. 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? 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 is characteristic of prokaryotic cells, which do not have histones. Free-floating nuclear material describes a prokaryotic cell, which would not h...

Which of the following is NOT a part of the body's chemical defense system against infection? a. Urine b. Hydrochloric acid c. Agranulocyte d. Lysozyme (Ans – - Agranulocytes Agranulocytes are a type of white blood cell and therefore are not a part of the body's chemical defense system. Which of the following is considered an example of naturally acquired passive immunity? a. Attenuated (live) vaccine injection b. Breastfeeding c. Inactivated (killed) vaccine injection d....

USABO EXAM QUESTIONS AND ANSWERS Eukaryote - ANS An organism whose cells contain complex structures enclosed within membranes. The defining membrane bound structure that sets them apart from prokaryotic cells is the nucleus or nuclear envelope within which the genetic material is carried. All large complex species are eukaryotes, including animals, plants and fungi. Euchromatin - ANS This shows as pale areas in the nucleus under electro magnification. It is a less densely packed for...

Endosymbiosis Ans: Organelles originated when a single-celled organism engulfed another single-celled organism • Usually obligate: the survival of one depends on the other the process in which unicellular organisms engulf other cells, which will then function as organelles within the host cell. Studies of DNA sequencing suggest that green and red algae developed when heterotrophic eukaryotes engulfed cyanobacteria. Algae Ans: -Eukaryotic • Aquatic • Photo-autotrophs • Unice...

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 nuclear...

T/F: According to the module, a compound with a molecular mass of 1,000 g/mol is considered a macromolecule. Ans- false macromolecule >5,000 g/mol T/F: Biomolecules can have two or more different functional groups. Ans- true T/F: The following group is an amine. C2H5NH2 Ans- true T/F: In a eukaryotic cell, the organelles called peroxisomes serve the purpose of digesting macromolecules. Ans- false peroxisomes degrade dangerous/hazardous molecules, lysosomes degrade macromolecul...
