<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>
Answer:
10
Explanation:
Proteins are polymers of amino acids. 20 different amino acids are present in various combinations in different proteins. Humans are incapable of synthesizing some amino acids. These are called the essential amino acids as they must be provided in the diet.
Histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine are the nine amino acids that are not synthesized in the body of adult humans and therefore, are categorized as essential ones. Arginine is a non-essential amino acid for adult humans but is essential for adult humans. Therefore, for an infant, more than 9 amino acids are essential ones.
