Why is ice so important to the survival of the polar bear in the arctic? will vote brainliest. a. the polar bears can’t outswim the seals, so they sit quietly on an ice platform and attack the seals when they come up for air. b. the polar bears are hibernating for longer periods of time, so they are not able to get the food necessary to survive. c. the sea ice is important because the polar bears use the ice to go on their migration to warmer land areas d. the sea ice provides a place for the polar bears to take a nice nap in the sunshine.

from the original order (top to bottom) the new order will go

1 (founder)

4 (hawk)

2 (mutate)

3 (next generation)

the answer is; comparing the frequency of collisions with and without the device

this makes the anti-collision system an independent variable and the collisions a dependent variable. if there are fewer collisions with an anti-collision system that without, then it can be stated that the system is a success. essentially, collisions under an anti-collision system are compared with the frequency of collisions by cars with the human drivers.

that would be called plucking : )

explanation:

''plucking, also referred to as quarrying, is a glacial phenomenon that is responsible for the erosion and transportation of individual pieces of bedrock, especially large "joint blocks". as a glacier moves down a valley, friction causes the basal ice of the glacier to melt and infiltrate joints (cracks) in the bedrock."
