Indirect methods like mark and recapture become a strong tool to estimate population size or density in species on which it is impossible to apply a direct methods. Because of their biological and ecological characteristics, the Gypsy moth and the Green lizard populations are good examples for which mark and recapture would work well.

------------------------------------------------------

There are different methods to study population density. There are direct methods and indirect methods. Among these last ones, we might find the Mark-Recapture technique.

The Mark-Recapture technique assumes that

the population is closed during the sampling season, there is no mortality nor natality,
marks in the individual last the whole sampling season, and they do not affect the marked individual or their behavior.
marked individuals are randomly distributed in the population, and
all the individuals have the same probability of being sampled.

The method consists of capturing a sample of individuals belonging to the population under study. After capturing the individuals, the researcher marks and releases them again. The third step is to sample again: The researcher captures new individuals and counts how many of them are marked. These marked individuals belong to the first sample.

Indirect methods like this become a strong tool to estimate population size or density in species on which it is impossible to apply a direct method such as counting individuals.

For instance, if we need to estimate insects population density (Gypsy moth population) or reptiles population density (Green lizard population) because of their biological and ecological characteristics, the best way of doing it is by applying indirect methods. These species characterize as small-sized, fast to escape, they can hide in small inaccessible places, they have nocturnal habits, their reproductive rate is too high, and their distribution rate is wide. Among many other characteristics, their population density can not be estimated by direct methods. Mark-Recapture technique is the most suitable one.

Which of the following statements is true?

kogti [31]

The correct answer is option D, that is since genetic drift is random, it does not always favor the better or healthier organisms.

A mechanism of evolution in which the frequencies of alleles of a population change with generations because of sampling error is known as genetic drift. It takes place in all the populations of non-infinite size, however, its influences are strongest in small populations.

EastWind [94]

The bone that is situated next to the eardrum is called the malleus.

The bone that sits next to the oval window is called the stapes.

Given,

The bone that is situated next to the eardrum is called the __________; the bone that sits next to the oval window is called the __________.

We need to fill in the blanks.

<h3>What are eardrums and their parts?</h3>

The eardrum is a transparent gray membrane and there is a middle ear

bone called the malleus attached to the center part of the drum.

The space inside the ear drum is called the middle ear.

The three smallest bones of the body are found in the middle ear.

They are:

- The hammer (malleus)

It is attached to the eardrum.

- The anvil (incus)

It is in the middle of the chain of bones.

- The Stirrup (stapes)

It is attached to the membrane-covered opening that connects the middle ear with the inner ear (oval window)

Thus

The bone that is situated next to the eardrum is called the malleus.

The bone that sits next to the oval window is called the stapes.
