When it comes to movement of particles in an out of cells, there are two basic types of transportation, these are passive and active transportation. The passive transportation of particles does not require the use of energy while the active transport system requires the use of energy in the form of ATP. From the diagram given in the question, it can be seen that energy is involved in the process. Energy is mainly needed to move the particles against the concentration gradient since the inside of the cell is highly concentrated while the outside has low concentration. <span />
Answer:
it has partial charges
The hydrogen gives a positive partial charge
The oxygen gives a negative partial charge
Oxygen is way more electronegative than hydrogen therefore the molecule will be polar.
The brain injury suffered by Phineas allowed psychologists to learn about the functions of the brain's FRONTAL LOBE.
The man case was the first one in which a brain damage will result into a change in personality. The damage to the Phineas frontal lobe helped scientists to recognize the connection between the frontal lobe of the brain and social cognition and decision making.<span />
