What else can I help you with?
The trend toward cephalization is first seen in the?
nematodes!!
A concentration of sense organs and nerve cells in anterior end of the body known as?
Cephalization
Which invertebrate phyla was first to show cephalization?
Platyhelminthes
Does a hydra have cephalization?
A hydra does not have cephalization.
Annelids show what by having bilateral symmetry?
cephalization for segmented worms, but idk about anything else
What is the cephalization of a mollusca?
The cephalization of a mollusca could possibly describe the arrangement of neurons in the front end of the animal.
What invertebrate group was the first to show cephalization?
The first invertebrate group to exhibit cephalization was likely the flatworms (phylum Platyhelminthes). Cephalization is the evolutionary process of concentration of sensory structures (such as eyes and other sense organs) and nervous tissues at the anterior end of an organism, forming a head region.
What does annelids show by having bilateral symmetry with an anterior head where most sense organs are found?
Cephalization
List the phyla that show cephalization?
The phyla that show cephalization include Chordata (which includes vertebrates), Arthropoda (including insects, crustaceans, and spiders), Annelida (segmented worms), and Mollusca (which includes snails, clams, and octopuses).
Are Cnidarians in cephalization?
Cephalization means formation of a head. Cnidarians have no head, so no.
How do animals with cephalization respond differently to the environment than animals without cephalization?
Animals with cephalization respond more quickly and in more complex ways.
What cephalization does a platyhelminthes have?
Platyhelminthes show the simplest form of cephalization among animals. They have a concentration of sensory organs and nerve cells at the anterior end of their body, which forms a head-like structure. This allows them to detect and respond to stimuli efficiently.
