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 are the characteristics of respiratory surface?
large area
What organelle has a large amount of surface area?
The Alveoli
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 is a catalyst spread over a large surface area?
So it is more efficient.
What cause distruction to aveoli?
Aveoli can be damaged by obsessive smoking and general air pollution from burning fossil fuels (Such as coal). When aveoli is damaged, it loses surface area and therefore you cannot absorb enough oxygen to keep yourself healthy.
Can a person live on two aveoli?
No, we need many, many alveoli to give the surface area needed for gas exchange.
Why do radiators have a large surface area?
They have a large surface area so there is enough area for heat radiation.
Why must all respiratory system have a large surface area over which air can pass?
You have barile? Lungs have hierarchical structure which minimizes volume but maximises surface area Aveoli are the smallest units of structure and are the site of gaseous exchange: - They are circular = max surface area for min volume - Their most surfaces faciliate the exchange of gases - They have extensive blood supply which also faciliate the exchange
What provides a large surface area for gas exchange?
Your lungs provide a very large surface area for gas exchange.
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.
Do stilts have a large surface area?
No
Why does a small pin sink wheras a large boat does not?
Because a pin has a small surface area and a boat has a large surface area.
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 are the characteristics of respiratory surface?
large area
What stars are cool and bright stars?
To be bright you need to be hot, close or have a large surface area. The brightest coolest stars are red super giants. They have such a large surface area, that even though their surface temperature is cool - in star terms - their large surface area makes them appear bright.
Are roots adapted to take in water because they have a small surface area?
No.Plant roots have large surface area,roots have root hairs to increase the surface area so that large amounts of water can be absorbed easily.
