B. Anions have more electrons than protons, giving them a negative charge.  

D. Cations have more protons than electrons, giving them a positive charge.

Explanation - Ions are the result of atoms or molecules that lose or gain electrons. If an atom or a molecule is positively charged then it is called as cation and if it has negative charge then it is called as anion.

Cations have positive charge because the atom has lost its electron while anions have negative charge because the atom has gained the electron. The number of protons is more than the electron in cations and less in anions.

When conducting a population sampling study, on the first capture attempt, we _______ the captured individuals.
deff fn [24]

When conducting a population sampling study, on the first capture attempt, we tag, count, and release the captured individuals. Thus, option "D" is correct.

<h3>What is the mark-recapture method?</h3>

This is a method commonly used in ecology to estimate the animals in the population. A portion of the population is captured, marked and released. Another part of the population will, later on, be captured. This can be used to estimate the population in an assumption that the portion that was captured is proportional to the entire population. This is obtained by dividing the number of marked individuals by the individual marked on the second capture. This is one of the simplest and most practical methods of estimating the population.

Thus, option "D" is correct.
