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.
The tap root is advantageous to a plant in long periods of drought because it has a large storage of water and nutrients.
It is the largest and the most dominant root part in plants, which are sometimes thick, and grows straight downward.
I hope my answer has come to your help. God bless and have a nice day ahead!
The circular folds slow the passage of the partly digested food along the intestines, and afford an increased surface for absorption. They are covered with small finger-like projections called villi (singular, villus). Each villus, in turn, is covered with microvilli.
While rugae is only evident when an organ or tissue deflares or relaxes. The rugae unfolds for increase in volume . Plicae remains folded in the intestinal walls.
Rugae is not associated with the large absorptive surfaces in the small intestine.
i think the answer is convergent boundary
