1) Which of the following statements about the properties of life is false? A) All organisms have the ability to take in energy and use it.
B) All organisms have the ability to respond to stimuli from the environment.
C) All organisms have the ability to reproduce.
D) All organisms have the ability to maintain a constant internal temperature.

D

Explanation: Because organisms such as snakes are unable to do this, because they are cold-blooded

organisms that lack symmetry are called asymmetrical and belong to phylum porifera/sponges.

organisms with specialized stinging cells belong to phylum cnidaria. stinging cells are called cnidoblast cells.

cnidarians show two morphological forms : polyp (sessile) and medusa (mobile)

filter feeding is observed in porifera members.  

alternation of generation is observed in coelenterata or cnidaria. there is alternation of asexual polyp form and sexual medusoid form. it is also referred as metagenesis.
