First, a complete digestive system means that the digestive tract has a beginning or the oral end and the opposite end or the aboral end. This is found in more complex animals starting from roundworms (flatworms have an incomplete digestive tract). A closed circulatory system is found in animals more recent than mollusks. The presence of the coelom makes it more evolved than the flatworms.
Specifically, a small animal with a segmented body, short stiff appendages, and soft skin with the above characteristics point out to the phylum Annelida or annelids.

B, element
a molecule would require more than one atom. if one atom is left and is still gold, it would not be a molecule/mixture/compound.
Explanation:
The synthesis of carbon dioxide and water is purely catalyzed by light energy from the sun. The light energy is used to synthesize useful organic molecules and produce oxygen gas.
- Photosynthesis is light catalyzed.
- Green plants manufacture their food using sunlight.
- A special pigment in plant called chlorophyl traps the sunlight.
- Carbon dioxide and water will react when the light energy from the sun is made available in plant leaves.
- This will then produce organic compounds with rich chemical energy.
- Oxygen gas is given off as a by product.
