What else can I help you with?
What purpose do the cilia serve and where would you find them?
Cilia are hair-like structures found on the surface of some cells. They help in movement of materials along the cell's surface, such as moving mucus in the respiratory tract or moving eggs in the fallopian tubes.
Unlike moving surface water groundwater does not cause erosion?
Groundwater typically moves slowly through porous materials like rock and soil, dissolving small amounts of minerals as it flows. While it can cause chemical weathering and the formation of caves or sinkholes over long periods of time, it does not erode materials in the same way that fast-moving surface water does.
What Sweeps materials across the cell surface?
Cilia and flagella are the structures that sweep materials across the cell surface. These hair-like projections are made up of microtubules and are capable of rhythmic beating, which helps in moving fluids, mucus, or other substances along the cell surface. In certain cells, such as those lining the respiratory tract, cilia play a crucial role in clearing debris and pathogens.
How does a paramcium move?
by moving its cilia, with which its surface is covered
Water moving along the ground's surface?
Water moving along the grounds surface is called a river or a flood.. A river or a flood both contain moving water. River water is consistently moving. A flood will have water moving until it goes away.
What involves moving rocks and soil from the earths surface to expose materials to be mined?
This is called removing overburden, and usually requires heavy machinery; eg: to access coal seams, sometimes entire mountain tops are removed.
How does lubricating machinery-such as the chain on your bike reduce friction?
The surface tension between the metal on your chain pieces is high. The surface tension is low on lubricants like oil or graphite so putting them between moving surfaces provides a opposing surface for both materials that has a low friction.
What is the effect of breeze or moving air on evaporation?
Breeze or moving air can increase the rate of evaporation by removing the water vapor that has already evaporated from the surface, creating a drier environment. This reduces the humidity close to the surface, which in turn allows for more water molecules to escape from the liquid and enter the air.
What purpose do the cilia serve and where would you find them?
Cilia are hair-like structures found on the surface of some cells. They help in movement of materials along the cell's surface, such as moving mucus in the respiratory tract or moving eggs in the fallopian tubes.
Why are small cells better then large cells for moving materials through membranes?
small cells have a greater surface-to-volume ratio than larger cells.
Homophones for writing materials and not moving?
The homophones for "writing materials" and "not moving" are: Stationery (writing materials) Stationary (not moving) Note: These two words have different spellings and meanings, but they sound the same when pronounced aloud.
Which of the folliwing is an example of moving surface water?
A river flowing downstream is an example of moving surface water.
Unlike moving surface water groundwater does not cause erosion?
Groundwater typically moves slowly through porous materials like rock and soil, dissolving small amounts of minerals as it flows. While it can cause chemical weathering and the formation of caves or sinkholes over long periods of time, it does not erode materials in the same way that fast-moving surface water does.
How does moving water effect the earth materials?
Moving water effects the earth materials by slowly eroding or breaking it down.
What type of materials will reflect radio waves?
Radio waves will be reflected by any surface where the electromagnetic properties of the space change. e.g. moving from free space into solid material.
What are the ways that can decrease friction?
1) using a lubricant film between moving parts. 2) using low friction materials, such as Teflon.3) reducing surface roughness.
What is degree of freedom of a particle when moving on a surface?
A particle moving on a surface has two degrees of freedom: one for movement along the surface (translation) and one for rotation around an axis perpendicular to the surface.
