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.

Answer:
Dopamine.
Explanation:
Cocaine is used as a recreational drug and addictive in nature. It can be smelled or directly inhaled in the veins. This drug causes the feeling of restless and happiness.
The dopamine is the important neurotransmitters that regulates the mood and other biological activity of the body. The cocaine inhibit the reuptake of dopamine and leads to its accumulation in the brain. This might also break the blood brain barrier.
Thus, the answer is dopamine.
Variation: When one of that species develops another trait or skill that the others do not have.
Adaptation: When a species changes in order to survive a certain place or survive a predator
Answer:
Explanation:
Enzyme are protein molecules that catalyzes chemical reaction.
In DNA replication, enzymes play a major role.
Enzymes identify the starting point of replication, attach itself and then unwind the Deoxyribonucleotide acid DNA Strand to form the replication fork.
Enzyme Helicase unwind and breaks the hydrogen bond between the base pair, opening up the helix structure to form a template for the new strand.
DNA polymerase also play a major role, it synthesis new DNA by adding primer to the DNA sequence for replication to occur, they also proof read the copy of DNA Strand being made to avoid errors during replication and add nucleotide to the growing DNA strand.
The answer is Mercury! Hope this helps
