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,...
Development of the nervous system. The embryo consists of three layers that undergo many changes to form organ, bone, muscle, skin, or neural tissue. Skin and neural tissue arise from one layer called the ectoderm. This occurs in response to the adjacent layer, the mesoderm.he cells of the nervous system are of a specific type and form over the course of an organismâs life.
