proteins, like ion channels, in cellular membranes

All of the following statements about plant embryogenesis are correct EXCEPT
Late stages of embryogenesis involve dessication of embryonic tissues
The suspensor is derived from the basal cell

Mouse sperm contain receptor proteins that bind to a glycoprotein (ZP3) in the zona
pellucida of mouse eggs. Binding of ZP3 receptors to ZP3 initiates the sperm's
acrosomal reaction. All of the following experimental observations would be
expected EXCEPT
Injecting eggs with antibodies that bind to ZP3 blocks in vitro fertilization
Coating synthetic beads with ZP3 leads to sperm aggregation on the beads
,Incubating sperm with purified ZP3 prior to mixing sperm and eggs blocks in vitro
fertilization.
Coating synthetic beads with a different glycoprotein, ZP2, fails to lead to sperm
aggregation on the beads-
Incubating eggs with antibodies that bind to ZP3 blocks in vitro fertilization

In garden peas, the allele for tall plants (D) is completely dominant to the allele for
dwarf plants (d) and the allele for violet flower color (W) is completely dominant to
the allele for white flower color (w). In a cross between a tall violet plant, with the
genotype DDWw, and a dwarf white plant, what phenotypic ratio of the progeny
would be expected from this cross?
Answers:
All tall violet
1 tall violet: 1 tall white: 1 dwarf violet: 1 dwarf white
1 tall violet: 1 tall white
1 tall violet: 1 dwarf violet
All dwarf white

1 tall violet: 1 tall white
