With water it's the high surface tension property, combined with the fiber construction of paper towels. :)
The endocrine system uses chemicals
Answer:
they bind to protein-coupled transmembrane receptors with higher complexity than those found in prokaryotes
Explanation:
G-proteins are proteins found inside the cells that function as molecular switches which are activated by binding to guanosine triphosphate (GTP), while they are inactive by binding to guanosine diphosphate (GDP). The G-proteins bind to G-protein-coupled transmembrane receptors (GPCRs) in the cytoplasmic region. The GPCRs are a very diverse group of proteins that are activated by extracellular molecules ranging from small peptides to large proteins, including pheromones, neurotransmitters, light-sensitive compounds, etc, thereby allowing them to respond to diverse stimuli from the extracellular environment. In consequence, it is reasonable to suppose that the signaling pathways in which G proteins are involved have a higher complexity level than those observed in primitive prokaryotic organisms.
Answer:
C. The planets would float off into space because the gravitational force of the sun would no longer be there.
Explanation:
I believe this is the answer because a sudden cease in the sun's gravitational pull would cause the planets to continue on a straight path in the direction the sun was pulling them before it ceased to exist.
It reflects all other colors of light therefore except blue. All the spectrums of the light get reflected back.
