Answer:
The pathway likely taken is ER - Golgi - vesicles that merge with the plasma membrane.
Explanation:
The endomembrane system comprises a complex network of internal membranes. It was first identified in the late 19th century when Camillo Golgi observed that a specific stain selectively colored certain cellular membranes. Golgi believed these membranes were interconnected; however, subsequent developments in microscopy and biochemical analysis revealed that the organelles within the endomembrane system function as distinct compartments with specialized roles.
The AraC protein associated with the ara operator functions as a repressor to prevent transcription of the ara operon. In the presence of arabinose, the AraC protein acts as an activator; however, in its absence, it serves as a repressor. When arabinose is not available, AraC remains as a
homodimer. One AraC molecule attaches to the ara initiator while another binds to a distinct regulatory region in the DNA known as the ara operator.
The solute potential is indicated by the formula P = -iCRT, with i representing the ionization constant, C being the molar concentration, R as the pressure constant (R = 0.0831 liter * bars/mole * K), and T signifying the temperature in Kelvin (273 + °C). A 0.15 M NaCl solution at standard atmospheric pressure and 25°C has an osmotic potential of -7.4 bars, with Na+ and Cl- yielding 2 ions (in contrast to sucrose, which counts as one). Therefore, i = 2, and osmosis will drive water from the 0.1 to the 0.15 concentration.
Answer:
cell membrane, DNA and RNA, cytoplasm, along with ribosomes
Explanation:
Prior to touching the chicken, lettuce, tomato, and bun, the food handler needs to wash their hands. Additionally, they must ensure they are donning the appropriate gear, which could include a mask, gloves, and goggles if necessary, to avoid any potential food contamination.
