Biologists think that endosymbiosis gave rise to mitochondria before plastids partly because: (All eukaryotes have mitochondria whereas many eukaryotes do not have plastids)
"So maybe I never really gave myself a fair chance. I did pick up the basics pretty easily, and I might have become a good pianist at that young age. But I was so determined not to try, not to be anybody different that I learned to play only the most ear-splitting preludes, the most discordant hymns"
this is a quote you can use from the book “two kinds” by amy tan that could be considered “encouraging”!
hope this helps :)
It would be impossible to feel them move because they are moving to slow for us to realize it. Well, that is what I think.
A river that comes from rain, glaicers etc would be a good example of fresh water rivers. Cause the water is coming from something that is most likely been unthouched by man or has been filterd and cleaned from minerals in the ground.
Depolarization is to excitation, while Hyperpolarization is to inhibition.
Option 4 is correct.
Hyperpolarization is opposite of Depolarization.
Depolarization is a process by which cells undergo a change in membrane potential. It is a process of shift in electric charge that results in less negative charge inside the cell.
Hyperpolarization is when the membrane potential becomes more negative at a particular spot on the neuron’s membrane.
