A
Explanation:
There are different mechanisms for transport of molecules across the cell membrane. One kind of this transport is facilitated diffusion, this is a form of passive transport, not requiring any ATP (the opposite would be active transport, where it does require ATP.
Simple diffusion does require special transport proteins, and neither does osmosis. Filtration is a technique used for sterilisation of water, where any impurities can be drawn out of the liquid
The electrons that chlorophyll loses in the electron transport chain are replenished by water molecules. These water molecules degrade releasing oxygen and hydrogen, the electrons are then supplied to the electron deficient chlorophyll molecules located in the reaction centre of the Photosystem.
<span>The
answer is The frontal lobe is in charge of the more accurate, reasoned choices associated
with adulthood. Adolescents are more likely to process emotions in the
amygdala then adults who use the frontal lobe. One of the reasons for bad
decision making in adolescents is the immaturity of the prefrontal cortex.
