a mature egg is fertilized when it is joined with a sperm cell
the answer is B
Interphase: Add mushrooms to represent organelles and a ring of pepperoni to make a nuclear membrane. Strips of peppers would represent the DNA inside the nucleus. To model the end of interphase, double the number of mushrooms on the pizza to indicate the copying of the organelles. Double the number of peppers inside the nucleus to represent the replication of DNA.
Prophase: Pair strips of pepper inside the nucleus to show the formation of chromosome pairs. Strips of aluminum foil would represent spindle fibers.
Metaphase: Line up the pair of peppers along the middle of the pizza. Removing the pepperoni would show the breakdown of the nuclear membrane.
Anaphase: Split up the pairs of peppers, and show the spindle fibers, made of aluminum foil, pulling them to either side of the cell.
Telophase: Make two new nuclear membranes around the pepper strips using pepperoni. Separate the pairs of peppers to show the chromosomes unwinding.
Cytokinesis: Cut the pizza across the middle to show the cell dividing into two daughter cells.
Answer:
One of the positive consequences of nuclear power plants is that it produces small amounts of air pollution. Comparing it to coal power plants, nuclear reactors has less or no production of air pollution while in operation. It is by far one of the power plants with least contribution to air pollution.
