Problem:

Question 1: Which axis develops first in plants, anterior-posterior or dorsal-ventral?

a. A-P
b. D-V
c. They develop at the same time.
d. Plants only develop A-P, and with respect to gravity and light.

Question 2: Focusing in on A-P development in Drosophila, maternal transcription factors produce proteins that control axis development in what order?

a. bicoid and nanos proteins; caudal and hunchback proteins; gap and pair-rule proteins
b. caudal and hunchback proteins; bicoid and nanos proteins; gap and pair-rule proteins
c. gap and pair-rule proteins; bicoid and nanos proteins; caudal and hunchbackm proteins
d. gap and pair-rule proteins; caudal and hunchback proteins; bicoid and nanos proteins

Question 3: What ultimately controls pattern formation in Drosophila?

a. Morphogen gradients and signaling molecules under maternal control
b. Morphogen gradients and signaling molecules under embryonic control
c. De-repressors and signaling molecules under maternal control
d. De-repressors and signaling molecules under embryonic control
