What else can I help you with?
Why are groups of a small cells better than one large cell at moving material in and out?
they have a greater surface-to-volume ratio
How large can a single cell be and why?
The size of a single cell is limited by the cell's surface area to volume ratio. As a cell grows larger, its volume increases faster than its surface area, which can lead to problems with nutrient exchange and waste removal. Therefore, cells have evolved to be small in order to maintain an efficient surface area to volume ratio.
Why is there an advantage to small surface area to large volume ratio?
A small surface area to volume ratio allows for more efficient exchange of substances (like nutrients and waste) with the environment. It also helps retain heat better in cold environments and reduces water loss in dry environments. Additionally, smaller surface area minimizes exposure to harmful external factors.
Why are metabolically active cells limited to very small sizes?
They are more metabolically acitve then larger cells because they have a smaller surface area to volume ratio then the larger cells which means the enzymes and proteins can move around faster and this makes the cell metabolically active.
How does a ratio of surface area to volume describe a cell?
The ratio of surface area to volume is important for cells because it influences the ability of a cell to exchange materials with its environment efficiently. As cells grow larger, their volume increases more rapidly than their surface area, leading to a decrease in the surface area-to-volume ratio. A high surface area-to-volume ratio allows for a more efficient exchange of nutrients and waste products, enabling the cell to function optimally.
How will surface area to volume ratios of a small cell compare to those of a large cell?
A small cell will have a larger surface-to-volume ratio.
What organ in the digestive system has an extremely large surface to volume ratio?
the small intestine
How does surface area to volume ratio affects an organism?
If the surface area of the organism is small, then there is no problem with getting all the oxygen needed. If the surface area of the organism is large, therefore a special respiratory surface is needed. An example is lungs, gills. The ratio of surface area to volume in a small organism is greater than the ratio in a large organism.
Why does it take less time for small to wear away than it does for large rocks to wear away?
Small rocks have a larger surface-to-volume ratio , and are therefore more quickly weathered compared to a large rock with a lower surface-to-volume ratio.
Why do larger animals keep their body heat better than smaller animals?
This is because of the surface to volume ratio. A small mammal has a larger surface area, as compared to its volume, than a large mammal does, so a small mammal's surface area to volume ratio is bigger. A large surface to volume ratio causes things to pass into the organism and out of the organism more easily, so a mammal with a large surface to volume ratio (a small mammal) will lose heat more easily in a cold environment than a mammal with a small surface to volume ratio (a large mammal).
Why does it take less time for small rocks to wear away than it does for large rocks wear away?
Small rocks have a larger surface-to-volume ratio , and are therefore more quickly weathered compared to a large rock with a lower surface-to-volume ratio.
Why are groups of a small cells better than one large cell at moving material in and out?
they have a greater surface-to-volume ratio
Why are groups at small cells better than one large cell at moving material in and out?
They have a greater surface-to-volume ratio
Why are small cells better then large cells for moving materials through membranes?
small cells have a greater surface-to-volume ratio than larger cells.
Why can small cells exchange subtances more readily than large cells?
Small cells have higher surface area to volume ratio than larger cells.
The effects of body size on heat loss?
A bigger animal has a small surface area in relation to their large volume. Smaller animals have a bis surface area to volume ratio which mean heat is easier to be lost.
Is the surface-area-to-volume ratio of a small cell less than that of a larger cell?
As a cell becomes larger the surface area to volume ratio gets smaller. The volume increases by the square of the surface area. That is the main reason that one celled organisms are small.
