How do sponges remove nitrogenous waste?
Sponges remove nitrogenous waste through a process called diffusion. The waste molecules passively move out of the sponge cells and into the surrounding water, where they are eventually carried away. This allows sponges to efficiently get rid of metabolic waste products from their body.
Why do sponges not need a fluid transport system?
Because sponges have seawater to carry nutrients and waste.
How are water and waste materials removed from the sponges body?
Osmosis
Can sponges only live in water?
the answer is "yes" because sponges are attached to hard surfaces underwater, and they are well adapted to their watery life. moving water currents carry food and oxygen to them and take away the sponges' waste products.
What are four characteristics shared by sponges and humans?
Both humans and sponges are made of millions of cells, both need oxygen to survive, both need water and both produce waste products.
Are sponges heterotrophs?
Sponges are animals not plants and they consist of an outer thin layer of cells and a inner mass of cells. Sponges do not have nervous, digestive or circulatory systems, instead they rely on maintaining a constant flow of water going through their bodies to obtain food, oxygen and to remove waste products. There are 9000 known species of sponges known and about 80% of them are saltwater , the lowest depths of some species of sponges are 8,800 m (5.5mi).
When magma squeezes between horizontal lines it forms?
if it squeezes into a fault, its a dike, if it squeezes between horizontal layers, its a sill
What function does water perform for sponges?
Water provides structural support to sponges, helping them maintain their shape and enabling them to filter food particles from the water passing through their pores. In addition, water carries oxygen and nutrients to the cells of the sponge and helps in waste removal.
How do sponges carry out essential body functions?
Sponges carry out essential body functions through simple diffusion. They do not have a circulatory, respiratory, or digestive system. Nutrients and oxygen diffuse directly into their cells from the surrounding water, and waste products are expelled in the same way.
Why are sponges used instead of paper towels in a lab?
I'd guess that sponges are less reactive with strong acids. You also mention waste and recycling. Paper towels are often used once, then thrown in a garbage can that is typically outside of a fume hood. It would be a good way to noxious chemicals released into lab, as well as potentially bringing incompatible chemicals together. Sponges can be rinsed, and thus would be less likely to bring incompatible chemicals together in a waste can. Will create less waste, and won't sit around releasing fumes into the room. Finally, it will be safer for the janitors and everyone else involved in the waste stream.
Sponges can be classified as?
Sponges (poriferans) are very simple animals that live permanently attached to a location in the water - they are sessile as adults. There are from 5,000 to 10,000 known species of sponges. Most sponges live in salt water - only about 150 species live in fresh water. Sponges evolved over 500 million years ago. The body of this primitive animal has thousands of pores which let water flow through it continually. Sponges obtain nourishment and oxygen from this flowing water. The flowing water also carries out waste products.
Sponges eliminate carbon dioxide and cellular wastes by?
Sponges eliminate carbon dioxide and cellular wastes through diffusion. As water flows through their pores, oxygen and nutrients are absorbed, while waste products are released into the surrounding water. Sponges do not have specialized organs for excretion, relying instead on passive diffusion.
