embryo
Twin development can occur at the cleavage stage if the developing embryo splits into two separate parts early in development. This can happen due to genetic factors or environmental influences. As the cells continue to divide and differentiate, each part of the embryo can develop into a separate individual, giving rise to monozygotic twins.
The two processes included in prenatal development of a human embryo are cleavage, where the initial cell divides into multiple cells, and gastrulation, when the cells organize into the three germ layers of the embryo: ectoderm, mesoderm, and endoderm.
puberty and gastrulation!!
i honestly dont know was looking for the same answer :(
Lack of interest and vision problems are two factors affecting effective reading. A weak vocabulary or knowledge base also affects reading.
An embryo can split into two separate embryos during the early stages of development, typically within the first two weeks after fertilization. This process is known as twinning. In rare cases, splitting can occur later in development, up to around 13 days after fertilization.
embryo The first three months of pregnancy are the first trimester
Fetus (Pronounced 'Feetus')I did the names in bold:Oocyte -> fertilization -> Fertilized Ovum-> cleavage (cell division) -> Morula -> Blastocyst -> attachment to Uterine wall -> Implantation -> Embryoblast -> Embryo -> After the first two months of development, the embryo is called a Fetus until birth

The type of cell division that occurs in the early embryo is called mitosis. Mitosis is a process where a single cell divides into two identical daughter cells, allowing for growth and development of the embryo.
