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.
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.
How erythrocyte are structurally designed to carry oxygen?
Erythrocytes (red blood cells) have 3 main adaptions to carry lots of oxygen: >1) they are a biconcave disk shape. This means that they have a large surface area for the gas to diffuse across. >2) they have lots of heamaglobin- this is the red pigment which combines with oxygen to form oxyheamaglobin, allowing the oxygen to be carried by the cell. >3) they have no nucleus. This means that they have more room to carry the oxygen.
Why is there an advantage to small surface area to large volume ratio?
cause there is
Why do epithelial cells have a large surface area?
Because they're flat.
Why does a red blood cell have a large surface area?
To hold more oxygen.
What component of the blood the oxygen is transported in and how does its sturcture aid its function?
Haemoglobin it has a large surface area
Why do radiators have a large surface area?
They have a large surface area so there is enough area for heat radiation.
Why do gills have a large surface area and are rich in blood?
because in many organisms like fish etc it is an organ for respiration the gills are supplied with capillaries so that the oxygen absorbed can diffuse into the blood it has large surface area so that more oxygen can be diffused in and more co2 can be removed
Why do lungs have a surface area of about 60 metres squared and a good supply of blood?
The large surface area and blood supply allow the largest opportunity for diffusion. Both of these factors make it easier for oxygen to move into the bloodstream and CO2 to move out.
What features of the alveoli mean that gas exchange is more efficient?
They Have A large surface area and they are full of red blood cells
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.
What makes villi good at absorbing food?
large surface area, thin epithelium, highly profused with blood vessels and lymphatics
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. :)
