Answer:
A. The number of electrons of a neutral atom always equals the number of protons.
Explanation:
Because the atom is neutral, meaning it has no charge, the protons and electrons would therefore have to be the same. Electrons carry a negative charge while protons carry a positive charge. If you had one more electron than proton, you would have a charge of -1. If they are equal, it would have no charge and be named neutral.
DNA is considered the building blocks of life.
<span>Nitrogen and phosphorous are the most prevalent aquatic pollution and contribute heavily to the excessive growth of algae in aquatic environments called algae blooms. The nitrogen from the fertilizers is found in molecules called nitrates which are compounds of both oxygen and nitrogen. Phosphorous helps algae to absorb carbon dioxide. So when the phosphorous levels are high the algae absorbs more carbon dioxide, which allows for faster photosynthesis and faster glucose production which leads to faster growth. Although algae need both nitrogen and phosphorous to grow, when the levels are too high the algae grows faster than the ecosystem can sustain leading to oxygen deprivation for the other aquatic organisms.</span>
