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.
3. Changes in phenology do not affect reproduction and therefore have no impact on fitness.
4. Changes in timing are more likely when events are cued by temperature, not day length.

idk what the options are but

these is a strong electrostatic attraction between the ions hence a lot of energy is needed to overcome this attraction

this is why the boiling points are so high

blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium of the heart. as the ventricle contracts, blood leaves the heart through the pulmonic valve, into the pulmonary artery and to the lungs where it is oxygenated.
