Electrons become excited in the reaction centre of the Photosystem during the first stage of photosynthesis.
Hey, sorry about the person who gave you a virus... pretty sure most people who leave links are doing similar things unfortunately. The answer is Archaebacteria I’m pretty sure. Eubacteria are found everywhere, Fungi are mushrooms, protists exist all over underwater areas. Haven’t researched it in a while but hope this answer helps :)
Out of the choices given, active and passive transport of solutes across a membrane typically differ because active transport always involves the utilization of cellular energy, whereas passive transport does not require cellular energy. The correct answer is B.
Multiply the percentage of time in each phase by the total time of the cell cycle (720 minutes) and this gives you an estimate of the time spent in each phase
Active transport is a process requiring energy in which a substance crosses the cell membrane. In a resting neuron, there are positively charged sodium ions outside of the cell, and negatively charged potassium ions in the cell. When the neuron fires, depolarization occurs=> the positive ions are forced in and negative ions are forced out by means of active transport. When the neuron is done firing, the ions are forced back into their original position inside or outside of the cell by active transport.
Let me know if I need to clarify any of that.
