All life is based on the chemical element cabon. It is essential to life.
Answer:
Option (2).
Explanation:
The cell potential or membrane potential may be defined as the difference in the electric potential between inside and outside of the cell. The membrane potential of the cell changes during the propagation of action potential.
The resting membrane potential is -70mV. The influx of sodium ions causes the depolarization of the cell membrane. The cell potential changes from -70mV to + 30mV. The membrane potential becomes more positive during the depolarization phase.
Thus, the correct answer is option (2).
Sun is the primary source of energy. There exists some loss of energy when the energy transfers through successive trophic levels. ... So the energy would be always decreasing as we go to higher trophic levels, it can never d ecrease. Therefore, we cannot have an inverted pyramid of energy.
Without knowing the answers, I am thinking it would be either a change in habitat, like climate change or the grass and therefore the herbivores are dying so the lion can't eat. I'm not positive, but it seems most likely.b <span />
The complementary strand on the RNA would be, U-G-G-C-U-C-G-A-A.
