Answer:
what do u wanna to ask.......
pls re-post the question...
The four principles of natural selection are variation (organisms within a population have their own individual differences in their appearance, such as, markings and color), inheritance (traits passed down to the offspring), high rate of population growth (which leads to their local resources to be more of a challenge to find), and differential survival/ reproduction (organisms in the population with stronger traits are more likely to survive and reproduce, aka survival of the fittest). These four principles work together to respond to chance in the environment by making sure the strongest survive and over time that species will adapt to their environment because the organisms with the better suited traits will pass their traits to its offspring.
I hope that made sense, lol.
Answer:
No.this does not cause action potential.
Explanation:
Action potential is formed from the influx of sodium ions through the special sodiun channels call volatage gated channels.
The influx caused deoplarisation and if upto to the threshold level give action potential.
The influx of sodium and out flux at the node of Ranvier does not lead to action potential neither does hydrolysis of ATPs for its active transports process.
The sodium pump is for maintenance of electrochemical gradients with potassium for maintaining Resting Membrane Potential of the neuron.
The main function of the articular cartilage is to provide a smooth surface where the bones connect and touch. It also lubricates that area and makes sure there is low friction. To cusion the bones from rubbing and smacking on each other.
