Answer

Answer:

A. All of these are characteristics of non - chordates.

Brief Explanations:

  1. For "They have some form of symmetry": Most non - chordate organisms (like sponges which are non - chordates have asymmetry, but many others like cnidarians have radial symmetry, and worms have bilateral symmetry) have some form of symmetry.
  2. For "They are capable of movement at some point in their life": Even sessile non - chordates like some sponges or corals may have larval stages that can move, and most non - chordates can move at some life stage.
  3. For "They have tissues": Most non - chordate animals (except sponges which are parazoans) have tissues, and when considering the broad group of non - chordates (including non - animal non - chordates like some protists? No, non - chordates here are mainly non - chordate animals. But in the context of animal non - chordates, most have tissues. Since the option "All of these" includes the valid characteristics, it is the correct answer.
