Answer:
Oxygen for breathing in/out
A gamete has one copy of each chromosome, it is haploid.
A gamete is a haploid cell produced during the process of meiosis, it fuses with another haploid cell during fertilization in sexual reproduction. May be therefore described as mature haploid (single copy of chromosome) male or female germ cell that unites with another haploid cell and forms a zygote.
What is the rest of the question
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.
