Which of the following is the correct sequence for the germination of the eudicot seed? a) the two cotyledons have absorbed the endosperm and supply the nutrients to the embryo. as the embryo emerges from the soil it consumes the nutrients and develops the shoot. the hypocotyl becomes part of the stem and the radicle develops into the roots. b) the cotyledon was absorbed by the endosperm and supplies the nutrients to the embryo. as the embryo emerges from the soil it consumes the nutrients and develops the shoot. the hypocotyl becomes part of the stem and the radicle develops into the roots. c) the two cotyledons have absorbed the endosperm and supply the nutrients to the embryo. as the embryo emerges from the soil it consumes the nutrients and develops the shoot. the radicle becomes part of the stem and the hypocotyl develops into the roots. d) the pericarp has absorbed the endosperm and supply the nutrients to the embryo. as the embryo emerges from the soil it consumes the nutrients and develops the shoot. the hypocotyl becomes part of the stem and the radicle develops into the roots. e) the two cotyledons have absorbed the endosperm and supply the nutrients to the embryo. as the embryo emerges from the soil it consumes the nutrients and develops the shoot. the plumule and the radicle push through the coleorhiza during germination.

The gene that causes sickle-cell disease is present in a higher percentage of residents of sub-saharan africa than among those of african descent living in the united states. even though this gene causes sickle-cell disease, it also provides some protection from malaria, a serious disease that is widespread in sub-saharan africa but absent in the united states. discuss an evolutionary process that could account for the different percentages of the sickle-cell gene among residents of the two regions.

In a hypothetical breed of dogs, coat color is controlled by two genes. there are six different coat colors in this breed: black, brown, cream, gray, silver, and tan. consider the following crosses.cross 1: black females from a lineage of all black dogs are crossed with brown males from a lineage of all brown dogs. f1 males and females are all black. when f1 are intercrossed, f2 males and females are black or brown.cross 2: black females from a lineage of all black dogs are crossed with tan males from a lineage where all males are tan and all females are cream. f1 males are black, f1 females are gray. when f1 are intercrossed, f2 males and females are black, brown, gray, or tan.cross 3: silver females from a lineage where all females are silver and all males are gray are crossed with brown males from a lineage of all brown dogs. f1 males and females are all gray. when f1 are intercrossed, f2 males are black, brown, gray, or tan, f2 females are cream, gray, silver, or tan.select the correct statements regarding the mode of inheritance of the coat color genes.a) both genes are x-linked.b) both genes are autosomal.c) one of the genes modifies the expression of the other gene.d) each gene has an additive effect on the intensity of coat color.e) each gene independently specifies three colors.f) one of the genes is autosomal, and the other is x-linked.
