Well, to be fair, this is a bit of a tough question because it's in question by some of the leading microbiologists right now.
But one argument for this is their ability to reproduce. Note that one of the leading arguments for something to be alive is that they are subject to evolution and hence natural selection: the statements for which argue that there has to be differentiation within a species (meaning there has to be different forms of each virus within a type of virus) and there has to be reproduction-- which is where the problem comes along (because viruses could only reproduce while in a host). So one argument that can be made that they are in-fact alive, is that they reproduce and is subject to evolution.
Do know however that this is HIGHLY controversial-- and if your teacher asks it, it's most likely not a right-or-wrong answer
If he does do it that way, maybe you could show off your brainy-bio knowledge by explaining to him why it shouldn't be so!

The correct answer is A the rods in our eyes are sensitive to the exact wavelengths of the light
A parent cell, through mitosis, will create daughter cells with the same number of chromosomes as it has (diploid)
Solution:
The series of processes by which carbon compounds are interconverted in the environment, involving the incorporation of carbon dioxide into living tissue by photosynthesis and its return to the atmosphere through respiration, the decay of dead organisms, and the burning of fossil fuels. And the oxygen cycle is a biogeochemical cycle that describes the movement of oxygen within the earth's three main reservoirs which are the atmosphere (air), the hydrosphere (water), and the lithosphere (land).
Both mix in one cycle because of these:
The C2 oxidative photosynthetic carbon cycle plus the C3 reductive photosynthetic carbon cycle coexist. Both are initiated by Rubisco, use about equal amounts of energy, must regenerate RuBP, and result in exchanges of CO2 and O2 to establish rates of net photosynthesis, CO2 and O2 compensation points, and the ratio of CO2 and O2 in the atmosphere. These concepts evolved from research on O2 inhibition, glycolate metabolism, leaf peroxisomes, photorespiration, 18O2/ 16O2 exchange,CO2 concentrating processes, and a requirement for the oxygenase activity of Rubisco
