Identify the accurate statement regarding prenatal development and birth. the development of the central nervous system is completed during the embryonic period. in the last months of prenatal life, the lungs begin to expand and contract and the valves of the heart undergo final maturation. a baby cannot be both preterm and small-for-date. a 36-week fetus will not yet have developed sufficient lung function to survive on its own.

Option  B

Explanation:

The prenatal development of the fetus is very important in order for the fetus to live a healthy life outside the womb.

The vital organs of the fetus must be fully development before delivery of the fetus. The kidney, lungs and brain must be fully developed else the fetus can get exposed to many disease since birth.

The last months of the prenatal development includes the expansion and contraction of valves of heart which undergoes the final maturation.

answer:

the water molecules are transferred from the roots to the stem or top parts of the tall tree because of important properties of water which are adhesion, cohesion and capillary action. cohesion is the property of water molecules keeps water molecules in a combined state by sharing of bonds between them at the atomic level. adhesion allows the interaction of water molecules with other substances or substrate. adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. capillary action occurs when the adhesive force to the vessel wall is stronger than the cohesive force between water molecules. capillary action mimics the transfer of water from a tube or pipe. in this way water utilizes its property to transfer water from down to top level of the plant.  

not only is it colder, it also becomes darker, less salty, and more dense.
