Explain the flow of energy to the lamp from electrical energy. A. Electrical energy from the plug is used to make electromagnetic energy in the form or light. B. Electrical energy from the plug is converted into mechanical energy in the form or light and thermal energy in the form of heat. C. Electrical energy from the plug is converted into electromagnetic energy in the form or light and thermal energy in the form of heat. D. Electrical energy from the plug is converted into electromagnetic energy in the form or light and the remaining energy is lost as heat.

Which of the following best reflects what we know about how the flu virus moves between species? a) the flu virus in a pig is mutated and replicated in alternate arrangements so that humans who eat the pig products can be infected.b) a flu virus from a human epidemic or pandemic infects birds; the birds replicate the virus differently and then pass it back to humans.c) an influenza virus gains new sequences of dna from another virus, such as a herpesvirus; this enables it to be transmitted to a human host.d) an animal such as a pig is infected with more than one virus, genetic recombination occurs, the new virus mutates, the virus is passed to a new species such as a bird, and the virus mutates again and can now be transmitted to humans.
