The same as a pig but not goats
a sponge does not have a nervous system
The sponge.
Bisconoid
A sponge is one animal that has no hair, mouth, or ear. In fact, the sponge has no muscles or nervous system, either.
Bilaterally symmetric animals have a central nervous system.
Not all animals have complex nervous systems. In fact, most lower animals don't even show an organized nervous system. Its only in higher animals like chordates that a proper organized nervous system is seen.
A sponge is a porous aquatic animal with a soft, squishy texture. It lacks organs and a nervous system, and is usually found attached to a surface in marine environments.
segmented
Amphetamines are stimulants of the central nervous system and sympathetic division of the peripheral nervous system.
A mountain lion's nervous system is the same as for any other mammal.
No, a sponge is not considered alive in the biological sense because it lacks organs, tissues, and a nervous system. Sponges are simple multicellular organisms that rely on filtering water to obtain nutrients and oxygen.
Sponges are animals and are heterotrophs- they need to take in nutrients and food for energy. The nutrients are carried by the water into the sponge.
