1. A student is observing a cell under the microscope. It is observed to have supercoiled DNA with histones. Which of the following would also be observed by the student? a. A single circular chromosome b. A nucleus c. Free-floating nuclear material d. No organelles ANS: B The cell described is a eukaryotic cell, so it has histones and a supercoiled DNA within its nucleus; thus, the nucleus should be observed. A single circular chromosome called a prokaryote contains free-floating nucle...

Question 1 4 / 4 pts Multiple Choice: Which of the following signaling types occurs during periods of development specifically for the secretion of growth factors? Autocrine signaling Endocrine signaling Direct cell-to-cell signaling Correct! Paracrine signaling Synaptic signaling Question 2 4 / 4 pts Explain why a steroid hormone would require a carrier protein to transport it through the bloodstream. Answer: Steroid hormones are hydrophobic. They would require a carrier pr...

NBME Pathology verified 100% full solution Apoptosis: - ANSWER-Programmed cell death. REQUIRES ATP. Can occur via the intrinsic or extrinsic pathways, both of which involve activation of cytosolic caspases which mediate cellular breakdown. ***Unlike necrosis, apoptosis does not involve significant inflammation. Involves eosinophilic cytoplasm, cell shrinkage, pyknosis and basophilia, membrane blebbing and karyorrhexis, and formation of apoptotic bodies which are phagocytosed. **DNA ladderin...

Cytoplasm is a clear, thick gel containing carbohydrates, lipids, proteins and other chemicals that surrounds the nucleus in a cell. Homeostasis is the condition where internal and external environments remain constant and in balanceCe The Four Phases of Mitosis are? prophase, metaphase, anaphase, telophase Morphology is the description of the form and structure of tissues on the body Hypertrophy is an increase in the size of a tissue Atrophy is a decreas...

Histotechnology--Nuclear & Cytoplasmic Staining Question and answers already passed 2023/2024 c. nuclei *hemalum stains (hematoxylin mordanted with either ammonium aluminum sulfate or potassium aluminum sulfate) are used almost exclusively to stain nuclei Harris hematoxylin is used on tissue sections to stain: a. fat b. glycogen c. nuclei d. cytoplasm b. oxidation *can be done naturally (atmospheric oxygen), or with oxidizing agents Ripening of hematoxylin is a process of: ...

A - Alanine (1 letter) Activation of enzymes through ligand binding: why would this be useful? - The binding of a ligand to an allosteric site of a multimeric enzyme often induces positive cooperativity, that is the binding of one substrate induces a favorable conformation change and increases the enzyme's likelihood to bind to a second substrate. Ala - Alanine (3 letter) Arg - Arginine (3 letter) Asn - Asparagine (3 letter) Asp - Aspartic Acid (3 letter) Barr body and relation to hete...

Holocrine Glands - ANSWERentire cells are discharged as secretion (sebaceous glands) Merocrine glands - ANSWERsecrete product through free surface, no loss of cytoplasm/cell Apocrine Glands - ANSWERsecrete small amounts of cytoplasm/cell with secretory product (mammary glands) unicellular - ANSWERgoblet cells Multicellular - ANSWERtubular, alveolar/acinus Serous secretion - ANSWERclear, watery with protein Mucous secretion - ANSWERcloudy, mucin (glycoproteins) with water Com...
