Amino acids
Remember that the structure of amino acids have an amino group (NH₃--Cα)
Explanation:
Plants will absorb the radioactive nitrogen compounds as ammonium (NH4+) nitrates (NO3-)and nitrites (NO2-). The radioactive Nitrogen will found in amino acids because the absorbed nitrates, nitrites and ammonium undergo a process called assimilation. The nitrates and nitrites are firstly reduced to ammonia. The ammonia is then assimilation is a pathway called glutamine synthetase-glutamate synthase (GS-GOGAT). IN this pathway the ammonia is incorporated into the amino group of glutamine using glutamine synthase enzyme. The process of transamination of the glutamine then creates many other amino acids.

Weathering and erosion played a big role in forming the grand canyon. The rock was being weathered, most likely mechanical weathering, and then it eroded away. Think of a pebble that is in running water. When you pick it up, it is smooth, right. But before, it was pointy. So, the grand canyon was once a big rock, and weathering broke through it making it one of the wonders of the USA.
They are similar to those of primary succession, primary succession occurs in an area without any initial. Succession always begins on a barren surface, whereas secondary succession be gains in environments that already possess soil. I hope this helps.
<h3><u>Answer;</u></h3>
- Catabolism is the process in which complex substances are broken down, yielding a net output of energy
- Metabolism is an integrated system in which many of the same reactions participate in degradative (catabolic) and biosynthetic (anabolic) pathways.
<h3><u>Explanation</u>;</h3>
- Metabolism is the chemical processes occurring within a living cell or organism that are necessary for the maintenance of life. In metabolism some substances are broken down to yield energy for vital processes while other substances, necessary for life, are synthesized.
- Catabolism is the metabolic breakdown of complex molecules into simpler ones, resulting in a release of energy. These reactions are exothermic.
- Anabolism involves the synthesis of polymeric biomolecules and complex lipids from monomers such as fatty acids and nucleotides. Anabolic reactions are endothermic.
