The stage that occurs between the 4-cell stage and the 16-cell stage in embryonic development is the morula stage. The morula is a solid ball of cells formed by multiple divisions of the fertilized egg.
During the fourth week implantation of fetal development takes place. At this stage the fertilized egg is now called a blastocyst.
Glycolysis occurs in the cytoplasm during the first stage of respiration.
Glycolysis, the first stage of respiration, occurs in the cytoplasm.A molecule of glucose splits into two molecules of pyruvate. No oxygen is needed for this stage of respiration and it occurs in cells that respire using mitochondria and cells that ferment sugars.
Prophase occurs during the first stage of the cell cycle, which is the mitotic phase. It is characterized by the condensation of chromatin into visible chromosomes, the disintegration of the nuclear envelope, and the formation of the mitotic spindle.

The fetal period of development occurs during the third stage of prenatal development, which is the fetal stage.

Development of the germinal cell layers occurs very early in fetal development.
The development stage you are referring to is likely the accumulation of adipose tissue (fat) beneath the skin. This typically occurs during the growth and maturation stages of development.
A fetus develops a nervous system during the embryonic stage of development, which occurs around the 3rd to 8th week of pregnancy.
Implantation occurs during the blastocyst stage of prenatal development, typically around 6-10 days after fertilization. During this stage, the blastocyst embeds itself into the lining of the uterus in a process that is essential for pregnancy to continue.
The stage of cognitive development when children learn to coordinate vision with touch is the sensorimotor stage, according to Jean Piaget's theory of cognitive development. In this stage, which typically occurs from birth to age 2, infants develop object permanence and understand that objects still exist even when they are out of sight.
