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: - few nutrients

high pressure

low temperatures

explanation: 1. few nutrients:   open-ocean zone is located way far from the land, which is the main source of the essential nutrients.2. high pressure: pressure increases by 1 atmosphere for every 10 meters increase in depth.3. ample sunlight: a large fraction of the sunlight is reflected back to the atmosphere from the sea surface. 4. varying salinity: below the thermocline, the water is isolated from the atmosphere so the salinity remains stable over the year.5. low temperatures:   the temperature of open-ocean zone ranges from a low of -2°c to an average of 17°c
