What else can I help you with?
Depolarization would occur.....a-sodium cations leave the cell b-potassium cations leave the cell c--chloride anions enter the cell d-calcium cations enter the cell?
In a polarized cell membrane there are an excess of sodium cations outside the cell and a relative abundance of potassium cations inside the cell. When a cell depolarizes, sodium ions rush into the cell causing the interior surface of the cell membrane to become slightly more positive, i.e. depolarized. When this happens it triggers potassium channels to open allowing potassium ions to flow out repolarizing the cell. While not completely correct, the best answer of your choices here would be b - potassium cations leave the cell.
What brings water in and out of a cell?
Water enters a cell through the process of osmosis, where it moves from an area of higher water concentration to lower concentration. Water can leave a cell through the process of exocytosis, where vesicles containing water are expelled from the cell.
What will happen if a bacterial cell is placed in distilled water with lysozyme?
The bacterial cell will undergo osmotic lysis due to the hypotonic environment created by the distilled water, causing water to enter the cell and potentially burst it. The presence of lysozyme will further damage the bacterial cell by breaking down its cell wall, making it more susceptible to lysis.
Why do cell enter into meiosis?
Cells enter mitosis to reproduce and grow more cells.
As the concentration of molecules outside a cell increases more molecules will enter the cell?
Yes, this process is known as osmosis. Water moves from an area of low solute concentration (outside the cell) to an area of high solute concentration (inside the cell) to balance the concentration levels. This causes more molecules to enter the cell as the concentration difference increases.
Does it take more power to turn off a cell phone then to leave it on?
It takes more power to leave it on
Immerse a living human cell in a hypotonic solution and water will tend to?
the water molecules will go into the cell since it will move from a concentration of higher to a concentration of lesser. If the cell had more water inside than the surrounding area then the water would leave the cell until an equilibrium is reached between the inside of the cell and the outside of the cell.
Higher salt concentration outside cell than inside what would happen?
Through the process of osmosis, the water inside the cell would leave the cell in order to equalize the concentration of water relative to salt in and outside the cell. The cell would shrink. Salt is not passing through at all.
When the salt solution was added to the onion cells which was the greater concentration (most pure) of water(inside or outside the cell membrane?
The water inside the cell was less salty and therefore had more water than the outside. Water then leave the cells and they will become 'wrinkled' looking or wilted.
What happens if a plant cell contains more solutes than its surrounding environment?
A cell with a greater solute concentration in the external environment is hypertonic state. This means that water will be drawn out of the cell and into the external environment causing the cell to shrivel up.
What is the opposite of a turgid cell?
The opposite of a turgid plant cell is called a flaccid plant cell. A walled cell is flaccid in surroundings where there is no tendency for water to enter. A turgid wall is very form, while a flaccid cell wall is more limp.
After ACh attaches to its receptors at the neuromuscular junction the next step is?
If enough ACh is released, the sarcolemma at that point becomes temorarily more permeable to sodium ions, which rush into the muscle cell and to potassium ions which diffuse out of the cell. Although more sodium ions enter than posassium ions leave.
