Correct Answer: C. submitting to civil authorities

Correct Answer: A. parasitism

Explanation

Cows are not immune to ticks and thanks to their hairy hides, ticks love to attack herds of cattle. Feeding off their host's blood supply, ticks spend their lives on animals of all kinds, including cows. Ticks can even transmit potentially fatal diseases to cows through their bites. The cattle tick is considered to be the most important parasite of livestock worldwide

Correct Answer: B. is sensible

Explanation

The phrase 'has a good head on her shoulders' is an idiomatic expression that means someone is sensible, practical, and thinks before acting. Therefore, the most appropriate interpretation is that the daughter is sensible.

Correct Answer: A. Kidness to parents

Correct Answer: D) Ant

Correct Answer: C. 0.8225

Correct Answer: D. Temperature of the solution

Explanation

Options A, B, and C Are Correct

A. Position of the ion in the redox series: Ions lower in the electrochemical series require less energy to be reduced (at the cathode) or oxidized (at the anode). Therefore, they are preferentially discharged over ions positioned higher up. For example, in a dilute solution containing both \(H^{+}\) and \(Na^{+}\) ions, \(H^{+}\) is discharged at the cathode because it sits lower in the reactivity series.

B. Concentration of the ions: If an ion has a significantly higher concentration than a competing ion, it can override the standard position in the redox series (provided they are not too far apart in reactivity). For instance, during the electrolysis of concentrated \(NaCl\) (brine), \(Cl^{-}\) ions are discharged at the anode instead of \(OH^{-}\) ions due to their sheer abundance.

C. Nature of the electrodes: Electrodes can be inert (like platinum or graphite) or active (like copper or silver). Active electrodes actively participate in the chemical reaction and can alter which species gets discharged. For example, if copper electrodes are used in a copper sulfate solution, the copper anode itself dissolves into ions rather than discharging the negative anions in the solution.

Why Option D Is Incorrect

D. Temperature of the solution: Temperature affects the overall kinetic rate of the reaction, ion mobility, and the conductivity of the electrolyte. However, it does not dictate the selective or preferential discharge of one specific ion over another at the electrodes.

So the final answer is option D.
