When compared with other varieties of honey in scientific studies, Manuka honey has the highest and broadest antibacterial activity. Manuka honey is used to treat many types of wound, including: traumatic wounds, surgical incision sites, burns, sloughy wounds, and pressure ulcers. When talking about manuka honey used in skin infections, we are actually talking about medical grade honey.
The embryo is present at five to six days after the zygote is fertilized. The embryo is a clump of cells inside the formerly hollow blastocyst, and is surrounded by the trophoblast. The trophoblast contains cells that direct hormone production and implantation. After the embryo forms, the cells form the embryonic disk.
So the first thing that visibly happens to a zygote is that it divides by mitosis into two cells, then they divide to form a four-celled embryo, and so on.Eventually the ball of identical-looking cells hollows and acquires an axis, and differentiation begins. For more detail, see the links below. zygote is a fertilized egg, i.e. an egg cell and a sperm stuck together. An embryo is a fetus before it actually looks like a baby.
