Both. You can use it as singular or plural.
Answer:
Controlling the proteins in an organism controls the organism's characteristics because proteins are enzymes, and enzymes catalyze and regulate chemical reactions, and therefore can control certain traits such as color, shape, or even gender.
Explanation:
Answer:
Tissues exist within organs, which exist within organ systems. Communities exist within populations, which exist within ecosystems. Organelles exist within cells, which exist within tissues. Communities exist within ecosystems, which exist in the biosphere.
Explanation:
The name of the great storm is Hurricane Katrina.
Answer:
Aerobic respiration is the process or set of cycles that producing cellular energy with the help of oxygen. In this process cells, breakdown glucose in the multi-step process in which the very first step is glycolysis, the second is the Krebs's cycle and the third is the electron transport system in the mitochondria.
<u>Glycolysis</u>: It is the first step of cellular respiration that is enzyme based metabolic reaction that converts glucose into pyruvate and releases energy in the form of ATP and NADH. The net gain of the pathway is two ATP and two NADH.
Pyruvate oxidative link is an intermediate reaction between glycolysis and Krebs cycle that converts pyruvate to acetyl CoA.
<u>Krebs cycle:</u> It is a pathway involves chemical reactions release stored energy through the oxidation of acetyl CoA derived from pyruvate into adenosine triphosphate and carbon dioxide.
<u>Electron transport system:</u> all previous steps reduce the electron carriers to NADH + H+ and FADH2. Then these donate protons and electrons to the electron carrier proteins of the ETS system. In the end, the electron accepted by oxygen.
