Answer:
Explanation:
In the process of differentiation the stem cells develop different sub-cellular structures to turn into the different types of cells - specialisation. The specialised cells can now carry out their important specific functions - essential for the efficient and healthy viability of any organism.
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.
It's harder to find one of the many genes involved in a polygenic trait vs the only gene involved in a discrete trait.
