The reason why I think these fossils are more common fossils than those of soft tissues or microorganisms one reason is that soft tissues decompose better than bone which gives more time for them to be buried.
Answer:
lava flows are very hot, thin and runny. When it cools is has a smooth to ropey texture because of the low silica content which makes it cool quickly. Pahoehoe flows creep along generally at less than 3 feet per minute but some flows have been measured at over 20 miles per hour.
Explanation:
it is A
Tertiary :)
grass = producer
mouse = primary
snake = secondary
As the ion channel opens and allows its movement in an energetical direction. Then it redistributes these ions in opposite direction back across the membrane.
The Na channel opens as the membrane is hyperpolarized. The averaged collective response of single channels resembles the time course of the macroscopic current. Macroscopic currents are blocked by Tetrodotoxin (TTX) but not microscopic currents.
Opening and closing of Na channels are concentration dependent. The function of ion channels inorganic ions (like Na, K, Ca or Cl) to rapidly diffuse their electrochemical gradients that is across the lipid bilayer.
