A benefit of using nuclear energy could be the abundance of uranium in nature. The human risk about mining that is the most important to consider are the health hazards that are associated with uranium mining.
The answer is : 32S has 16 neutrons, whereas 35S has 19 neutrons. If the isotope 32S has 16 protons and 16 neutrons, the isotope 35S will have 16 protons and 19 neutrons.
The lac repressor prevents the lac genes in the DNA of E. coli from being expressed most of the time. The answer to your question is A. I hope this is the answer that you are looking for and it comes to your help.
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.
C. A vertebrate because a vertebrate animal has a backbone. :)
