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,...
During this stage, all of your baby's major organs and body parts begin to develop. The cells of the embryo (called embryonic stem cells) multiply and change into the hundreds of different types of cells needed to make a whole human body.The placenta also develops during the embryonic stage. This is one of the first things to develop during the embryonic stage. 2  This means your babyâs brain, spinal cord and nerves form during this stage. 3  Heart. 4  An S-shaped tube forms on the front of the embryo.
