Answer:
A. Gram positive bacteria
Explanation:
Gram-positive bacteria have the cell wall that consists of a single thick layer of peptidoglycan. This peptidoglycan layer is 20-80 nm thick in Gram-positive bacteria. On the other hand, the peptidoglycan layer in cell walls of Gram-negative bacteria is only 2-7 nm thick.
The thicker peptidoglycan layer of Gram-positive bacterial cells makes them more resistant to osmotic stress than the Gram-negative cells.
If you mean where lipids come from, we get them from food like butter, oils, avocados, etc.
If you're asking how we absorb lipids, lipids get broken down into fatty acids and glycerol which are absorbed by the lymphatic system through lacteals in the villi of the small intestine.
