Unlike weather, climate a. describes the day-to-day condition of the atmosphere of earth. b. describes the average conditions and atmospheric patterns of a region over time. c. involves variations in precipitation. d. involves variations in temperature

Climate describes the average conditions and atmospheric patterns of a region over time. Weather and climate are both used interchangeably but they differ in the length of time they are measure and how specific trends affect them over specific periods.

Climate includes describing precipitation, temperature, and humidity for longer periods; whereas, weather includes sunshine, rain, and thunderstorms. Usually weather statistics to learn about climate would range from 30 years of observation while weather considers more the real-time measurements of events like cloud cover or rain that one commonly sees in weather forecasts on the television.  

When a virus infects a host cell, it uses the cell's machinery to make copies of its own genetic material in a process called replication. finally, during the process of self-assembly, that protein shell and the copies of the virus's genetic material are assembled into new viruses.
