Answer:
The correct answer is D. A gram-negative cell wall consists of a thin layer of peptidoglycan surrounded by an outer membrane containing lipopolysaccharides.
Explanation:
Gram-negative bacteria are bacteria that do not retain the gentian violet dye during the Gram staining protocol.
During the Gram staining process, a contrast dye, usually safranin, is added after gentian violet, causing the Gram negative bacteria to stain pink or red. The contrast dye thus allows the visualization of Gram-negative bacteria which, because they have a thinner layer of peptidoglycans, cannot retain the gentian violet dye.
Its main feature is an endotoxin called lipopolysaccharide that causes pathogenicity and is responsible for its virulence.
Answer:
They are carbohydrates containing a terminal aldehyde or ketone group which can undergo oxidation reactions. By reacting with free amino groups in amino acids, peptides and proteins, reducing sugars can form unique compounds essential for the desirable flavor and aroma of baked goods.

Phospholipids which are the main component of the cell membrane and is what helps the cell membrane to conserve internal fluids
You should use the same amount of beads for both chromosomes because they need to match in size.
I am assuming you are making a pair of homologous chromosomes out of pop beads, and they should have the same size because they code the same information, the only difference between them is that one comes from the mother and ther other from the father. (Homologous chromossomes have the same genes in the same loci).
