Answer
Plants can respond to the change of season by losing their leaves, flowering, or breaking dormancy. Plants go through seasonal changes after detecting differences in day length.

Answer:
b)
Explanation:
hydrogen bond is a form of dipole-dipole interaction but with more unique properties
Answer:
metal atoms lose electrons to form positive ions (cations)
Explanation:
metal atoms lose electrons to form positive ions (cations ) non-metal atoms gain electrons to form negative ions (anions )
Answer: C)Anion, it would gain 2 electrons to satisfy the octet rule.
Explanation:
Electronic configuration represents the total number of electrons that a neutral element contains. We add all the superscripts to know the number of electrons in an atom.
The electrons are filled according to Afbau's rule in order of increasing energies and thus the electronic configuration of oxygen with 8 electrons is
![O:8:1s^22s^22p^4](https://tex.z-dn.net/?f=O%3A8%3A1s%5E22s%5E22p%5E4)
The cation is formed by loss of electrons and anions are formed by gain of electrons.
In order to complete its octet and get stable, it gains 2 electrons and thus would form an anion.
![O^{2-}:10:1s^22s^22p^6](https://tex.z-dn.net/?f=O%5E%7B2-%7D%3A10%3A1s%5E22s%5E22p%5E6)
