Answer:
dominant and recessive gene... i think
QUICK ANSWERNatural selection leads to evolution because the traits of those who are able to reproduce influence future generations genetics and gradually lead to these passed on traits becoming the normal state of being, thus causing the species in question to evolve. If a group of people have predominantly brown hair genes and have children, then by way of natural selection the dominant gene will increase with future generations, meaning that slowly in time this group of people will evolve to have mostly brown hair genes
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.

I believe it’s the Carboxyl group but confirm online. Hope this helped :))
