Answer:
The exceptions to the periodic trends in ionization energy are the first ionization energy of beryllium is higher than that of boron and the first ionization energy of nitrogen is also higher than that of oxygen.
Explanation:
Taking a close look at the figure of first ionization energies, it clearly shows that the first ionization energy of beryllium is higher than that of boron and the first ionization energy of nitrogen is also higher than that of oxygen.
This is as a result of Hund's rule and electron configuration. For example, the first ionization potential electron of beryllium is obtained from a 2s orbital while that of boron comes from a 2p electron. However, for oxygen and nitrogen, their electrons are obtained from 2p orbitals. While spin is uniform for all 2p electrons of nitrogen, it is different for oxygen.

Answer:
A.) Absorb and store
Explanation:
The reaction for photosynthesis is:
→ 
(reaction conditions: light and chlorophyll)
<em>carbon dioxide + water → glucose + water</em>
<em />
This means light energy is <u>absorbed</u> and <u>stored</u> as sugar molecules and energy for the plant
Therefore, the photosynthesis reaction will <u> absorb </u> energy and <u> store </u> it in the chemical bonds.
"The boron-nitrogen interaction in the studied molecules shows some similarities with the N→B bond in the H3N-BH3 molecule, formally understood as covalent-dative. ... The results show that all the studied BN bonds are triple, since three two-center orbitals have been obtained."
"Formation of a dative bond or coordinate bond between ammonia and boron trifluoride. When the nitrogen donates a pair of electrons to share with the boron, the boron gains an octet. ... In addition, a pair of non-bonding electrons becomes bonding; they are delocalized over two atoms and become lower in energy."
