The answer is; in the summer
Insects such as blowflies increase their population in the summers when the temperatures are warm. One reason is that most insects are ectotherms hence their body temperatures are dependent on ambient environmental temperatures. In addition, the maggot stage of the blowfly pupates mostly in warm and dry conditions hence increasing winged flies populations in the summer.
A. they both have prophase and metaphase. Mitosis and meiosis have the same steps, just a few of the steps are different, and in meiosis the steps are done twice.
During Prophase chromosomes condense, and mitotic spindle form, chromosomes are copied, and the nuclear membrane disappears, spindle fibres pull the sister chromatids apart.
Explanation:
Prophase is divided into 2 sub-phases as early Prophase and late prophase.
Early Prophase:
In early prophase distinct thick chromosome like structures, Centrioles move to the opposite poles and, nuclear membrane disappears
By late prophase:
Astral rays and spindle fibres are formed. Spindle fibres attach to the chromosome. Contractions occur in the attachment and sister chromatids are pull apart towards the equator.
Metaphase will follow the prophase.
Very, very rare. Uranium used in power plants is typically only 3% U-235 (the explosive stuff), while bomb-grade uranium is nearly pure U-235. Simply, the concentration of U-235 in reactor-grade uranium is too small to start a chain reaction and detonate like a bomb.
