Answer: Facultative anaerobe
Explanation: Facultative anaerobes are organisms that can live with or without oxygen supply. this organism processes carbohydrates and proteins as oxygen is taken away from its enviroment in order to derive oxygen.
Answer:
e) unicellular, colonial, or multicellular.
Explanation:
Protists originates from the Kingdom Protoctista. They comprise of organisms that are unicellular (Amoeba) or unicellular-colonial (volvox) in nature and which have no tisssues, therefore they are at the cellular level of organization.
Examples include, Amoeba, Paramecium, Euglena, Slime mold, Kelp, Diatoms, DInoflagellates. etc.
Some of them are also considered to be multicellular eukaryotes e.g slime molds, red algae etc. Eukaryotic organisms are organisms that possess cells containing a nucleus.
Characteristics in which protists exhibit varies from one species to the other.
For example, the mode of nutrition in eukaryotic algae are autotrophic in nature, in amoeba, they are gifted with pseudopods(false feets) in which they used to engulf prey(a term known as phagocytosis) therefore making them to be heterotrophic in nature.
In protist, locomotion varies from one organism to another. For example, in Amoeba , locomotion is achieved by extending and retracting pseudopods, Euglena are flagellated in nature , hence they move with the flagella. In Paramecium that are ciliated in nature, they move by propelling their cilia. etc.

Explanation:
Environmental exposure to certain chemicals, ultraviolet radiation, or other external factors.
Answer:
1.Pancreas 2.Pepsin
Explanation:
1.Esophagus and Large intestine are both parts of the alimentary canal.Alimentary canal is a part of the digestive system that moves along from mouth to anus.
2.Pepsin is an enzyme secreted by the stomach lining,basically the chief cells present in the epithellium of stomach Whereas Glucose is metabolized to glycogen and is stored for energy the body.Glycogen is formed by glycogenesis from glucose.
