C. ANNELIDS

D. PORIFERA

The common name of the group to which the organism belongs to cnidarians.

Cnidaria is a phylum under kingdom Animalia containing over 11,000 species of aquatic animals found both in freshwater and marine environments, predominantly the latter. Their distinguishing feature is cnidocytes, specialized cells that they use mainly for capturing prey.

Moreover, cnidarians have a unique feature: stinging cells called cnidocytes (NID-uh-sites). Each cnidocyte cell has a long, coiled, tubular harpoon-like structure.

Hence, the phylum Cnidaria is made up of four classes: Hydrozoa (hydrozoans); Scyphozoa (scyphozoans); Anthozoa (anthozoans); and Cubozoa (cubozoans).

9. Doctors tested a patient to find out what molecules were in her cells. Her cells contained normal levels of oxygen molecules, low levels of amino acid molecules, and low levels of glucose molecules. Will this patient be able to exercise normally?

A. Yes, as long as her cells have enough oxygen, her body will be able to exercise.
B. No, her cells need glucose to react with oxygen to release enough energy to exercise.
C. No, her cells need amino acids to react with oxygen to release enough energy to exercise.
D. No, her cells need glucose to react with amino acids to release enough energy to exercise.

10. Asthma is a condition in which it can be very hard for a person to breathe in enough air. Would it also be difficult for someone with asthma to exercise?

A. No, as long as the person is getting enough sleep, he will make enough energy to exercise.
B. No, as long as the person's cells are getting different types of molecules from food, he can still exercise.
C. No, the person's cells may not have everything they need, but his body can still exercise normally.
D. Yes, it will be difficult for a person with asthma to exercise because his cells need molecules from air.

11. Jamal ate a meal of rice before seeing his doctor. Rice is made of mostly starch molecules. Jamal has been feeling tired a lot, so his doctor gave him a test that found that Jamal’s cells contained normal levels of oxygen and low levels of glucose. Does this explain why Jamal has been feeling tired?

A. Yes, Jamal's respiratory system is working, but his digestive system is not turning the oxygen into glucose.
B. Yes, Jamal's respiratory system is working, but his digestive system is not breaking down starch molecules into glucose for his cells.
C. Yes, Jamal's digestive system is working, but his respiratory system has too much oxygen, so his body stopped making energy.
D. No, something else must be wrong with Jamal because his cells have all the molecules they need.

12. A patient has been eating healthy foods, but her respiratory system is not working as well as it usually does. Can this patient still exercise normally?
