A. Lysosome B. Rough Endoplasmic Reticulum C. Smooth Endoplasmic Reticulum D. Centriole Cells: organelles, membrane transport, microscopy basics

Start your revision early, stay curious, and remember: in biology, every "wrong" answer is just an opportunity to discover how life works.

Windows systems only.

 

9.�� COMPUTER SOFTWARE REQUIREMENTS

Users must purchase and install the MCNP package so the Visual Editor has access to the cross sections. Included in this distribution are two material files based on PNNL-15870 Rev1. (stndrd.n and stndrd.p). The Visual Editor can read these files if they are in the same directory as input file or if they are placed in a �VISED� directory that is at the same level as the MCNP_DATA directory (i.e. c:\mcnp6\vised, if you installed mcnp6© in c:\mcnp6). All versions of the Visual Editor must have access to the DATAPATH for accessing the cross sections. You can either run the Visual Editor within the MCNP6© command prompt (just type the executable name) or define the DATAPATH environment variable for your computer (computer->properties->advanced system settings->environment variables). Details on how to do this can be found on the website here: http://www.mcnpvised.com/HelpAndSupport/HelpAndSupport.
