Answer:
99,614,720 cells
Explanation:
Since the population of E. coli doubles every 20 minutes, and one hour has three sets of 20 minutes, then six hours have 18 sets of 20 minutes or 18 generation lapses. In order to calculate the final rate of infection we need to calculate 18 doublings of the initial population of 380 cells, which equals to 99,614,720 cells.

Answer:True
Explanation: plants which lack vascular tissue is known as non-vascular plants. Vascular tissues consist of Phloem and Xylem.
Xylem vessels transport water and mineral through the plants while phloem vessels transport nutrients and products of photosynthesis via the plant.
Non vascular plants lacks features like Bark, so they do not grow very tall, they remain low on the ground. Examples include; mosses, liverworts etcetera.
Answer:
DNP produces the loss of the proton gradient (i.e., the energy of the proton gradient is dissipated in the form of heat instead to produce ATP)
Explanation:
2,4-Dinitrophenol (DNP) acts to shuttle H+ ions across cellular membranes, bypassing the ATP synthase used by mitochondria to generate ATP during cellular respiration. Since DNP is able to bypass ATP synthase, this compound uncouples the phosphorylation of ADP by the ATP synthase from the process of oxidation (i.e., transport of electrons). For example, in muscle cells, DNP may be used to shuttle calcium ions (Ca +) from mitochondrial stores, and free intracellular Ca+ ions are evidenced to produce muscle contraction.
