Mice (mus musculus) have 40 chromosomes per diploid cell (2n = 40). how many double- stranded dna molecules and how many chromosomes are there in a mouse cell that is in the g2 stage of the cell cycle?

Photosynthesis uses co2 and cellular respiration produces co2. we call the point when the two processes are in balance--when there is no net production of co2--the compensation point. how might you limit one of the processes in order to achieve a compensation point?
