The answer to this question would be: <span>(2) cytoplasm
The nucleus is the organelle in middle of the cell that contains DNA. The ribosome is organelle that has a function in protein synthesize. Mitochondrial has a function in making the energy. Cytoplasm is water inside the cells. Everything would be stored inside it and moving material will need to pass it.</span>
Answer:i'm pretty sure its C: into cells
Explanation:
Molecule is formed when atoms combine by covalent bonding. The molecule may be polar or non polar.
Answer:
A) A decrease in Na+ permeability, and an increase in K+ permeability.
Explanation:
When the potential action reaches a peak of about +40 mv Na+ channels are open and a high number of Na+ ions are entering the inside of the cell. Shortly after this happens the K+ channels will start to open their gates increasing the cell K+ permeability while the Na+ channels will start to close their gates, so the Na+ permeability will decrease. This happens in order to valance the positive charge on the inside of the cell. Normally the inside has a negative charge while the outside has a positive one, as the inside is more positive due to the increase in Na+ permeability at the beginning of the potential action, K+ cations (which are in abundance in the cell) will have to go out through the K+ channels so as to restore the charge valance, that means that there is an increase in K+ permeability.
