Open the cage, haha. On a serious note if the bird isn't trained you should block the exit with your hand so you can capture it and it doesn't fly away.
Answer:
The cause of respiratory distress syndrome in premature infants is <u>lack of surfactant in the lungs because the lungs has not fully developed.</u>
Explanation:
Respiratory distress syndrome is a type of neonatal disease of respiration caused by the lack of surfactant production by the lungs.
Normally the lungs of fetus start the formation of surfactant during the third trimester of pregnancy (26 weeks through labour and delivery ). The surfactant is produced by type II alveolar cells and is the lipoprotien complex that has surface tension lowering effect (surface active agent ) having both hydrophobic and hydrophilic properties thus coats the air sacs and alveoli.
In the premature infants, the lungs are not fully developed hence the adequate amount of surfactant is missing thus resulting in Respiratory distress syndrome.
<h2>
Option (B) is Right Answer</h2>
Explanation:
(B) chromatids are attached to one another
- <em>The linkage between the sister chromatids </em>is particularly critical at centromeres because it ensures right <em>microtubule connection to the kinetochores </em>
- In eukaryotes, a centromere is a district of DNA that is responsible for the development of the imitated chromosomes into the<em> two daughter cells during mitosis and meiosis</em>
- There is one centromere on every <em>chromosome and centromeres are responsible for two major functions</em>
