BIO 172 UH Manoa Exam 2 Latest 2025
Questions and Answers Graded A+
Animals - CORRECT ANSWER-Multicellular eukaryotes
Heterotrophs: Ingest their food
Lack Cell Walls
Body held together by structural proteins
,Phylum: Nematoda - CORRECT ANSWER-Nematodes are everywhere and
parasitize everything

films on mosses or marine sands, feed on plants, nematodes.
Exhibit cryptobiosis: State of suspended metabolism
Phylum: Arthropoda - CORRECT ANSWER-Cuticle hardened by proteins and
the carbohydrate chitin to form an exoskeleton
Segmented body is divided into functional groups called tagmata
Trachea: System of Respiration air canals
