It's okay to wipe surfaces with bleach solution without wearing gloves.

A. Mitochondria: Mitochondria are double-membrane organelles responsible for energy production in eukaryotic cells, but they are absent in prokaryotes.

B. Ribosomes: Ribosomes are present in both prokaryotes and eukaryotes, serving as the site of protein synthesis. Though their size differs (70S in prokaryotes and 80S in eukaryotes), their essential function is conserved across all cells.

C. Nucleus: The nucleus is a defining feature of eukaryotic cells, containing DNA within a membrane, but prokaryotes lack a true nucleus and instead have a nucleoid region.

D. Lysosomes: Lysosomes are membrane-bound organelles containing digestive enzymes, found in eukaryotes only and absent in prokaryotic cells.

E. All of the above: Not all listed organelles are found in both cell types, so this option is inaccurate since only ribosomes are shared universally.

A. Is found in the outer membrane of Gram-negative bacteria: Lipid A is a component of lipopolysaccharide (LPS) located in the outer membrane of Gram-negative bacteria, playing a key role in their structural integrity.

B. Is considered an endotoxin: Lipid A is the toxic portion of LPS and is classified as an endotoxin. It is released when Gram-negative bacteria die and the cell wall breaks apart.

C. Can cause fever, inflammation, and blood clotting in patients: When released into the host, Lipid A triggers strong immune responses that can lead to fever, shock, inflammation, and disseminated intravascular coagulation (DIC).

D. All of the above: Since Lipid A is a membrane component, functions as an endotoxin, and elicits severe immune reactions in patients, all the listed statements are accurate.
