Can you infect your dog with COVID-19

The pathway for arginine biosynthesis in Neurospora crassa involves several enzymes that produce a series of intermediates as shown. O O O O ornithine citrulline ARG-E arginosuccinate arginine N-acetylornithine arginine You did a cross between ARG-E ARG-H* and ARG-E* ARG-H¯¯ Neurospora strains and identified an Arg- strain from an NPD tetrad. (Assume that Neurospora forms tetrads in the same way yeast do.) Which compound would rescue growth of this Arg- spore? N-aceltylornithine ARG-F ornithine citrulline ARG-G ARG-H → argininosuccinate

A two mL stock of Marburg virus (Filamentous, non-segmented, negative strand RNA virusin Filoviridae family) contains 5.6 x 1017 virions (individual viruses)/mL. The sample mustbe diluted serially to the point in which 2.4 x 106 virions exist in every 100 µL of sample foran infection experiment which requires at least 7.2 mL (you will NEED more than 6 mL).Using dilutions of no greater than 1/1000 in volumes no greater than 10 mL and includingone dilution of 1/8.8 show below how you would set up this dilution series. Remember smallvolumes carry inherently larger error.

Can someone help me with my virology homework? Can you explain how to interpret these three figures?

Which of the following is in the correct order heme --> biliverdin --> bilirubin --> urobilins heme --> bilirubin --> biliverdin --> urobilins biliverdin --> heme --> bilirubin --> urobilins biliverdin --> bilirubin --> transferrin --> urobilins Ood

Human cells contain a protein that binds to the 5′ triphosphate groups of RNA. Explain why this protein would be part of the defense against viral infection.
