The product of the bicoid gene in drosophila provides essential information about
a) the dorsal-ventral axis
b) the left-right axis
c) segmentation
d) the anterior-posterior axis

The correct answer is: D) the anterior-posterior axis

Bicoid gene encodes for the protein that is very important for embryogenesis of Drosophila. Bicoid protein concentration gradient patterns the anterior-posterior (A-P) axis or simply saying determines which end is the front end of the embryo.

Bicoid gene is maternal-effect gene meaning that zygote inherits the Bicoid directly from its mother.

above statement is not a true statement about the open ocean because the open ocean has low levels of nutrients. most of the photosynthetic activity on earth occurs in the open ocean within the photic zone. organisms in the deep ocean are exposed to frigid temperatures and total darkness but it does not begin at the low-tide mark.

what? are the statements?
