Answer:
an apple causes antibiotic resistance
It is incorrect its B.tropism
Answer:
The correct answer is - False.
Explanation:
Water vapor is water in its gaseous state. Water vapor is totally invisible, an individual can not see water vapor in any situation with naked eyes. Fog, clouds, mist are not the water vapor as they contain liquid water or droplets.
Water vapor is essential for the weather and climate, without water vapor there would be no rain, snow or clouds as require water vapor to form.
Thus, the correct answer is - false.
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.
