Why is surface area of alveoli in lungs is greater than the surface area of the skin?
The surface area of the alveoli is where oxygen and carbon dioxide are exchanged across membranes. A large surface area enables a greater amount of gas transfer. The skin has two main functions: one is holding all our bits in one place and the other is to maintain body temerature. In the latter role, a large surface area is good for cooling the body but bad for keeping warm. So it is a compromise.
Why do leaves have a large surface area?
Leaves are broad, thin and flat to provide a large surface area, to absorb sunlight for photosynthesis. :)
What is the amount of space that the surface of a shape takes up?
Surface Area
Describe what is meant by each of the following terms cell volume cell surface area ratio of surface area to volume?
A cell's volume is the amount of material that can fit into the cell. A cell's surface area is the total amount of material that makes up the outside of the cell. The ratio of surface area to volume is the amount of surface area per unit volume of an object or collection of objects.
The amount of surface is a closed figure?
Area
Organelle has a large amount of surface area?
The Alveoli
What feature of the inner membrane of the mitochondria allows this organelle to produce a great amount of energy?
a large surface area
What feature of the inner membrane of the mitochondria allows this organelle to produced a great amount of energy?
a large surface area
What do alveoli have that enables them to absorb a large amount of oxygen?
A large surface area
What is the purpose of folds and wrinkles of membranes?
to provide a greater surface area in the organelle (increase surface area)
Why do radiators have a large surface area?
They have a large surface area so there is enough area for heat radiation.
An adaptation to increase the surface area of a part of a cell that is involved in cellular respiration?
Rugae is the folding of the surface of an organelle to increase the surface area of a volume.
Why does a small amount of water melt faster than a large amount of water?
A small amount of ice generally melts faster than a large amount of ice because of the difference in surface-area to volume ratios. Heat transfer with the surroundings occurs only at the boundaries of the ice. The rate of melting is thus directly proportional to the surface area. Additionally, the amount of ice to be melted is dependent on the volume. The more ice, the longer it takes to melt. Thus, a small cube of ice will melt faster because it has a greater surface area to volume ratio than a large block of ice.
What provides a large surface area for gas exchange?
Your lungs provide a very large surface area for gas exchange.
What term means amount of space on a surface?
surface area
It is possible to increase the amount of pressure by the amount of area where force is applied.?
The surface area
Which will dissolve faster a substance with little surface area or the one with a large surface area?
One with a large surface area because the solvent will be able to dissolve more solute simultaneously.
