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>
Cancer cells continue to divide forever, with no limit
Both haploid and diploid yeast cells grow and reproduce this way. ... They can divide in such a way that the diploid number of chromosomes are reduced down to the haploid number. This kind of division is called meiosis.
Answer:
There are various reasons for the changes.
Explanation:
As new planets are discovering, the characteristics are changing accordingly. Larger planets are easy to detect and easy to study. Planets that are found closer to the stars are considered eclipsed planets rather than the planets which are farther from it.
These are the different reasons due to which the characteristics are changing. Another reason is that now scientists are discovering the signs of lives on different planets which are causing the change in its characteristics as well.
Detritivores are very important to energy transfer within an ecosystem because they are consumers that eat the trash and other wastes.
