by the law of natural selection, daddy charles darwin stated that overpopulation could result in famine and wars, and death would accelerates across nations, so overpopulation is a cause for this because of too many organisms but not enough food, which declined growth rate.
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:
In chemistry and quantum mechanics, an orbital is a mathematical function that <u><em>describes the wave-like behavior of an electron, electron pair</em></u>, or (less commonly) nucleons. An orbital may also be called an atomic orbital or electron orbital.

Answer:
Complete questions include: Answer Bank: Guanine nucleotides, uridine nucleotides, adenine nucleotides, cytosine nucleotides.
Explanation:
Glycine Auxotroph: Guanine nucleotides and adenine nucleotides (Purine nucleotides)
Glutamine auxotroph: Guanine nucleotides and adenine nucleotides (purine nucleotides)
Aspartate auxotroph: Guanine nucleotides, uridine nucleotides, adenine nucleotides, cytosine nucleotides Both purine and pyrimidine nucleotides)
The amino acids glutamine, glycine, and aspartate provide all the nitrogen atoms of purines in a two ring-closure steps to form the purine nucleus. Pyrimidines are synthesized from carbamoyl phosphate and aspartate.
