No a worm is more complex than a jellyfish
No, it doesn't have six legs or more so it can't possibly be an insect.
The structures of a flatworm and a earthworm are different by the way the are shaped. The earthworm is the one that looks like a regular worm it is more rounded and a flatworm looks like leeches.
the brain is essential for the movement of the earthworm. If the brain of the earthworm is removed, the earthworm will move continuously without stop
Yes, an earthworm is a decomposer.
The earthworm's crop and gizzard feel different because they perform two different functions. The gizzard is hard to the touch because it is used to grind the soil the earthworm takes into its body. The crop is soft and more saclike because it stores food that the earthworm separates from the other things it takes in.
Group one (earthworm, spider, jellyfish) are more distantly related compared to group two (frog, trout, centipede) because group two share a more recent common ancestor. This is because frog, trout, and centipede are all part of the same phylum Chordata, whereas earthworm, spider, and jellyfish are part of different phyla (Annelida, Arthropoda, and Cnidaria, respectively).
jellyfish
An invertabrae are animals with no backbone. Most the earths animals hve no backbone! Some examples are: * squid * shark * jellyfish * earthworm and lots more!!!
A human nervous system is much more complex. Unlike a human a jellyfish does not have a central nervous system.
All living organisms have a very complex chemistry.
The earthworm like many more complex organisms has a closed circulatory system, meaning that its blood is confined to blood vessels and its blood is recirculated so it gets maximum use
Yes, all more complex life forms have many cells. The opposite to a multicell is single cell.
Jellyfish have Radical Symmetry and Cnidaria (Latin for "stinging cells") Also, they have two cell layers that are organized into tissue. Cnidaioans hace digestive,muscle,nerve, and sensory tissue. The Cnidarian body is a hollow sack with only ONE body opening (a mouth). It is surrounded by rope-like pieces of tissue called tentacles (arms). These tentacles may contain stinging cells. Hope that helps.
it was here before the dinos and was the most complex thing in the millions B.C
Yes. An earthworm is a multicellular organism and has many more than one cell.
An earthworm is a multicellular organism, therefore it has many more than one cell.
Jellyfish have a simple digestive system. They have a digestive cavity with cells lining the wall that carry out the digestive function.
