Nucleus - contains genomic content in eukaryotic cells Endoplasmic reticulum - series of membrane enclosed sacs and interconnected tubes Lysosomes - contain hydrolytic enzymes for digestion Chloroplast - Site of photosynthesis Briefly explain how a Scanning Electron Microscope (SEM) forms an image of a microscopic specimen. - Answer: An image is formed from the interactions of electrons as they reflect off (not through) the surface of the specimen. Samples are coated in either gold or pall...

True or False: viruses can be classified as prokaryotic or eukaryotic - False. Viruses are neither prokaryotic or eukaryotic What is an obligate intracellular parasite? - viruses cannot replicate unless inside a living host cell. As a parasite, a virus depends on its living host to provide the framework (proteins, etc) to replicate—to make additional copies of itself. What is a viral capsid? - a membrane-like protective structure that contains genetic material similar to nucleus of eukar...

What is matter? - Anything that takes up space, has volume and mass What is autophagy? - When cellular organic matter is broken down and recycled into new biomacromolecules States of matter - Solid, liquid, gaseous (vapor), or plasma What is all matter made of? - Elements What are essential elements? - Elements required for human life What are trace elements? - Elements required only in small quantities How are molecules formed? - When elements combine with one another What is formed if ...

What is cellular metabolism? - a controlled set of biochemical reactions that occur in living organisms in order to maintain life. What is the primary function of enzymes and how are they regulated? - Enzymes speed up chemical reactions. Most notably, the enzyme is not consumed during the reaction and can be used repeatedly by the cell. Enzymes can also be regulated by a cofactor such that in the absence of the proper cofactor, enzymes are inactive while in its presence enzymes are active. ...

Three days after surgery, a male client suddenly grabs his right chest and becomes short of breath, pale, and diaphoretic. The practical nurse (PN) immediately assesses his vital signs and obtains 100/80 mm Hg blood pressure, 110 beats/min heart rate, and 36 breaths/min respiratory rate. What action is most important for the PN to take next? - Apply oxygen at 2 liters per nasal cannula. An elderly female client with dementia is transferred from a long-term care unit to an acute care unit. ...
