Broken up by the teeth and mixed with saliva, which lubricates it so its easier to swallow.
for increasing the surface area on which enzyme action can take place.
no
it's the problem of surface area -to- volume ratio that mean there is no fitting between increasing of surface area and increasing of volume
area
increasing of temperature >> increasing concentration
Kinda of a combination of both. The surface of a 3-D object is called surface area.
no
Villi are tiny fingerlike projects that increase a cells absorption capabilities by increasing its surface area.
The surface area of the cerebral cortex is increased by its folding into gyri and sulci. This folding allows for more neurons to be packed into a smaller space, increasing the brain's processing power without significantly increasing its size.
Look in the book broseff.
Factors that can increase the rate of diffusion include increasing the concentration gradient, increasing temperature, decreasing the distance for diffusion, increasing surface area, and reducing the size of the molecules diffusing. Factors that can decrease the rate of diffusion include decreasing the concentration gradient, decreasing temperature, increasing the distance for diffusion, decreasing surface area, and increasing the size of the molecules diffusing.
In the mouth, where digestion begins, food is reduced to smaller pieces by the teeth, increasing its surface area. The saliva begins the chemical break-down of the food and lubricates it for easier swallowing.
