lecithin/sphingomyelin (L/S) ratio in the amniotic fluid is a direct estimation of fetal maturity. The purpose of surfactant is to prevent the collapsing of the alveoli during expiration.
<h3>Lecithin Sphingomyelin Ratio</h3>
- Clinicians can evaluate fetal lung development using a number of techniques, including the Lecithin-to-Sphingomyelin Ratio (L/S ratio).
- Amniocentesis was used to obtain a sample of amniotic fluid for this biochemical test, which was first developed in the 1970s and used to assess the likelihood that the newborn will experience respiratory distress syndrome (RDS).
- The maturation of the pulmonary system advances with growing gestational age as fetal lung development happens gradually.
- Alveoli don't collapse during expiration thanks to the surfactant's impact. Phospholipids, proteins, and lipids are all components of the surfactant.
- The phospholipids' chemical makeup is significant. One phospholipid in mature surfactant is phosphatidylcholine, also known as lecithin.

Answer:
The third is correct
Explanation:
Usually, a small population like rabbits can be hunted down and eaten by predators like a fox or foxes, and eventually, the fox or all of the foxes will kill the population of rabbits to extinction.
Answer:
<em>The correct option is A) recasting</em>
Explanation:
Recasting can be described as a method for teaching a language in which the instructor corrects the learner by repeating the error back in a corrected format. In this way, the learner recognizes where he made a mistake and tends to understand it.
Parents often use the technique of recasting to teach their children new complex words or to correct them if they speak any wrong word.
