C. They are specialized tissues that form an organ system.
hope it helps!
They are like that because they can't always be faulty and may have at least some spark of truth to this theory also as stated earlier a theory in scientific terms is just an observation so it can't really be turned down hence theory.
They cool too quickly to form crystal.
Cell division allows for the growing of new cells. With a unicellular organism, cell division would be the cell's way of reproducing or multiplying, in other words, surviving. Within a multicellular organism, cell division is the organism's way of replacing old, damaged, or dead cells. Within multicellular organisms, cell division also aids in growth.
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.
