Atoms gain electrons to form anions.
Atoms lose electrons to form cations.
Back in middle school, my chemistry teacher taught me a good way to remember whether an ion was a cation or an anion. When an atom loses an electron, it becomes positive, and when an atom gains an electron, it becomes negative.
Cation sort of sounds like “cat,” which is positive (Yay! Cats!).
Anions, on the other hand, sounds like “onion,” which is negative (Ew! Onions!).
There’s other ways of memorizing it, but this way was the easiest for me.

The correct answer is - C and D.
The principle of original horizontality means that the rock layers have been order by age, with the layers at the top being the youngest, while the layers at the bottom being the oldest.
In this picture it is little hard to tell which rocks belong to the same layer from first look because there are multiple twists and turns, an uneven surface, caused by pressure on the crust.
By carefully examining the image though, we can trace the layers more properly and see which ones are younger, which older, and which have the same relative age. In this case, we can see that the markings C and D are actually on the same layer of rocks, thus being a good indication that they have the same relative age.
<u>Answer:</u>
"Debt-for-nature swaps" are just "financial transactions" from which a part of a nation's (Developing nation) foreign debt is forgiven. This is done in exchange of "local investments" for the purpose of environmental conservation measures.
<u>Explanation:</u>
- The model for "debt-for-nature swaps", was outlined in the EAI (Enterprise for the Americas Initiative), was extended in the "Tropical Forest Conservation Act" (TFCA) to include the countries present around the world with 'tropical forests'.
- With the help of the program, "debt can be restructured" only in eligible countries, and 'funds' generated through this transactions are used to support programs for "conserving tropical forests" within the 'debtor country'.
- 124.8 million dollars has been spent under the 'TFCA' to restructure loan agreements in '13 countries' and nearly 218.4 million dollars in 'local currency' will be generated in the next 12-26 years for 'tropical forest conservation projects'.
- Thus, "debt for nature swaps" encourages the protection of "tropical rain forest".
