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.
Be more specific? What are you asking
What experiment though lol
Animal cells are able to move because they do not have a cell wall like a plant does. Hope this helps, good luck!
Answer:
Option B
Explanation:
Flight-or-flight response is a response or physiological reaction towards external stimuli. Systematic desensitization is a methodology to control anxiety during speech. Hence, these two are not relaxation techniques. Transforming novelty into familiarity is also a methodology to remain prepared during a speech by practicing it well. Visualization is a technique that helps our mind to relax by using imagination to reach a relaxed state of mind.
Hence, option B is correct
