Cells balance concentrations by using various mechanisms such as passive diffusion, active transport, and osmosis. Passive diffusion allows molecules to move across the cell membrane from an area of high concentration to an area of low concentration. Active transport requires energy to move molecules against their concentration gradient. Osmosis involves the movement of water across the cell membrane to equalize solute concentrations inside and outside the cell.
What else can I help you with?
Why is ammonia toxic to cells?
Ammonia is toxic to cells because it disrupts the pH balance and interferes with normal cellular functions. It can lead to damage of proteins, membranes, and organelles in the cells, ultimately causing cell dysfunction and death. In high concentrations, ammonia can also affect the central nervous system and lead to neurological damage.
What is the significance of solute concentration to osmosis?
Solute concentration affects the direction of water movement in osmosis. Water moves from a region of low solute concentration to a region of high solute concentration to equalize concentrations. This process is essential for maintaining osmotic balance in cells and organisms.
What does iodine do to cells?
Iodine can be harmful to cells in high concentrations as it has a toxic effect by damaging proteins and nucleic acids. However, at lower concentrations, iodine is necessary for the production of thyroid hormones that are essential for regulating metabolism and other bodily functions.
Why does breathing pure oxygen kill you?
Breathing pure oxygen at high concentrations can result in oxygen toxicity, which can damage cells and tissues in the body. This can lead to lung damage, seizures, and even death. The body needs a balance of oxygen and other gases in the air to function properly.
What are sensory receptors that can detect changes in hydrogen ion concentrations?
Chemoreceptors are sensory receptors that can detect changes in hydrogen ion concentrations. These receptors are particularly sensitive to changes in pH levels in the body, helping to regulate processes such as breathing and maintaining blood pH balance.
What would happen to your cells in your body if you drink salt water?
you become dehydrated because thwe concentration of salt is in salt water than in your cells, so water flows out of your cells to balance the concentrations.
When the elodea leaf is moved from salt solution n placed back in water what happens to the cells?
When you deal with problems like this, you need to consider diffusion and osmosis. In this case, you would refer to diffusion, which is the movement of water across a membrane from high concentrations to low concentrations (to try to balance the concentrations). First consider what happens to the cells when you place the elodea leaf in the salt solution; the water in the cells tries to balance the high concentration of salt (sodium chloride) in the surrounding solution, so the water leaves the leaf, thus the cells shrink. Now when you put the elodea leaf into regular water again, there is a higher concentration of water in the surrounding environment compared to inside the leaf's cells, so in attempt to balance concentrations, water goes INTO the cells, thus the cells in the elodea leaf swell (expand).
Where in the body does osmosis take place?
Osmosis primarily occurs in cells and tissues throughout the body, where water moves across semipermeable membranes to balance concentrations of solutes. This process is crucial for maintaining the proper water balance inside and outside of cells.
What happens as a result of the concentrations of solutes in this situation What can happen to the protozoa cells?

How does the water in the cells behave when in high or low concentrations of water?
In high solute concentrations water will flow out of the cell. In low solute concentrations water will flow into the cell.
How do you have your balance not show in all cells in your balance column?
Do not put a formula in the cells where you do not want to show a balance.
Body cells surrounding capillaries usually have?
The body cells surrounding the capillary usually have low concentrations of oxygen and nutrients, but high concentrations of carbon dioxide and other waste products.
How does NaCl affect planaria?
NaCl, also known as salt, can affect planaria by disrupting their osmoregulation. Planaria have a delicate balance of salt concentrations in their cells to maintain proper water and ion balance. Excess salt can cause dehydration, while insufficient salt can lead to swelling and bursting of cells in planaria.
