Quiz Answer Key and Fun Facts

1. The sponge in the Porifera phylum is the simplest animal. They are mostly marine and lack cellular differentiation. Name the structure that provides support for them.

Answer: Spicule

Their spicules that are found in their matrices (the amoeboid layers found between the outer epithelial layer and the inner collar cells layer) are needle-like structures that provide support for sponges.

Answer: Zooxanthellae

Coral reefs provide carbon dioxide and inorganic materials for zooxanthellae in order for them to carry out photosynthesis. In return, zooxanthellae provide coral reefs with oxygen and products of photosynthesis. Both parties gain benefits from each other.

Answer: Cephalization

Platyhelminthes or flatworm is the simplest animal to show cephalization, which means that it possesses sensory organs and a brain in its head region.

4. Roundworms in the Nematoda phylum can cause serious disease to both human and animals. They are supported by?

Answer: Hydrostatic skeleton

Some examples of animals in this Platyhelminthes phylum are hookworms, heartworms (found in infected dogs' hearts), and pinworms. They are all supported by hydrostatic skeletons.

5. Animals in the Annelida phylum show segmentation, which is advantageous for their locomotion. Leeches (class Hirudinea) are associated with their well-known hirudin, which is a/an?

Answer: Anticoagulant

Leeches are bloodsuckers. Their saliva contains a type of powerful anticoagulant that prevents blood from clotting.

Answer: Antenna

In the head region, there are nerve cells and brain. On the other hand, locomotion and respiration occur in thorax, while abdomen carries out digestion and reproduction functions.

Answer: Cephalopoda

Most cephalopods are marine. Examples are squid, loligo and octopus. A closed circulatory is an advantage as it is more efficient than an open circulatory system, because in a closed circulatory system, the heart will separate the oxygenated and deoxygenated blood.

Answer: Reproduction

The gas exchange process occurs at ampullae. Besides, ampullae are used for locomotion (body movement) and food capture. Sea stars show bilateral symmetry in their larval stages; but radial symmetry in their adult stages.

Answer: Notochords

Mammalia is one of the 7 classes under the subphylum of Vertebrata. The other two subphyla are Urochordata and Cephalochordata. Other mammals' special characteristics are their hair, mammary glands and 3 bones in the middle ears.

Answer: True

Yes, that's us, with the scientific name of Homo sapiens. I hope you enjoy this quiz and learn something as well. Thanks for playing.
