Characteristics of Dysplasia - ANSWER-Loss of uniformity of cell size and shape = pleomorphism, Loss of tissue orientation, Nuclear changes - increase nuclear:cytoplasmic ratio and clumped chromatin Reversible cell changes to injury - ANSWER-Cellular and mitochondrial swelling due to reduce ATP leading to reduce activity of Na/K and Ca pumps, Membrane blebbing, Nuclear chromatin clumping, Ribosomal / polysomal detachment (reduced protein synthesis). Irreversible cell changes to ...

Microbiology Fundamentals: A Clinical Approach, 2nd ed. by Cowan Chapter 3 Prokaryotes v. Eukaryotes Correct Answer- -Prokaryotes' DNA is packaged differently - lack of nucleus & histones -Prokaryotes' cell wall is different - peptidoglycan & other unique chemicals -Prokaryotes' internal structure is different - lack of membrane-bound organelles Archaea Correct Answer- - More closely related to the Eukarya than Bacteria. - Often able to exist in extreme environments. - Adapted to gr...
