What is the consistency of the madreporite?
The madreporite is a sieve-like plate typically made of calcareous material, such as calcium carbonate, and is located on the aboral surface of echinoderms like sea stars. It is rigid and has a hard consistency to protect the water vascular system from foreign particles.
Is madreporite a part of water vascular system?
Yes, madreporite is a part of the water vascular system in echinoderms. It acts as a sieve to filter water into the system, allowing for hydraulic pressure regulation and movement of tube feet.
When the concentration of free water molecules is higher outside a cell than inside the cell water will diffuse?
into the cell to create equilibrium. This process is known as osmosis. The direction of water movement is determined by the concentration gradient of water molecules between the inside and outside of the cell.
When there is more water outside of the cell than inside a cell water will?
When there is more water outside the cell than inside, water will move into the cell through osmosis. This process occurs as water molecules move from an area of lower solute concentration (outside) to an area of higher solute concentration (inside) in order to balance the solute levels. As a result, the cell can swell and potentially become turgid, or even burst if the influx of water is excessive.
Why was it necessary to match the water levels inside and outside the cooled flask before removing it from the water bath?
So to equalize the pressure inside the flask with that of the atmosphere.
Where does water enter a starfish?
Water enters the starfish through the madreporite or the tube feet, but mainly the madreporite.

What evaporates faster water inside or water outside?
Water outside evaporate faster.
Which structure allows water into and out of the water vascular system?
The structure that allows water into and out of the water vascular system is called the madreporite.
Function of madreporite?
It is a small spot located just off-center on top of a starfish. That is where the water that is used to operate the tube feet is filtered before entering the animal. It is also called the sieve plate.
In words trace the path water takes through the water vascular system?
The water comes into the system via madreporite.
What evaporates faster in fall water inside or outside?
Inside!!
Does water evaporate faster inside or outside or in the frigerator?
Water is evaporated faster outside a refrigerator.
Why does the can crush when placed in cold water?
When a can is placed in cold water, the air inside the can cools down and contracts, creating a lower pressure inside the can compared to the outside. The higher pressure outside the can then crushes the can as it tries to equalize the pressure inside and outside.
What surface are the parts of a starfish visible?
The parts of a starfish that are visible are its upper side, known as the aboral surface, which contains the madreporite (water-filtering organ) and the spines, tube feet, and pedicellariae (small pincers).
How did the Romans get the water inside the Roman Colosseum?
they got the water inside by using pipes from the outside and connect them underground to the inside and let the water flow when they wanted it to.
