Rarefaction is used for which of the following? a. creating a representative sample b. studying how disease impacts populations c. rediscovering species thought to be instinct d. determining which sea creatures live in an area

Rarefaction in terms of ecology can be defined as a technique used to assess species richness from the results of sampling.

It allows the calculation of richness of a particular species for a given number of individual samples, and these are based on the construction of rarefaction curves.

Hence, the correct answer is: option A-Creating a representative sample

Rarefaction is used for

a. Creating a representative sample is correct

Explanation:

Rarefaction is a method which is used to find the species richness by sampling. Rarefaction finds out the number of species present in the ecological community with the help of the rarefaction curve.

This Rarefaction curve is based on the number of species and the number of an individual sample.The curve size will increase first because the common species are detected after that curve will become plateau because only rarest species are there for the sampling.

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
