Answer:
Prophase
Explain:
The first step in mitosis, the nuclear envelope breaks down and chromosomes condense and become visible.

</span><span>The Klinefelter syndrome is caused by an insertion mutation. It occurs
when there is an existence of an excess or extra X chromosome in each cell that
may cause an abnormality in the development of males. It usually affects the
physical and cognitive development of male with symptoms varying from one
person to another. Kids with these type
of disorder may experience learning
disabilities and even speech and language
problems. These kids tend to be
quiet and very sensitive. They can also be very passive.

Answer:
See the answer below
Explanation:
<em>Recall that the law of dilution states that the number of moles before dilution must be equal to the number of moles after dilution.</em>
Mathematically,
molarity x number of moles before dilution = molarity x number of moles after dilution.
For solution A: final molarity = 3 mM, final volume = 2mL, initial molarity of KMnO4 = 10 mM
Applying the equation:
10 x initial volume = 3 x 2
initial volume = 6/10 = 0.6
<u>Hence, Tube A should be made with 0.6 mL of 10 mM KMnO4 stock and 1.4 mL of distilled water to give a solution of 2 mL 3 mM KMnO4.</u>
For solution B:final molarity = 8 mM, final volume = 2 mL, initial molarity = 10 mM
10 x initial volume = 8 x 2
initial volume = 16/10 = 1.6
<u>Hence, Tube B should be made with 1.6 mL of 10 mM KMnO4 stock and 0.4 mL of distilled water to give a solution of 2 mL 8mM KMnO4. </u>
