An experimental diagram is shown in the diagram below: a. Green water plants release a gas in the presence of light.
b. Roots of water plants absorb minerals in the absence of light.
C. Green plants need light for cell division. d. Plants grow best in the absence of light.

During crossing-over, a. genetic material is exchanged between nonsister chromatids, resulting in new combinations of alleles. b. nonsister chromatids from each homologous chromosome of a tetrad are exchanged, resulting in new combinations of alleles. c. one homologous chromosome of a tetrad is exchanged with another tetrad, resulting in new combinations of alleles. d. sister chromatids from each homologous chromosome of a tetrad are exchanged, resulting in new combinations of alleles. e. genetic material is exchanged between sister chromatids, resulting in new combinations of alleles.
