Not every relation is a function. But every function is a relation. Function is just a part of relation.
The cubic function.
Range
A formula or graph are two ways to describe a math function. How a math function is described depends on the domain of the function or the complexity of the function.
The Mandelbrot graph is generated iteratively and so is a function of a function of a function ... and in that sense it is a composite function.
spongin and spicules are the sponges body support and defence
Spongin provides structural support in certain marine sponges by forming a flexible, protein-based skeleton. Spicules are tiny, needle-like structures made of calcium carbonate or silica that also provide structural support and protection in sponges, as well as help deter predators.
No, spongin is made of a scleroprotein and not silica spicules. Silica spicules are found in the skeletal structure of some sponges, providing structural support. Spongin is a fibrous protein that also helps provide structural support to certain types of sponges.
Spongin A+
spongin!
A network of spongin or spicules.
Spongin and spicules are the sponges body support and defence. They both cover a sponge, and if a predator eats it it will be hurt. It will be hard to eat it, because of the sharpness and roughness of the outside. Well at least in the spicules case.

Yes, a flexible network of protein fibers called spongin provides structural support within a sponge's body. This network helps maintain the sponge's shape and allows for water flow and nutrient exchange through its pores.
1. spicules (calcium carbonate or silica) 2. spongin (protein)
This answer is unlimited. All sponges are different sizes, and each species has variations on the number of pores. Sponges are only made of spongin, a network of webbed collagen. Pores are only gaps in the spongin where water is forced through. As you may already know, squeezing a sponge expels the water from all locations of the sponge. Therefore, water can travel through all parts of the sponge. You may consider every gap in the spongin to be a pore. This number cannot be recorded, as it varies greatly throughout all sponges.
Spongin is a tough, fibrous protein that provides structural support to sponges, making them difficult to consume. Spicules are tiny, needle-like structures made of calcium carbonate or silica that can be sharp and harmful if ingested by predators. Together, these structures make sponges unpalatable and unattractive to most predators.
