RNA. RNA is ribonucleic acid.
Answer:
The amount of oxygen in the atmosphere would decrease.
Explanation:
If a massive toxic spill kills off half the population of photosynthetic plankton in the ocean. That would mean that only half of the original population of plankton will remain. Photosynthetic plankton consumes carbon dioxide from the atmosphere during photosynthesis to produce energy and releases oxygen.
All answer choices are correct in soil conservation techniques prevents erosion.
<u>Explanation:</u>
- Decreasing tillage yields crops to settle in the soil preferably than being broken at the end of a season. The gain of no-till farming is consecutive to the soil structure, which transmits more deposits on the exterior to stand up against severe water and wind situations.
- With contour ploughing, preferably of seeding crops in straight lines, crops are planted based on the form lines of the area to form stores that save rainwater and lessen top-level soil erosion.
- Terracing is the habit of producing almost level areas in a hillside area. Terraces are shielded from erosion by other soil restrictions.
