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
Synaptotagmin — role?
Membrane protein controlling neurotransmitter release timing
Synaptotagmin mechanism — steps?
Ca2+ binds C2 regions, triggers SNARE, vesicle fuses, releases neurotransmitter
Synaptotagmin-1 — significance?
Supports fast neurotransmitter release for rapid behaviors
RNA editing — process?
Post-transcriptional modification changing RNA sequences
ADAR1 — enzyme?
Adenosine-to-inosine RNA editing enzyme
A→I editing — effect?
Inosine read as guanine, shifting protein coding potential.
