Following statements are regarding to the molecular basis of the coincidence model in Arabidopsis.

A. In Arabidopsis under short days, there is little overlap between CO mRNA expression and daylight.

B. CO protein does not accumulate to sufficient levels in the phloem to promote the expression of the transmissible floral stimulus and the plant remains vegetative.

C. Under long days, the peak of CO mRNA abundance (at hours 12 through 16) overlaps with daylight (sensed by phyA and cryptochrome [cry]), allowing CO protein to accumulate.

D. CO activates FLC mRNA expression in the phloem, which causes flowering when the FT protein is translocated to the apical meristem.

Measurement of phytoplankton production, take sample of phytoplankton suspended in three bottles in lake. One bottle as control assumed as initial, second bottle (D) was kept in dark while third bottle (L) was kept in light. After some time productivity measure fallow

A- Difference in dissolved oxygen between light bottle and dark bottle yield NET primary productivity

B- Difference in dissolved oxygen between light bottle and initial bottle yield NET primary productivity

C- Difference in dissolved oxygen between light bottle and initial bottle yield Grass primary productivity

D- Difference in dissolved oxygen between light bottle and dark bottle yield total oxygen produced by photosynthesis

Which above combination of statement are correct?
