B. gastrovascular cavity
C. complete digestive tract
D. complete digestive tract and a gastrovascular cavity
E. incomplete digestive tract and a gastrovascular cavity
The CORRECT ANSWER IS E.
E. incomplete digestive tract and a gastrovascular cavity
Explanation:
Phylum Cnidaria; Cnidarians are diploblastic with two embryonic germ layers -the ectoderm and the endoderm) with well structured tissue, performs extracellular digestion, and use cnidocytes for defence and to catch prey.
Cnidarians have two unique morphological body plans which are referred to as polyp, its sessile in adults, and medusa are mobile; some species has both body structures in their lifecycle.
It undergo extracellular digestion, where enzymes dissolve the food substances as its cells lining the gastrovascular cavity take in the nutrients.
Cnidarians are known to have a body arrangement of incomplete digestive system with just one opening; the gastrovascular cavity that functions as both a mouth and an anus.
The cnidarians undergo extracellular digestion, the food is moved to the gastrovascular cavity, enzymes are present in the cavity, with the cells lining the cavity taken in nutrients. The gastrovascular cavity possess a singular opening that acts as a mouth and an anus; this is referred to as an incomplete digestive system.
Answer;
-ATP
Explanation;
-ATP is the main source of energy for most cellular processes. The building blocks of ATP are carbon, nitrogen, hydrogen, oxygen, and phosphorus. Because of the presence of unstable, high-energy bonds in ATP, it is readily hydrolyzed in reactions to release a large amount of energy.
-The enzymatic removal of a phosphate group from ATP to form ADP releases a huge amount of energy which is used by the cell in several metabolic processes as well as in the synthesis of macromolecules such as proteins. The removal of a second phosphate group from ATP results in further energy release and the formation of adenosine monophosphate (AMP).

ATP hydrolysis is the catabolic reaction process by which chemical energy that has been stored in the high-energy phosphoanhydride bonds in adenosine triphosphate (ATP) is released by splitting these bonds, for example in muscles, by producing work in the form of mechanical energy. The product is adenosine diphosphate(ADP) and an inorganic phosphate, orthophosphate (Pi). ADP can be further hydrolyzed to give energy, adenosine monophosphate (AMP), and another orthophosphate (Pi).[1] ATP hydrolysis is the final link between the energy derived from food or sunlight and useful work such as muscle contraction, the establishment of electrochemical gradients across membranes, and biosynthetic processes necessary to maintain life.
The description and typical textbook labeling anhydridic bonds as "high energy . . bonds" can be very misleading to students. These bonds are in fact relatively weak. They do involve high energy electrons but the bonds themselves are quite easy to break. As noted below, energy is released by the hydrolysis of ATP when these weak bonds are broken – requiring a small input of energy, followed by the formation of new bonds and the release of a larger amount of energy as the total energy of the system is lowered and becomes more stable.
