Answer:
Interrupt the long winter nights with a brief period of light.
Explanation:
Long day plants, also called short night plants, flower when the dark period is equal or less than the critical period specific for the species. These plants normally flower in summers when nights are short and days are longer. Winters have a long dark period and do not support flowering in shirt night plants.
A continuous dark period is critical for flowering. A short night plant can flower in winters (having longer dark periods) if the dark period is interrupted by exposing the plant with a flash of light. To make short night plants, such as iris to flower in winters, the plant should be given short period of light after completion of critical dark period.

Answer:water
Explanation:
Carbon dioxide as a non-metallic oxide is acidic. Carbon dioxide reacts with water in a reversible reaction to form carbonic acid (H2CO3).
Answer:
if the promoterless lacZ is inserted close to any gene(s) or operon, then the laz gene will also be transcribed when the operon gets expressed. The polycystronic RNA will eventually produce a beta-galactosidase protein(product of lacZ gene) which will cleave X-Gal( structural analog to lactose), which will produce blue chromogenic substance.
prepare LB agar. Allow it to cool, add X-gal before it solidifies, pour to plates.
create grids and patch plate each strain on it. Just pick the strain that looks blue, amplify the sequence upstream of the lacZ and sequence it.
