Answer:(Mendel's Second Law of Inheritance) Independent Assortment
Explanation:
Mendel is one of the fathers of genetics science and here are four law and postulates in the sphere of inheritance he shared: • Principle of Dominance • Principles of Paired Factors
• (Mendel's First Law of Inheritance) Law of Segregation or Law of Purity of Gametes and • (Mendel's Second Law of Inheritance) Law of Independent Assortment
Answer:
Nitrate
Explanation:
Bacteria can direct their movements according to the presence of particular molecules found in the environment. Chemotaxis enables the movement of bacteria in response to environmental factors, including chemical factors. Nitrate is an anion (i.e., negatively charged) that acts both as an electron acceptor during anaerobic respiration as well as a source of nitrogen during aerobic growth. Bacterial nitrate chemotaxis is a phenomenon that occurs under environmental conditions associated with nitrate starvation (i.e., nutrient stress), during the life cycle of diverse types of bacteria. Moreover, methyl-accepting chemotaxis proteins are receptors widely distributed in the cytoplasmic membrane of bacteria and archaea. These receptors form hexagonal arrays that act in signal transduction pathways by processing environmental inputs (in this case, nitrate conditions).
