Answer:
b) a stickleback's aggressive behavior
Explanation:
Sticklebacks are small carnivores that live off of small animals and larvae. An adapted behaviour would be changes in their attitudes and behaviours as compared to the characteristics are given to them by the Creator.
For example lions nature is to hunt, spiders nature is to build nests whereas birds nature is to build nests. But being aggressive is not one of Sticklebacks natural instincts. This is something they have adapted with time due to external factors.
In liquids, particles are slightly spaced from each other and move around somewhat freely, but still bump into each other. Gases on the other hand move randomly and rarely bump into each other, thus they are more spaced out.
I think the answer is 1s²2s²2p⁶. Since neon has an atomic number of 10, we know that it needs to have 10 electrons and since it is in the second row it cannot have any d electrons which makes the first option incorrect. The second option is incorrect because the 2s⁴ can't exist since s orbitals can only hold 2 electrons. The fourth option cannot be right because it again neon cannot have d electrons due to it being in the second row.
I hope this helps. Let me know if anything is unclear.
