Answer:
The correct answer is encephalocele.
Explanation:
The cystic hygroma is a malformation in the neck or upper abdominal area and holoprosencephaly is a malformation or alteration in the facial area, not in the cranial area.
The only one where the shape of the skull is altered (mainly the area of the calotte) is the encephalocele.
Organisms adapt to their changing environment. When there is some pressure in the environment (for example, increased competition for food), then species with the most advantageous adaptations will survive. Because environments change pretty frequently, the organisms living there must cope with this change. This leads to ever changing and evolving species and increased biodiversity. Lastly, a high level of biodiversity leads to a healthy ecosystem because of the vast variety of organisms in that space. Many species allows niches to overlap and therefore no one organism occupies one niche.

The following are the four goals of medicine outlined by the Hasting's Center: (Hanson and Callahan, 1999)
"1. prevention of disease and injury and promotion and maintenance of health;
2. relief of pain and suffering caused by ill health;
3. care and cure of those suffering from a malady and care of those who cannot be cured;
4. avoidance of premature death and pursuit of a peaceful death."

the very basic properties of water
conducts heat
neutral pH
high surface tension
high specific heat
good solvent
how does this help a polar bear, some of it is a stretch but possible benefits
pH - good drinking water, good for marine ecosystem for food
high specific heat - can absorb lots of heat before the temperature rises, polar bears exist naturally in cold environments. (ice) - maybe can tie this in with the natural hibernation cycle
high surface tension - I'm assuming the polar bear walks on the ice at times to get fish
as a good solvent - its probably good that most things dissolve in water, otherwise we would have a lot of floating gunk on top of the water
outside of this, can't give you much more. it has been noted in Shishmaref Village that the ice caps melting is leading to a lack of water in higher mountain areas and polar bears are coming down from the mountain ice cap areas to find food and water
