A four-cell embryo normally develops into a blastocyst consisting of trophectoderm (TE) cells on the outside and inner cell mass (ICM) cells inside. The transplantation experiments were done with mouse embryos.

A. If a labeled cell is placed on the outside of a very early embryo, it is likely to form extraembryonic tissues.

B. If a labeled cell is placed on the inside of a very early embryo, it is likely to form embryonic tissues.

According to above observations which of the following statement is true?

#Unit 5. Developmental Biology
  1. The fate of a cell in the early embryo—TE or ICM—is determined by the cell’s position and shows regulative development.
  2. The fate of a cell in the early embryo—TE or ICM—is determined by the cell’s position and shows mosaic development.
  3. The fate of a cell in the early embryo—TE or ICM—is determined in the position independent manner and shows mosaic development.
  4. The fate of a cell in the early embryo—TE or ICM—is determined in the position independent manner and shows regulative development.

In some cells, there are many ion electrochemical gradients across the plasma membrane even though there are usually only one or two proton pumps present in the membrane. The gradients of the other ions are most likely accounted for by:
