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.
Answer:
207 ° C
Explanation:
De;
P1 / T1 = P2 / T2
Luego;
P1T2 = P2T1
P1 = I presión inicial = 7.5 atmósferas
T1 = temperatura inicial = 15 ° C + 273 = 288K
P2 = presión final = 12,5 atm
T2 = temperatura final =?
T2 = P2T1 / P1
T2 = 12,5 * 288 / 7,5
T2 = 480 K -273
T2 = 207 ° C
