TUESDAY, January 7 2018-IN CLASS (a) is defined as all the genes being used to make protein. (b) contains all of a cell's DNA (e) constantly changes, depending upon the cell's env (d) is altered during embryonic development. 7 What unit of length would you generally use to measure a (a) centimeters (b) nanometers (c) millimeters (d) micrometers typical plant or animal cell? 8 Cell biologists employ ta geted fnuorescent dyes or modified fuorescent proteins in both standard flu in the orescence microscopy and confocal microscopy to observe specific detai same as that of a standard light microscope because the resolving power of a microscop ven though fluorescence permits better visualization, the resolving power is esse we limited by theof light. (a) absorption (b) intensity (c) filtering (d) wavelength 9 What is the smallest distance two points can be separated and still resolved using light microscopy? (a) 20 nm (b) 0.2m (c) 2 um (d) 200 m 10 Although there are many distinct prokaryotic species, most have a small range of shapes, sizes, and growth rates. Which of the following characteristics are not observed in prokaryotes? (a) DNA (b) endoplasmic reticulum (c) (d) the ability to divide rapidly a cell wall Prokaryotic cells are able to evolve very fast, which helps them to rapidly adapt to new food sources and develop resistance to antibiotics. Which of the options below lists the three main characteristics that support the rapid evolution of prokaryotic populations? (a) microscopic, motile, anacrobic 11 acrobic, motile, rapid growth no organelles, cell wall, can exchange DNA large population, rapid growth, can exchange DNA (b) (c) (d) is made up of two concentric membranes and is continuous with the The membrane of the endoplasmic reticulum. (a) plasma membrane (b) Golgi network (c) mitochondrial membrane 12Explanation / Answer
