Answer:
This serves to insulate the sea ice, maintaining cold temperatures and delaying ice melt in the summer. After the snow does begin to melt, and because shallow melt ponds have an albedo of approximately 0.4 to 0.5, the surface albedo drops to about 0.75. Albedo drops further as melt ponds grow and deepen.
Explanation:
The remains of traces of an organism preserved from the geologic past.
Canaliculi are tiny canals in bone between osteocytes containing osteocyte cell processes. A spongy bone, also known as a cancellous bone, is a bone with latticelike appearance. A compact bone is a bone that is denser and has fewer spaces than cancellous bone. A compact bone has canaliculi but the spongy bone doesn't, because compact bone tissues form the outer layer of the bone while the cancellous bone tissues form the inner layer of the bone and it does not have osteons. Anosteon is a single central canal, with its contents, and the associated lamellae and osteocytes surrounding it.
