B) membrane potential
C) gravity
D) moisture

Question

Quizplus · Accepted Answer

Gravity plays a key role in shaping the polarity of the body axes in chick embryos. The cells in the chick blastoderm differentiate into different cell types depending on their position, which is influenced by gravity. This ultimately determines the polarity of the developing embryo. Light, membrane potential, and moisture are not known to be primary factors in this process.
