Answer:
In gram-negative bacteria, the thin layer of peptidoglycan is surrounded by an outer membrane made of phospholipids, lipopolysaccharides, and proteins. This statement accurately describes specific bacterial cell walls.
Explanation:
The Gram- negative bacteria constitute of an outer membrane which is richly made up of lipopolysaccharides, phopholipids and proteins. The lipopolysaccharides function mainly as a virulence factor and are involved in causing variety of diseases in animals.
Gram- negative bacteria can be seperated from gram- positive bacteria mainly because of the thickness of peptidoglycan and by the presence of the outer membrane of Gram- negative bacteria. The outer membrane is absent in Gram- positive bacteria.
Answer:
Natural selection. It is simply the process by which random variations that give an individual a favorable adaptation to its environment survive to be passed on to offspring.
Answer:
Option C
Explanation:
In G2 phase (third phase of interphase) of cell division, following the S phase. It is during the S phase of the cell division during which the DNA of the cell replicates. Hence, in the G2 has double the DNA range as compared to the DNA range in prior stages of interphase. Also, in G2 phase cell grows and protein synthesize
Option C is correct
