A fish swimming into an estuary from a river would have which of the following as its greatest physiological challenge?

#SCPH06 I Botany
  1. The high water flow would make the fish expend more energy.
  2. The low oxygen content would give the fish difficulty in swimming aerobically.
  3. The temperature change would stress the fish by denaturing its proteins.
  4. The change in water solute content would challenge the osmotic balance of the fish.

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.
