Animal cells contain dna enclosed in the nucleus
The higher the number of cells getting wired together in a photo-voltaic cell, the higher its electricity or energy yield would be. In addition, the primary function of a PV panel is to convert light energy from the sun directly into electrical energy in a form of voltage that could be used by electricity-consuming devices.
You can gather information from both actions.
I believe A is the most correct (i assume it's about antibiotics - they actually DO harm our immune system in some way).
B is partially correct because, the colds indeed should be treated by anti-viral medication (because the virus is a cause of typical cold) but using antibiotics during recovery is needed only when an additional bacterial infection occurs as a complication after the viral infection. and it doesn't happen very often.
C - what works? antibiotics doesn't work for viral infections (colds). anti-viral medication do.
D i won't discuss.
I am sorry for a so long answer. but your question is so linguistically twisted that i am not sure which of the following choices is actually correct because of a big amount of mistakes.
