Nervous Tissue - Answer Neurons: specialized to receive stimuli and conduct wave excitation/impulses to all parts of the body. cell body: contains the nuclei and most of the organelles cytoplasmic projections: dendrites & axon Neuroglia/Glial cells: support, protect and bind neurons. Parts of Neurons - Answer Cell body

viroid - infectious agent consisting of a small circular RNA molecule that lacks a protein coat. Thought to cause disease by interfering with the cell's normal path of gene expression Common features between PROK and EUK (9) - PM, genetic info (DNA), similar mechanisms for transcription/translation, shared metabolic pathways (glycolysis, TCA), ATP, photosynthesis mechanisms, protein synthesis, proteasomes, cytoskeletal filaments built of proteins similar to actin and tubulin What are the 3...

Parasitism - Correct Answer-A symbiotic relationship in which one animal, the host, is injured through the activities of the other animal, the parasite. Parasites of medical significance belong to four phyla - Correct Answer-Protozoa, Platyhelminthes, Aschelminthes, and Arthropoda.
