Answer:
C. oxidative deamination requiring NAD⁺.
Explanation:
Oxidative deamination is the first step in breaking down the amino acids in order to be converted into sugars. This process begins by removal of amino group of the amino acids. The amino group then becomes ammonium as it is lost and subsequently, undergoes the urea cycle to become urea in the liver. From there, It is released into the blood stream, where it is transferred to the kidneys, which will secrete the urea as urine.
The remaining portion of the amino acid becomes oxidized, forming an alpha-keto acid. The alpha-keto acid thus proceed into the Citric acid cycle, in order to produce energy.
The alpha-keto acid can also enter glycolysis, where it will be eventually converted into pyruvate. The pyruvate is then converted into acetyl-CoA so that it can enter the Citric acid cycle cycle and convert the original pyruvate molecules into ATP, or usable energy for the organism.
Prophase is the first phase of mitosis, this when the nuclear envelope breaks down and the nucleuse disappears. Hope I was able to help. :)
The answer is xylem
Explanation
Xylem transports and stores water and water-soluble nutrients in vascular plants. Phloem is responsible for transporting sugars, proteins, and other organic molecules in plants. Vascular plants are able to grow higher than other plants due to the rigidity of xylem cells, which support the plant.
This is an example of a placebo effect. A placebo is something that seems to be a "real" medical treatment but the truth, it isn't. It could be a pill, an injection, or some other kind of "fake" treatment. What all placebos have in common is that they do not encompass an active substance meant to affect health.
Answer:
Bacteria
Explanation:
Bacteria are a group of single celled organisms that are neither plants or animals.
Bacteria lack cell organelles such as the nucleus and the chlorophyll.
They can be found in many environments and most of them are adapted to survive in extreme environments such as hot-springs where the temperatures are extremely high.
Unlike the plant cell wall, bacterial cell wall has a layer of peptidoglucan which determines their shape. Their cytoplasm contains both DNA and RNA.
