The answer is "Decomposers directly convert ammonium into nitrogen gas".
Living organisms such as plants and animals contains nitrogen in the form of the amino acids and proteins. When they die, the nitrogen in the form of ammonium is decomposed by microorganisms. It is then converted into nitrites and then to nitrates by nitrifying bacteria. The denitrifying bacteria then converts nitrates into nitrogen.
The answer is A smaller fragments will move faster.
The chloroplast is the part I believe.
Answer:
The correct options are:
c. phenylalanine
f. tyrosine
Explanation:
The specificity of the pocket of chymotrypsin is for <em>aromatic aminoacids</em> o amino acids with <em>bulky hydrophobic chains</em>. From the list of amino acids, the aromatic amino acids are <em>phenylalanine</em> (with a phenyl group) and <em>tyrosine </em>(with a phenolic group).
From the rest, there are not amino acids with bulky hydrophobic side chains. Arginine has a 3-carbon side chain but it has a polar guanidino group, so it is not a bulky hydrophobic R-group. Alanine is hydrophobic but it is not bulky - it has only a methyl (-CH₃) group as R-group. Aspartate is not hydrophobic neither aromatic. Finally, glycine is very simple, it has only a -H as R-group.
Answer:
The statement that best describes the vascular tissue in seed plants is that xylem carries water and nutrients from the roots to the rest of the plant.
Explanation:
Xylem corresponds to the tissue of the vascular plants that is responsible for the transport and distribution of liquids necessary for their development.
The main function of xylem is to<u> carry water, mineral salts and other nutrients -in the form of raw sap- from the root to the whole plant</u>, forming a network similar to the circulatory system of higher animals.
