Albedo scale: 0 = absorbs, 100 = reflects (snow ≈ 95%).
1. What does an albedo of 0 indicate for incoming solar radiation?
2. Which combination of traits best matches polar bear adaptations for life on ice?
3. What is meant by a distributed nervous system in octopuses?
Albedo — meaning?
Fraction of solar radiation reflected by a surface
Snow reflectance — percentage?
Up to about 95%
Polar bear adaptations — traits?
Insulating fur, black skin, high fat, streamlined body, white camouflage, wide hind legs, fat-based hydration
Octopus distributed intelligence — system?
Decentralized processing across arms and central brain
Arms acting independently — reason?
Semi-autonomous actions enabled by distributed neural control
Octopus learning — capability?
Arms can learn locally; knowledge transfer occurs between arms
