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.
Can a person live on two aveoli?
No, we need many, many alveoli to give the surface area needed for gas exchange.
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.
Do stilts have a large surface area?
No
Why do leaves have a large surface area?

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.
How do you calculate total surface area for aveoli in lungs?
The total surface area of alveoli in the lungs can be estimated using the formula for the surface area of a sphere, as alveoli are roughly spherical in shape. The average diameter of an alveolus is about 0.2 mm, leading to an approximate radius of 0.1 mm (0.0001 m). Given that there are around 300 million alveoli in the lungs, the total surface area can be calculated using the formula ( A = 4\pi r^2 ) for one alveolus, and then multiplying by the total number of alveoli. This results in a total surface area of approximately 70 square meters, providing a large area for gas exchange.
Name one organ in your body which has a large surface area?
The skin is an organ in the body that has a large surface area as it covers the entire external surface of the body.
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.
Why do radiators have a large surface area?
Radiators have a large surface area to increase heat transfer efficiency. The greater surface area allows for more contact between the hot water or steam inside the radiator and the surrounding air, resulting in more effective heat dissipation into the room.
Why is it important that the gills of a crayfish give them a large surface area?
It is important that the gills of a crayfish give them a large surface area because it helps the crayfish to breathe. The bigger the surface area, the more oxygen in the crayfishes system.Ê
