Has a penguin got a small area of volume ratio?
Yes, the larger the surface area to volume ration the more the heat loss is, therefore, they've got smaller surface area to volume ration.
How does an elephant use it's huge ears to keep cool?
Elephant ears have a very large surface area to volume ratio - with blood vessels spread out throughout. This means that the blood vessels are close to the surface, allowing for heat to radiate out. Elephants can also use their ears to fan themselves with - they are large so create a nice breeze.
How does an earthworm increase its surface area to volume ratio?
with the mucus
Why do cats curl up into a ball when cold?
It has to do with volume vs surface area. All things lose heat through the surface. The bigger the surface, the more heat lost. An animal curled into a ball presents the least amount of surface area for its volume, which means it takes the least amount of energy to keep warm.
What is a problem faced by animals as they increase in size?
decreasing surface-to-volume ratio
How does a cell's ratio of surface area to volume change as the cell grows larger?
As the cell grows larger the ratio of surface area to volume increases. Larger cell = more volume for the amount surface area.
What is the mass and volume of a housefly?
The mass and volume of a housefly can range quite a bit. The mass of a housefly can be around 12 milligrams and the volume is usually between 5-7 millimeters.
Is true that small cells have larger surface area to volume rations than do larger cells?
Cell have a greater surface area to volume rations than a larger cell.
Which statements about the ratio of cell surface area to cell volume is are correct?
Larger cells will have a greater surface area-to-volume.
How does cell's ratio of surface area to volume change as the cell grows larger?
because it has the surface area of volume
What happens to surface area to volume ratios for larger and larger cubes?
They grow
As a cell becomes larger what happens to its surface area and volume?
The Volume increases faster than the Surface Area
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.
What happens to the surface area to volume ratio when folds are made in a cell's outer membrane?
The surface area to volume ratio will increase
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.
As a cell gets larger its surface area to volume ratio?
... will decrease.
Describe what happens to the surface area to volume ratio for larger and larger cubes?
For a cube with edge length, L. Surface area = 6L2. Volume = L3. So ratio of Surface Area / Volume = 6 / L. Therefore, as the side length, L, increases, the ratio will decrease.
