You just have to describe on how the cell structure will describe themselves .
A virus is basically a shell of DNA. It floats around until it finds a cell to latch onto. It then tricks the cell into absorbing the virus and the virus unleashes the DNA its carrying telling the cell to quit doing its job, and make more of the virus. <span />
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.
Hola!
