Answer:
Option D
Explanation:
When amniotic sac breaks and its internal fluid spilled then there are high chances that the fluid may enter into the throat of the infant and may block his/her air passage way. Therefore, in such situation a standard solution is formulated which requires the doctors to suction the air passageway of infant and restrict it from getting choked and contaminated with meconium. A valve mask is primarily used before suctioning
Hence, option D is correct

explanaition i took the quiz and got this one right
if we cross XNXN(normal, non-carrier female) with XnY(color-blind male)
we get XNXn XNY XNXn and XNY

phenotype ratio:2 carrier females and 2 healthy males
The correct answer is C.
The egg sinks in freshwater because it is more dense than the water. So, to make the egg float, you would have to increase the density of the water. Since salt water has a greater density than freshwater, you would add salt to the freshwater, thus causing the egg to float rather than sink.
