What is the driving force of the membrane?
The driving force is explained by two factors: voltage gradient and concentration gradient. When there are more ions inside of a cell than outside of a cell, the concentration gradient is pushing the ion to exit the cell. This is simple diffusion. If that ion carries a negative charge then it also wants to exit the cell because the outside environment is slightly more positive.So if you add both voltage gradient and concentration gradient you get the driving force. In the example above both gradients are pushing the ion outside of the cell. Sometimes you can have the gradients going in opposites and then the driving force will be determined on which gradient is stronger.
Explain how pressure operates within a plant cell to help it keep its shape?
The central vacuole in a plant cell stores water and other materials. As it fills up, it becomes more rigid. This helps the plant cell maintain its shape and support the entire plant.
What prevents cell bursting?
Cells are protected from bursting by their cell membrane, which is a semi-permeable barrier that regulates the flow of substances in and out of the cell. This membrane is able to stretch and expand as the cell takes in water, ensuring that the cell doesn't burst. Additionally, cells have mechanisms to actively regulate their internal osmotic pressure to prevent excessive water uptake and swelling.
What role does the hormone oxytocin play in the process of milk ejection during breastfeeding?
Oxytocin is a hormone that is released during breastfeeding and plays a crucial role in the process of milk ejection. It causes the muscles around the milk ducts in the breast to contract, pushing the milk out into the nipple for the baby to feed.
What is the process called when bones increase in width?
The process of bones increasing in width is called appositional growth. This occurs when new bone tissue is added to the existing bone surface, resulting in an increase in bone diameter.
Function of cytoskleton in cell membrane?
Cell structure integrity and movement, which includes moving vesicules, pushing the cellular membrane to engulf something or to project a pseudopodium.
What is the process of muscles pushing down food into your body?
peristalses
Describes the effect of a situation of scarcity?
There's a shortage of oil, pushing car companies into researching alternative feuls.
The chief force pushing water and solutes out of the blood across the filtration membrane is?
glomerular hydrostatic pressure (glomerular blood pressure)
What chief force pushing water and solutes out of the blood across the filtration membrane is?
The chief force pushing water and solutes out of the blood across the filtration membrane in the kidneys is hydrostatic pressure. This pressure is generated by the blood flow entering the glomerulus and helps drive the filtration of water and small solutes into the kidney tubules to eventually form urine.
What gets created by the physical process that change earth's surface by pushing its crust up or wearing it down?
Mountains are created by the physical process of pushing the Earth's crust up, while valleys and canyons are formed by the process of wearing down the crust through erosion.
What best describes the effect of a situation of scarcity?
There's a shortage of oil, pushing car companies into researching alternative fuels. APEX
The process of pushing registry changes from memory to a hard drive file is known as?
Flush
What is the process of moving?
to move something an object as in moing into a different are by pushing or moving. by-ag
Which of the following accurately describes the effect of a situation of scarcity?
Theres a shortage of oil, pushing car companies into researching alternative fuels
What is the process of pushing denser oceanic crust under the less dense continental crust?
subduction
Is pushing a cart through a store more like active transport or passive transport Why?
Pushing a cart through a store is more like active transport because it requires energy and effort to move the cart against resistance, such as friction or gravity. Active transport involves moving substances across a membrane against a concentration gradient, which also requires energy. In contrast, passive transport occurs naturally without energy input, like a ball rolling downhill. Therefore, the act of pushing a cart involves an active process similar to active transport.
