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.
The right answer is It does not show that photosynthesis consists of many separate reactions.
It takes six molecules of carbon dioxide and six molecules of water to synthesize a molecule of glucose, releasing six molecules of oxygen, thanks to the light energy.
6 CO2 + 6 H2O + light energy ==> C6H12O6 (glucose) + 6 O2
<u>But this balance is in fact broken down into two successive stages:</u>
Light phase or photochemical phase:
12 H2O + light ==> 6 O2 + chemical energy (24 H).
The Calvin cycle (dark phase):
6 CO2 + chemical energy (24 H) ==> C6H12O6 + 6 H2O.
The role of the top predator is to maintain the balance between the population of secondary consumers, primary consumers and the producers. The removal of the sea otters, a top predator will lead to the increase in the number of the secondary consumers that include the creatures like the crabs, frogs, fishes, etc. These creatures are also eaten by the gulls and the eagles. This will lead to increase in the number of the gulls and the eagles as they have more food for themselves. The removal of sea otter decreases the competition over food with the gulls and the eagles. This is an indirect benefit to them.
The most abundant element in the human body is oxygen
