Prior to the invention of refrigeration, meat was often preserved by soaking it in brine (a solution of water with a high concen
tration of salt) to kill any microorganisms that might have tried to use the meat as their own food source. Which of the following BEST explains how a brine solution could be lethal to those microorganisms? Water would move into the cells of the microorganisms by osmosis causing it to swell and burst. The salt would move into the cells of the microorganisms by facilitated diffusion causing the membrane to become rigid and less permeable. The salt would be pulled from the cells of the microorganisms by active transport removing necessary nutrients and destroying the cells. Water would move out of the cells of the microorganisms by osmosis and the cytoplasm would become dehydrated, killing the cells.
Water would move out of the cells of the microorganisms by osmosis and the cytoplasm would become dehydrated, killing the cells. The brine is a hypertonic solution, thereby "pulling" the water out of the bacterial cells.
If people would clean up after themselves, the world's rivers and lakes would be clean. Water pollutants can be somewhat easy to remove by taking the trash out of them.
The cells at the end of meiosis II must have half the number of chromosomes because, if they didn't have, the reunion of both gametes with diploid number of chromosomes for example, in gametes would form twice the number chromosomes.
