Can somebody explain this to me please A sequence of ATTCATTA undergoes duplication during mutation resulting in a
sequence of ATTCACATTCA

What substance has a mass of 9.5g and volume of 2.1cm^3

The small bags of silica gel you often see in a new shoe box are placed there to control humidity. despite its name, silica gel is a solid. it is a chemically inert, highly porous, amorphous form of sio2. because water vapor readily adsorbs onto the surface of silica gel, it acts as a desiccant. despite not knowing mechanistic details of the adsorption of water onto silica gel, from the information provided you should be able to make an educated guess about the thermodynamic characteristics of the process. predict the signs for δg, δh, and δs for the adsorption of water.

If an atom has 12 protons and 13 neutrons
