Answer:
fixation
Explanation:
Nitrogen is converted from atmospheric nitrogen (N2) into usable forms, such as NO2-, in a process known as fixation. The majority of nitrogen is fixed by bacteria, most of which are symbiotic with plants. Recently fixed ammonia is then converted to biologically useful forms by specialized bacteria.
Sample answer
Layer D is the oldest because bottom layers form first and are covered by new rock layers.
Is an agency of the United States federal government whose mission is to protect human and environmental health.
Answer:
Morphology
Explanation:
Bacteria are usually identified by using standard molecular biology procedures, being the Polymerase Chain Reaction (PCR) the most widely used technique for this purpose. The identification by PCR consists of the amplification and visualization of specific DNA sequences that can be obtained from different individuals, strains, species, etc. However, it is also possible to identify bacteria with a microscope, i.e., by observing taxonomical characteristics that allow to differentiate specific bacteria.
Answer:
Explanation:
There is a total of 38 ATP produced. ATP is produced from 3 different steps. The first step is Glycolysis which produces 2 net ATP. Next, is the KREBS cycle (aka the Citric acid cycle) which also produces 2 ATP. The final step is the Electron Transport Chain, which produces 34 ATP.
Anabolic reactions require an input of energy, while catabolic reactions release energy. When talking about the metabolism, ATP is released through catabolic reactions. To grow and build muscles, for example, anabolic reactions are need (because you need food to gain muscle mass).
Anaerobic respiration means that NO OXYGEN is present while aerobic respiration takes place in the presence of oxygen. It is important to note that ONLY GLYCOLYSIS can occur during anaerobic respiration. Also, fermentation occurs during anaerobic respiration. There are two types of fermentation; lactic acid and "alcoholic". basically, lactic acid fermentation produces, well, lactic acid (which is used in yogurt and it's also the cramps you feel while running the mile in gym). Alcoholic fermentation is what is used to make alcohols like isopropanol or drinking alcohols like vodka.
Hope this helps :)
