Which of the following is an accurate characteristic of bact

Which of the following is an accurate characteristic of bacterial cell walls? They are primarily made of chitin. They prevent cells from bursting in hypertonic environments. They prevent cells from bursting in hypotonic conditions. They only have peptidoglycan if they are gram-negative. Jams, jellies, preserves, honey, and other foodstuffs with high sugar content hardly ever become contaminated by bacteria, even when the food containers are left open at room temperature. This is because bacteria that encounter such an environment undergo death as a result of water loss from the cell. are unable to metabolize the glucose or fructose and thus starve to death. experience lysis. are obligate anaerobes. Are unable to swim through these thick and viscous materials. Prokaryotic ribosomes differ from those present in eukaryotic cytosol. Because of this, which of the following is Some antibiotics can block protein synthesis in bacteria without effects in the eukaryotic host. Eukaryotes did not evolve from prokaryotes. Translation can occur at the same time as transcription in eukaryotes but not in prokaryotes. Some antibiotics can block the synthesis of peptidoglycan in the walls of bacteria. Prokaryotes are unable to use a greater variety of molecules as food sources than can eukaryotes. If new genetic variation in the experimental populations arose solely by spontaneous mutations, then the most effective process for subsequently increasing the number of individuals that possess all of these beneficial mutations is transduction. binary fission. conjugation. transformation. meiosis. This bacterium derives nutrition by digesting human intestinal contents in other words, food). Humans lacking this bacterium have no measurable reproductive advantage or disadvantage relative to humans who harbor this bacterium. Consequently, the bacterium can be properly described as which of the following? symbiont endotoxin mutualist commensal 4 only 1 and 2

Solution

1)C)THEY PREVENT CELL FROM BURSTING IN HYPOTONIC CONDITIONS.

2)A)UNDERGO DEATH AS A RESULT OF WATER LOSS FROM THE CELL.

3)A)Some antibiotics can block protein synthesis in bacteria without effect in the eukaryotic host.

4)B)BINARY FISSION

5)A)4 ONLY
