Oxygen acquisition is easier in air than in water because:
a. oxygen content of air is higher than that of water.
b. oxygen diffuses more slowly in water than in air.
c. more energy is required to move water than air because water is denser.
d. solubility of oxygen in water is relatively low.
e. all of the above.

b

Explanation:

the rate of diffusion of oxygen generate or spread slowly in water until it is evenly distributed

the apgar score is 6

here are the 5 factors that are observed when calculating the apgar index:

skin color

blue everywhere - 0 points

white on the ends and pink on the body - 1 point

all pink - 2 points

heartbeat

absent - 0 points

slow - 1 point

fast - 2 points

reflexes

no answer: 0 points

responds to stimulations: 1 point

cries and coughs: 2 points

muscle tone

soft: 0 point

some bending or stretching: 1 point

active movements: 2 points

breathing

absent: 0 points

weak or irregular: 1 point

good and your baby is crying: 2 points

it is estimated that children whose score is between 8 and 10 are in perfect health and need only routine care. a score between 5 and 7 is representative of a fair condition. often this means that the child has suffered during delivery and probably needs with breathing. as a first step, your doctor will carefully rub the skin of your baby or give him oxygen with a mask.
