Which of the following among A-D is false concerning animal viruses? A) During the courses of an influenza virus infection, flu virus proteins are likely to be found in the nucleus, host cell membrane, and cytosol. B) The type of life cycle an animal virus possesses is mostly determined by its genome type C) Lambda phage can form a prophage; an equivalent animal virus type like this would be a retrovirus D) Interferons are produced by certain hosts to defend against animal viruses E) None of A-D is false; all are true

E. None of A-D is false; all are true

Explanation: virus protein are most likely to be found in nucleus, cytosol and host membrane during the cause of an influenza because the virus first penetrate the cytosol before it RNA are transported to the nucleus where transcription and replication of the viral RNA occurs. Every other option is correct

cells use diffusion to get substances in and out of themselves. that diffusion will occur across the cell membrane or the outer covering of the cell. because we are talking about the surface of the cell, surface area and volume are  important factors here. as a cell increases in size, its surface area and volume increase as well.  we call that the surface area to volume ratio (sa: vol).  but the catch is that  volume increases at a greater rate than surface  area. in other words, as a cell gets bigger, the sa: vol gets smaller. so a really small cell like bacteria is mostly cell membrane (surface) with very little contents (volume). a really big cell like an egg, is mostly insides with a super thin membrane. so what ends up happening is that the cell cannot efficiently diffuse all of the stuff it needs in/out to survive. therefore cell size is limited to about 100mm. so how do we make organisms bigger than 100mm? cells divide! by dividing and becoming multicellular, organisms are able to grow!   check out the diagrams i attached to see the effect of sa: vol. i hope this ! good luck!
