Question

Yolk molecules tend to accumulate in the vegetal half in the fertilized eggs of most animals, and the presence of yolk can slow down cell division. Based on this observation and assuming there has been no movement, cells in the vegetal half of the embryo should be (blank) those in the animal half and there should be (blank).

Answer 1

cells in the vegetal half of the embryo should be unpigmented those in the animal half and there should be heavily pigmented.

Explanation:

The Yolk molecules moving in the vegetal halves of the egg which is the case in most of the animals, slows down the cell division. These lesser division area or the zone demarcates the area to be vegetal pole and due to lesser cell division, it becomes unpigmented or less pigmented Based on the observation time and perspect with assuming no movement.

The pole opposite to the vegetal, is animal pole which with absence or less of yolk, gets more ability to divide and hence become more pigmented or heavily pigmented. This brings polarity to the egg and becomes telolecithal egg.
