Answer:
2Na + MgF2(make the 2 the ones that are small at the bottom cause I can't type it out-) turns into 2NaF + Mg
Explanation:
Now it is balanced because on both sides we have 2Na's, 1Mg and 2F's
The answer should be C, the heart and the blood vessels.
The heart acts as a pump in the circulatory system. It pumps blood to organs and tissues all around the body. Meanwhile, the blood vessels (arteries, veins, and capillaries) help transport the blood to tissue and cells and back to the heart. Each type of blood vessel has their own function.
The brain is not involved in this system, as the whole circulation process does not require any us to make any decision.
In addition, there's also one structure that is in the blood vessels, but technically not another item for the circulatory system. That's valves, they are like flaps that ensure blood flowing in one wag direction and to prevent the back flow of blood.
So, the answer is C.

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.
