When usingthe standard proteins it is typically assumed that the vv values of thestandard and actually measured protein are identical. With thisassumption, the ratio of the molecular masses of the two proteins isidentical to the ratio of their I(0)s normalized against the concen-trations.
The gametes (an egg and a sperm) fuse in the process of syngamy to form a 2 n zygote. The zygote divides mitotically to form a multicellular embryo ( embryogenesis), which is protected by either gametophytic tissues (such as remnants of archegonia in the nonseed land plants) or sporophytic tissues (the seed in the seed plants). An embryo,...
The Germ Layers. The Germ Layers are a group of cells, formed during embryogenesis and eventually give rise to all of our tissues and organs through the process of organogenesis. From inner to outer, the germ cell layers are the endoderm, mesoderm, and ectoderm. The division of the germ layers is especially evident during embryogenesis, when the embryo grows from a single fertilized egg into an organism ready to live on its own. Together the germ layers make up the organism.
