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:
Gene therapy is an important application of biotechnology in which the mutated gene is isolated and then mutated gene is replaced by normal gene,the normal gene is integrated into a suitable vector and the vector is finally incorporated into the host which the diseased gene or matated gene is isolated.
Explanation:
Application of gene therapy
Gene therapy is used to treat various diseases such as severe combined immuno deficiency(SCID).
Benefits
Gene therapy helps to reat various life threatening diseases such as cancer,AIDS
Drawback
Gene therapy is very much expensive.
Risk
The main risk associated with gene therapy is that if the normal gene is targeted to the other part of the body instead of its original site then this can leads to mutation of another normal chromosome.
Explanation:
<u>-how long it takes for the voltage-gatedNa+ channels to close at the end of an action potential</u>
Neurons have unique structures which aid in facilitating communication by sending and receiving electrical signals very efficient.
The refractory period describes a period between the initiation of an action potential where Na+ channels are closed, and immediately after the action potential’s peak. Action potentials would require an influx of more positively charged ions; these must be more than a specific threshold in order to have the cells send along more action potentials which helps with figuring out stimulus intensity.
Potassium ions readily diffuse out of the cell more quickly than sodium due to the presence of more channels which allow for potassium leakage. The sodium pumps in neuronal membranes bring more Na+ than K+ ions into the cell; with every three sodium ions pumped out two potassium ions are brought in- this is in order to maintain the negatively charged membranes within the cell along with the resting potential.

Answer: The correct answer would be copper, nickel, or zinc.
Explanation:
Heavy metals such as copper, zinc, nickel have antimicrobial properties due to which they are used in various places to prevent microbial growth. For example, copper sulfate is used in fish tanks and swimming pools to prevent algal growth. Metallic copper and/or copper linings in incubators also help in reducing microbial contamination.
Coating of nickel or zinc is also used for the same purpose.
Thus, the correct answer would be copper, nickel, or zinc.
