A cell that just fertilized has to divide 6 times to form a 64 cell blastomere.
<u>Explanation:</u>
Human reproduction begins with the fusion of male gamete sperm and female gamete ovum. The fusion of sperm and ovum forms the zygote that is diploid. The zygote then undergoes mitotic division to develop into embryo.
The zygote first divides into two and the two individual cells divide again to form four individual cells and so on. Thus the number of cells after each division can be represented by the equation where n is the number of divisions. in the question it is given that the blastomere has 64 cells.
n=6
This means that the fertilized cell has to divide 6 times to develop into 64-celled blastomere.
Answer:
option c. viroid control
Explanation:
The chestnut tree in Europe is infected by a fungus called <em>Cryphonectria parasitica </em>that<em> </em>causes a disease called chestnut blight. The disease is controlled by a biological control method called hypovirulence.
The hypovirulence is a virus that attacks the fungal pathogen (<em>Cryphonectria parasitica </em><em>)</em> of chestnut tree. This fungal virus decreases the ability of fungal pathogen to cause chestnut blight disease. This technique prevents the chestnut plant after huge destruction of it in Europe.
The pathogen that have virus is introduced naturally over the plant. This reduces the infection and allows the natural growth of trees. Thus, option C is correct.
