Q5.27. Which of the following statements about the effects of climate change on phenology is true?
1. Climate-induced changes in phenology are expected, but have yet to be documented.
2. Temperature-cued spring events are occurring later, because winters are longer and cooler.

4. Changes in timing are more likely when events are cued by temperature, not day length.

a researcher conducts an experiment on the secretion of a particular hormone in mice. scientists inject mice with a substance that stimulates the production of the hormone. the scientists then test the levels of hormones produced by the mice. the tool used to measure the hormones consistently detects the levels at 10 points lower than the actual hormone levels in the mice. this tool makes measurements, but the measurements aren't .

after a the power stroke, adp is released, but the cross-bridge formed is still in place. atp then binds to myosin, moving the myosin to its high-energy state, releasing the myosin head from the actin active site.
