question 98

Multiple Choice

Embryonic induction,the influence of one group of cells on another group of cells,plays a critical role in embryonic development.In 1924,Hans Spemann and Hilde Mangold transplanted a piece of tissue that influences the formation of the notochord and neural tube,from the dorsal lip of an amphibian embryo to the ventral side of another amphibian embryo.If embryonic induction occurred,which of the following observations justifies the claim of embryonic induction?

• A)The transplanted tissue induced multiple limbs to develop on the ventral side of the recipient embryo.
• B)The transplanted tissue inhibited normal cell division on the dorsal side of the recipient embryo that lead to its death.
• C)The transplanted tissue had no effect on either the ventral or dorsal side of the recipient embryo so it continued to develop normally.
• D)The transplanted tissue induced the formation of a second notochord and neural tube on the ventral side of the developing embryo.
• E)The transplanted tissue caused a second embryo to form.
