Answer:
Prophase
Explanation:
Prophase is the first stage in mitosis, occurring after the conclusion of the G2 portion of interphase. During prophase, the parent cell chromosomes — which were duplicated during S phase — condense and become thousands of times more compact than they were during interphase.
The energy released when a chemical compound reacts to produce new compounds is called Bonding Energy.
Answer:
Mass number or relative atomic mass number.
A portable digital pH meter will be best suited.
<h3><u>Explanation</u>:</h3>
The pH is the negative logarithmic expression of the concentration of hydrogen ions present in a solution. As its negative of the log of hydrogen ion concentration, so less it is, more is the hydrogen ion concentration. So a lower pH is acidic and higher is basic.
Now different indicators are used to measure the pH of a solution. Indicators can measure the pH of a solution both qualitatively and quantitatively.
Among the options given here, the litmus and cabbage juice are only qualitative measurers. So they aren't suitable here. Now the hydrion pH papers have the accuracy from 0.5 pH units to 0.25 pH units. Whereas the pH meter has the accuracy of 0.2 pH units to upto 0.01pH units. So the digital meter is much more accurate and scientific. As Candice is running her experiment most accurately, so she must use digital pH measurers.
