There are a couple reasons the ice is important to polar bears, but given the choices you have the correct one would be:
A. The polar bears can’t out swim the seals, so they sit quietly on an ice platform and attack the seals when they come up for air.
The only thing I know is that they have different structures but do the same thing, so their function would be the same. I hope this helps. If not, then let me know and I will do the best that I can. Have a great day!!
The correct option is "D", "<span>The density of seawater".
As you are measuring the</span><span> amount of mass in a volume of water and if we look at the definition of density, it is the mass per unit volume.
D = m/v
where m is the mass of an object and v is the volume.
Thus, d is the correct option.</span>
Static Energy.
Hope this helped. :)
