Which number represents the cell responsible for color vision?

Please help a. How many chromosomes and/or sister chromatids do Figure A and B show? b. What is the name of the process that took place to get from structure A to structure B?

A classical experiment studying the fate determination of stem cells in the developing embryo uses the transplantation of somites from one organism to another. In such an experiment, a scientist transplanted somites 20, 21, and 22 from the right side of the neural tube from five-day-old developing quail embryos into chick embryos. The transplantation was performed in two orientations so that the order of the somites was sometimes reversed.   Use the passage to answer the question. Observations of the developing chick embryo reveal that skeletal muscles develop from the transplanted somites even though motor neurons innervating those muscles arise from chick neural crest cells. Based on these observations, what is MOST likely true?   A. Neural crest cells differentiate into somites.   B. Neural crest cells fuse with developing somite cells.   C. Neural crest cells develop from migrating somite cells.   D. Neural crest cells send projections into developing…
