Just finshed it on a test. Sponges lack a digestive track, symmertical plan, and nerce cells.
Explosive Used For Fire-lanceGun powder was used by the Chinese to make explosives and the primitive flamethrower called a fire-lance.
They never did make hieroglyphs simpler - in fact during the Late period, hieroglyphs became more complex and difficult. Continuing the traditional form of writing over 3,000 years was a sacred duty for Egyptian priests and scribes; anything else would have been an insult to their gods.
lack if respect Lack of respect for the Patriot soldiers.
That's what computers were designed to do...process data...make our live simpler.
There is one main characteristic of a state that the 50 states lack. That characteristic is sovereignty, which would make them completely independent.
Sponges are classified as animals because they are multicellular, heterotrophic organisms that lack cell walls. They also have specialized cells and tissues, even though they lack complex organ systems.
A primitive life form like mold or yeast that cannot make their own food is referred to as a heterotroph. These organisms rely on external sources of organic matter for nutrition, as they lack the ability to produce their own through photosynthesis or chemosynthesis. Instead, they break down complex organic molecules into simpler forms that they can absorb and use for energy.
Sponges were first though to be plants because, at first glance, they appear to be so. They are immobile, have no appendages to speak of, and lack a nervous and circulatory system. What sets them apart from plants, however, are two main things. The first being that they are filter feeders; they siphon water through their bodies and specialized cells with cillia catch the food and transport it to speceialized cells to be digested, whereas the vast majority of plants make their own food. The second is that most sponges start out as free-swimming larvae that eventually settle down onto a solid surface and transform into the sessile soft-bodied creatures we know as sponges.

Sponges lack muscle cells for movement, while cnidarians lack a skeletal structure for support and protection. Without these features, these organisms are limited in their ability to achieve a more mobile lifestyle compared to animals with more specialized adaptations.
No, sea sponges can not make their own food. They obtain their nutrition from the food particles in the water. Sponges primarily eat bacteria, phytoplankton, and other small food bits out of the water.
Sponges
poke a hole in it
They make nothing,except growing arms when their arm break.
sponges have a large amount of air spaces in between them. When we squeeze them, the air is expelled out & after releasing the pressure the air reenters helping it to regain its original shape. The presence of air spaces make sponges compressible.
It would make no difference
They die alone in little houses.
