When wax is rubbed on cloth the cloth becomes waterproof why?
the force of cohesion bw water molecules is smaller than the force adhesion bw water & cloth molecules so the cloth molecules becomes wet with water,but if a little wax is rubbed over it then the force of adhesion bw water & wax molecules becomes smaller than the cohesive force bw water molecules.So the water cannot make the cloth wet now

What does real difference mean in science?
There are two ways to work out the real difference mean in science. Firstly, the real difference means when the ranges for two different values do not overlap. If they do overlap, then there may not be a difference in the true value. Secondly, if there is a real difference, the range of one value should not overlap the mean of another value.
How does the sponge keep water flowing through its ostia and out through the osculum?
The sponge works like a chimney. Water rushes in from beneath through ostia and comes out ffrom osculum. This action is continuously controlled by wholly or partially closing the osculum and ostia and varying the beat of the flagella, and the pores may shut if there is a lot of sand in the water before it could block the system.
What is ostia and osculum?
Ostia and osculum are terms used in the context of sponges, which are simple aquatic animals. The ostium (plural: ostia) refers to the small openings on the surface of a sponge through which water enters, while the osculum (plural: oscula) is the larger opening at the top through which water exits. This water flow is essential for the sponge's feeding, respiration, and waste removal processes.

Trace the water route in the three types of canal system in sponges?
Sponges have three types of canal systems: asconoid, syconoid, and leuconoid. In the asconoid system, water enters through small pores called ostia, flows directly into a central atrium, and exits through a larger opening called the osculum. In the syconoid system, water enters through ostia, moves into incurrent canals, passes through radial canals lined with choanocytes for filtration, and then exits via the osculum. The leuconoid system, the most complex, features a network of interconnected chambers where water flows through incurrent canals, into choanocyte-lined chambers, and out through excurrent canals to the osculum, allowing for greater filtration efficiency.
What is the large opening at the top of the sponge?
Top opening of a sponge is called osculum . it is used to expel water out .
