Context and question: Plant circadian rhythms tell the plant what season it is and when to flower for the best chance of attracting pollinators. Behaviors showing rhythms include leaf movement, growth, germination, stomatal/gas exchange, enzyme activity, photosynthetic activity, and fragrance emission, among others. Circadian rhythms occur as a plant entrains to synchronize with the light cycle of its surrounding environment. These rhythms are endogenously generated and self-sustaining and are relatively constant over a range of ambient temperatures. Important features include two interacting transcription-translation feedback loops: proteins containing PAS domains, which facilitate protein-protein interactions; and several photoreceptors that fine-tune the clock to different light conditions. Anticipation of changes in the environment allows appropriate changes in a plant's physiological state, conferring an adaptive advantage. A better understanding of plant circadian rhythms has applications in agriculture, such as helping farmers stagger crop harvests to extend crop availability and securing against massive losses due to weather.
What plant behavior is not controlled by circadian rythems??
Answer: unanswerable
Context and question: Passos Coelho also announced that the retirement age will be increased from 65 to 66, announced cuts in the pensions, unemployment benefits, health, education and science expenses, abolished the English obligatory classes in Basic Education, but kept the pensions of the judges, diplomats untouched and didn't raise the retirement age of the military and police forces. He has, however, cut meaningfully the politicians salaries. These policies have led to social unrest and to confrontations between several institutions, namely between the Government and the Constitutional Court. Several individualities belonging to the parties that support the government have also raised their voices against the policies that have been taken in order to try to solve the financial crisis.
To what age did Passos Coelho increase the retirement age?
Answer: 66
Context and question: Since all contact between the wrestlers must cease if any part of the body is touching, or underneath, the ropes, many wrestlers will attempt to break submission holds by deliberately grabbing the bottom ropes. This is called a "rope break", and it is one of the most common ways to break a submission hold. Most holds leave an arm or leg free, so that the person can tap out if they want. Instead, they use these free limbs to either grab one of the ring ropes (the bottom one is the most common, as it is nearest the wrestlers, though other ropes sometimes are used for standing holds such as Chris Masters' Master Lock) or drape their foot across, or underneath one. Once this has been accomplished, and the accomplishment is witnessed by the referee, the referee will demand that the offending wrestler break the hold, and start counting to five if the wrestler does not. If the referee reaches the count of five, and the wrestler still does not break the hold, they are disqualified.
When must contact stop between wrestlers?
Answer:
if any part of the body is touching, or underneath, the ropes,
